Megapixel network cameras to explore the actual situation
Q: Why is the market Megapixel infrared machines are rare ?
Answer : Millions of HD has been for many years the concept of indoctrination, whether in security exhibitions, magazines or the media are filled with various brands of one million high-definition network camera , but independent research and development and the ability to bulk sales of one million high-definition brand , but few, but can the IR Megapixel manufacturers is less. Many companies from here to buy development board solution providers and programs can be easily mistaken developed marketable products , not knowing , digital camera auto-focus , color correction, network transmission, illumination and so need to improve their own development, solution providers only provide a preliminary semi . Just out of the picture , a lot of development work required to complete their own , so the failure rate is very high. If the manufacturer even the common Megapixel IP Camera are not successfully launched , not to mention the million infrared machines . Megapixel IR dryer, solution providers did not plan , you need to develop and control their own color ( do not sense infrared ) and black and white ( sense infrared ) switching software .
Q: How many Megapixel domestic manufacturers ?
A: According to the semiconductor company statistics, the domestic participation in research and development Megapixel network camera manufacturers as many as one hundred or more, TI's DaVinci DM3XX series with American APTINA company 9P031 for the combination of solutions , there are hundreds of companies , total domestic purchased this program and the development board . But in 2012 , the vast majority in 3A technology, large amounts of data network transmission technology point stumble , only a very few successfully developed and marketed , in which intelligence is the only one to achieve a fully autonomous technology developed 3A manufacturers will eventually Megapixel cameras one by one break of the key technologies , TI and APTINA company become an important cooperation and support objects. In all types of security exhibition, although you can see that many manufacturers millions of high-definition display their products, but really all independent development and mass production of only two or three companies , semi- independent development and definition of the manufacturers can not sell one million to 5 .
Q: China has independently developed Megapixel high-speed ball?
A: In the analog era , the domestic high-speed ball movement , mostly Japanese and other imports , high-speed ball a key technical point is the auto-focus section, which functions are controlled by the chip to achieve, and as such, have no chance to develop their own domestic companies auto focus, so the domestic analog high-speed ball , had to be imported movement. And into the digital high-definition era, there are a few R & D strength of domestic enterprises, the part of the technology developed by the software running on ARM to achieve autofocus and intelligent control , thus breaking the Japanese and Korean semiconductor manufacturers and the lens or camera technical monopoly. In China, will become Megapixel Speed Dome important supplier .
Q : Millions of HD video recorder with DVR Embedded Embedded What is the relationship ?
A: They belong to the same video recorders, software technology and function in a very similar and interlinked nature , but only a few digital DVR manufacturers have the opportunity to shift to digital high-definition embedded video recorders , first of all, do one million high-definition video recorder, too you have to have independent R & D capability and competitive digital HD camcorders, cameras have advantages , and secondly, the technical difficulty million high-definition video recorder is much higher than embedded DVR, now approaching one million high-definition embedded video recorders do not plan to buy the finished product , independent research and development is a simple thing, and one million high-definition VGA resolution must be higher than 1024X768, usually mostly 1920X1080, VGA output resolution of such a large brand in embedded DVR is rare . Another Megapixel decompression requirements are high, because the high resolution , large amount of data , the integrity of the software technology has improved.
Q: Megapixel cameras are not just buy a set of programs became factory ?
A: buy a set of programs to become Megapixel IP camera manufacturers idea is impossible. First , the camera solution providers will usually photoreceptor current mainstream processor to make a camera with a semi , and then sold to the manufacturers want to develop one million high-definition , but due to solution providers themselves less contact with contractors , they can only develop some basic functions , and the rest need priced self-development . Second, once the chip was later introduced new photoreceptors , and not a direct replacement for the photoreceptor , which requires solution providers to re- write auto white balance , auto exposure and auto- focus software upgrade is very troublesome. Once again, the country has very few camera manufacturers 3A technology , coupled with the capture of the front camera , manufacturers also need to make the corresponding video , which will be the development of high-definition million threshold referred to new heights. Therefore, in million high-definition era, only with a strong R & D and the overall strength of the manufacturers.

Q: What digital camera is a network camera before you ?
A: Digital cameras , according to the difference in transmission mode , a USB camera ( that is, the field of IT computer camera ) and network cameras , and IP Camera are usually divided into two types , one is the front-end based on analog CCTV cameras , followed by video processing and network transmission module , this camera has many of the same drawbacks analog cameras , no more than the highest quality D1, the other is pure digital high-definition video camera , it does not repeat the digital to analog conversion , directly to digital video processing and network transmission out. The latter will replace the digital high-definition network cameras former traditional network cameras.
Q: Megapixel IP cameras occupy hard big?
A: Megapixel IP Camera, pixels high naturally occupied hard disk capacity is large, but because it is a digital signal camera , you can do better signal to noise ratio , the picture is clean, snowflake points less , thus saving a lot of disk space . With 720P HD , for example, takes an hour each way video 1G hard disk space can be controlled in less than analog monitor with D1 resolution video stream considerably .
Q: Megapixel IP cameras is not pixels the higher the better ?
A: Megapixel IP camera, if appropriate choice of photoreceptors and video compression processor , you can easily do 1,300,000 , 2,000,000 , and even 500 million pixels . However, not more pixels, the higher the value of the camera application . For security surveillance cameras , in addition to considering pixels, while also considering the illumination . And generally the higher the pixels , illumination worse , pixel and illumination is inversely proportional to the other pixels, the stream will be greater capacity and disk footprint . In many sellers live show, the camera more than 2,000,000 pixels in effect , most of the viewfinder bright outdoor light , indoor show rarely under low light surveillance video , which is actually a misleading buyers .
Q : Millions of how the quality of high-definition network camera ?
A: Currently Megapixel network camera , also belong to the emerging high-tech products , is still in the early stages of development , did not enter the price battle, because with a reasonable profit guarantee , while bigger companies are generally not on the quality of relaxed, natural we do not need such as analog cameras , because profit is very thin and cut corners to make things , whether it is chips, electronic components, or infrared lamps are used is a quality assurance brand goods , longer service life .
Q : Millions of high-definition era , CMOS will largely replaced the CCD?
A: In the era of analog monitor , CCD because of early development , while providing a complimentary full technical program , has been favored by many camera manufacturers . However, the development of CMOS chips late step , early technology behind the CCD, plus a full set of technology solutions mature much, so do not give good. Later , CMOS chip technology has been developing rapidly , low-light performance is also improved significantly, especially in the field of mobile phones and other consumer electronics , is already extensive use of CMOS sensor , a lot of high-end digital camera is a CMOS instead of CCD. In recent years, companies such as American APTINA increased emphasis on the field of security , cost-effective CMOS chips began to flow to the field of security , and thus be in the security field position CCD produces impact, especially into the era of digital high-definition , digital high-definition video camera gradually replacing analog cameras , CMOS has replaced the CCD into the mainstream trend.
Q : CCD HD network camera with millions of millions of high-definition CMOS compared to illumination will be better?
A: According to the photoreceptor semiconductor company's technical staff to say , the same sensitive area , the more pixels , each pixel of the photosensitive area is smaller, each pixel on the number of photons received less natural light photoreceptor sensitivity worse . Many people often mistakenly take hundreds of thousands of pixels , 1/ 3 ' inch CCD analog cameras to go with the 1/3' inch CMOS Megapixel IP Camera compare illumination effect, which draw the wrong conclusions , that better illumination CCD . In fact, APTINA Company 1/3 ' inch 1,300,000 pixel chips made using low-light cameras and a Nissan 1/ 3' inch CCD chips made of 1.3-megapixel digital high-definition network camera for low-light effect of contrast , in the same conditions , CMOS is not only inferior to CCD, but visually far beyond the CCD million cameras.
Q: What do one million high-definition monitor whether the time is ripe ?
A: Several years ago , security industry had already started to sing "Million HD" trend , but they are thunder, little rain , mainly due to the time the domestic Megapixel immature technology . Today , whether it is from a technical point of view or the market demand, to make one million high-definition monitor timing are ripe. On the technical side , that represents the number of domestic companies have tackled the camera from the front to the back-end storage , and network transmission and other aspects of the problem, to achieve a clear picture quality, low light , wide dynamic range and other functions, and the results are better than traditional analog cameras , with a very high price. Second, from the customer's point of view, analog monitor has been unable to meet the market definition , intelligence requirements, Megapixel surveillance has become the market mainstream appeal points . However, due to contractors and end- users Megapixel always lack a thorough understanding of , so many people are still on the sidelines. 2010 million high-definition , the security companies to seize the opportunity is bigger and stronger competition in the market the necessary conditions , if you wait a million industry completely universal definition , then the business may be out of the market and consumers , can also cause enormous waste of social resources .

Teach you to do a smart network camera buyers
Teach you to do a smart network camera buyers
Network Camera is a high-tech new products, due to security across the network and the two little before the stakeholders in the industry , Gehangrugeshan , engage in surveillance networks do not understand , do not understand the monitoring network , which gives the already blurry webcams cast a veil of mystery . For now, the dealer camp, most of the sales staff know it is only at the level of the water Flower in the Mirror of hazy . Let alone a buyer . The vast majority of buyers or to one thinks , or to speak by the price . Result is that buyers can not buy the right products , soon put the product into the Recycle Bin. Money is spent , not accomplishing things .
This article will teach you to know about network cameras, make a smart buyer.
First, recognize network camera :
We need first to understand the network cameras. Network camera called IP CAMERA ( abbreviated IPC) by the network coding module and analog camera combination. Network coding module analog cameras capture analog video signal into a digital signal compression coding , which can directly access the network switching and routing equipment ( switches, routers, these two products for the network users are not familiar with it ) , and then access the Internet. IPC own IP address , some brands of IPC also comes with a domain name. LAN users can log in to view the IP address of the IPC and control surveillance video management and recording. Remote users can log in through the IPC IPC domain name to watch , control, management, and video. Both LAN users or remote users to log IPC available through a web browser (IE) and the corresponding video centralized management software.
Relative to analog cameras , IPC network camera can be easier to achieve control especially remote monitoring, construction and maintenance easier , better support for audio , better support alarm linkage , more flexible video storage , richer product selection , more high-definition video effects and more perfect monitoring and management. In addition , IPC supports WIFI wireless access , 3G access , POE power supply ( network-powered ) and fiber access . IPC for the emergence of network and security industry landmark historical significance.
Most of the IPC shape and analog cameras almost, because IPC is often used in homes and offices , taking into account aesthetics , IPC has richer and more beautiful shape . If VStarcam of T7892WIP, T7838WIP.
IPC 's great value . To install it at home , you can see the home anywhere in real time : to understand the child 's learning , caring for the elderly , to see pets ; install it in the shop , you can visit a shop without leaving home : Understanding the work of the staff , traffic analysis, display cases and other goods ; install it in the product exhibition room, you can feel free to let customers see samples of distant ; install it in the hospital , the patient can get distant doctors' consultation is no exaggeration to say that , IPC can be installed in any one place , IP Camera eventually into millions of households , into the various sectors of society in various fields so as to make a significant contribution to the harmonious development .
Second, the network camera several key parameters
1 ) Lens
Lens is a video capture first off , the lens will naturally affect the quality of the video effects, although there are many lenses , a great effect on the video , shot in price from tens of dollars to several thousand dollars. However, surveillance is still not a few million to buy the lens , lenses are available in the market and therefore are basically similar. However, the focal length of the lens effect of the video is worth noting , which means that you should consider when selecting products whether you choose a model with interchangeable lenses , or to consider whether to select the zoom lens. Here have to mention , zoom refers to the focal length of the lens can be changed . Some IPC functionality with digital zoom , digital zoom means that you can view the video image to enlarge , did not change the sharpness of the image , the application of the IPC little value . Beware some are not particularly professional sales staff or JS one concept .
2 ) Image Sensor
This is the impact of the key factors of video effects . There are currently two kinds of CMOS and CCD , CCD dynamic range and clarity is good, technology is very mature , both picture quality and anti- noise capability , but its weakness is the power consumption , high production costs ; while COMS development today , of the various indicators was close CCD, and low power consumption , low cost advantage, so now there are many manufacturers will choose as a photosensitive core components using CMOS .
3 ) video compression algorithm ( also known as video compression format ) .
This is the IP network camera the most important key factor , because it directly determines the video resolution , video fluency and video storage space. And through my years of understanding, this was always the most important factor is the seller intentionally or unintentionally avoided , because it may be in itself can not tell where Cn , or shoddy motives. But as a savvy buyer you must understand clearly. IPC currently on the market are mainly H.264, MPEG4 two video compression algorithms. Stronger H.264 compression , video loss is less, so clearer and more fluid. The former can support the 25 frames / second frame rate , which is generally not more than 10 frames / sec . This means that the latter's video is not coherent, not real ; since MPEG4 compression ratio is not big enough , if you do the whole real-time , stream is too large, it is difficult to see the remote .
4 ) image format
Image format of the video image is to determine the actual number of pixels , of the DVD format , and VGA (640 * 480) format, and CIF (352 * 288) form two kinds , DVD image format family contains D1 (720 * 576 interlaced scanning ), D2 ( 1048 * 720), D3 (1920 * 1080 interlaced ), D4 (1280 * 720 progressive scan ) and D5 (1920 * 1080 progressive scan ) five kinds of image formats , the current mainstream market for D1. supports D3 and D4 of megapixels is also listed, but due to its large bandwidth , is not widely applied .
Different pixels with different image format , video file sizes are not the same . If it is not the same image format, we can not alone recording hard disk size required to determine the merits of the IPC . An IPC image formats can often be adjusted, which means that if your hard disk space is not big enough, but require a longer recording time , it can be achieved by reducing the image format .
5 ) Frame Rate
As we all know , any video files are composed by a continuous picture , a picture we call it a , like a second of video images from the 25 contiguous composition , when the frame rate is 25 frames / sec. In the PAL standard , 25 frames / sec video performance can be very realistic action . If less than 25 , the video of the action will not consistent , the lower the more incoherent even be jumping movements artifacts . Therefore, the frame rate is very important in video surveillance . This parameter is the interface between the video monitor will show it. This parameter , also was a lot of not very professional salesperson avoided. We buy products must pay attention to this , because if can support 25 frames / sec IPC cost difference as well.
6 ) dual-stream
Some IPC is designed to support two video signal, i.e. a so-called dual-stream . Benefits of dual-stream stream is watching all the way , all the way to stream memory and storage are used than watch stream all the way to more effectively prevent network congestion , so that it can better protect the video in effective network bandwidth fluency.
7 ) front-end storage
Some of the IPC with an SD card slot or USB removable storage interface, we called the front end of its storage tube . Front-end storage is often used to monitor bandwidth is not very adequate environment . Some environmental inconvenience Zhuangkuan Dai , the use of front-end storage capabilities , thus saving play a video surveillance monitoring results, to say that is an option.
8 ) Product Line
Most of the larger surveillance systems, often applied to various types of products, due to the current all -party video management software and is compatible with other brands of IPC is difficult . Therefore, in order to monitor the system choose the brand , it is necessary to consider whether the brand has a rich product line to be able to meet the needs of a variety of environments , as well as system solutions capabilities. Such as support for infrared , support WIFI wireless , support POE, supports fiber access, support PTZ , support zoom, so if there is video server with some special combination of analog cameras and whether the video decoder can access the TV wall and so on.
9 ) Software Features
Most monitoring systems require centralized management, so the video management software features are powerful , the interface is friendly and also in product selection must be taken into account. Management software modules more, so the identification of the merits of video management software requires comprehensive consideration , can not be overstated certain function , a function can not ignore the need to take the actual demand .
In addition to these nine outside , infrared night vision capability , ultra- low-light , wide dynamic range , light suppression and other functions are also some important parameters of IPC . In summary , IPC selection needs to have a certain expertise and to be more patient . Do not choose expensive just choose right , I hope you choose to own a suitable IP network camera.

For now, the dealer camp, most of the sales staff know it is only at the level of the water Flower in the Mirror of hazy . Let alone a buyer . The vast majority of buyers or to one thinks , or to speak by the price . Result is that buyers can not buy the right products , soon put the product into the Recycle Bin. Money is spent , not accomplishing things .
This article will teach you to know about network cameras, make a smart buyer.
First, recognize network camera :
We need first to understand the network cameras. Network camera called IP CAMERA ( abbreviated IPC) by the network coding module and analog camera combination. Network coding module analog cameras capture analog video signal into a digital signal compression coding , which can directly access the network switching and routing equipment ( switches, routers, these two products for the network users are not familiar with it ) , and then access the Internet. IPC own IP address , some brands of IPC also comes with a domain name. LAN users can log in to view the IP address of the IPC and control surveillance video management and recording. Remote users can log in through the IPC IPC domain name to watch , control, management, and video. Both LAN users or remote users to log IPC available through a web browser (IE) and the corresponding video centralized management software.
Relative to analog cameras , IPC network camera can be easier to achieve control especially remote monitoring, construction and maintenance easier , better support for audio , better support alarm linkage , more flexible video storage , richer product selection , more high-definition video effects and more perfect monitoring and management. In addition , IPC supports WIFI wireless access , 3G access , POE power supply ( network-powered ) and fiber access . IPC for the emergence of network and security industry landmark historical significance.
Most of the IPC shape and analog cameras almost, because IPC is often used in homes and offices , taking into account aesthetics , IPC has richer and more beautiful shape . If VStarcam of T7892WIP, T7838WIP.
IPC 's great value . To install it at home , you can see the home anywhere in real time : to understand the child 's learning , caring for the elderly , to see pets ; install it in the shop , you can visit a shop without leaving home : Understanding the work of the staff , traffic analysis, display cases and other goods ; install it in the product exhibition room, you can feel free to let customers see samples of distant ; install it in the hospital , the patient can get distant doctors' consultation is no exaggeration to say that , IPC can be installed in any one place , IP Camera eventually into millions of households , into the various sectors of society in various fields so as to make a significant contribution to the harmonious development .
Second, the network camera several key parameters
1 ) Lens
Lens is a video capture first off , the lens will naturally affect the quality of the video effects, although there are many lenses , a great effect on the video , shot in price from tens of dollars to several thousand dollars. However, surveillance is still not a few million to buy the lens , lenses are available in the market and therefore are basically similar. However, the focal length of the lens effect of the video is worth noting , which means that you should consider when selecting products whether you choose a model with interchangeable lenses , or to consider whether to select the zoom lens. Here have to mention , zoom refers to the focal length of the lens can be changed . Some IPC functionality with digital zoom , digital zoom means that you can view the video image to enlarge , did not change the sharpness of the image , the application of the IPC little value . Beware some are not particularly professional sales staff or JS one concept .
2 ) Image Sensor
This is the impact of the key factors of video effects . There are currently two kinds of CMOS and CCD , CCD dynamic range and clarity is good, technology is very mature , both picture quality and anti- noise capability , but its weakness is the power consumption , high production costs ; while COMS development today , of the various indicators was close CCD, and low power consumption , low cost advantage, so now there are many manufacturers will choose as a photosensitive core components using CMOS .
3 ) video compression algorithm ( also known as video compression format ) .
This is the IP network camera the most important key factor , because it directly determines the video resolution , video fluency and video storage space. And through my years of understanding, this was always the most important factor is the seller intentionally or unintentionally avoided , because it may be in itself can not tell where Cn , or shoddy motives. But as a savvy buyer you must understand clearly. IPC currently on the market are mainly H.264, MPEG4 two video compression algorithms. Stronger H.264 compression , video loss is less, so clearer and more fluid. The former can support the 25 frames / second frame rate , which is generally not more than 10 frames / sec . This means that the latter's video is not coherent, not real ; since MPEG4 compression ratio is not big enough , if you do the whole real-time , stream is too large, it is difficult to see the remote .
4 ) image format
Image format of the video image is to determine the actual number of pixels , of the DVD format , and VGA (640 * 480) format, and CIF (352 * 288) form two kinds , DVD image format family contains D1 (720 * 576 interlaced scanning ), D2 ( 1048 * 720), D3 (1920 * 1080 interlaced ), D4 (1280 * 720 progressive scan ) and D5 (1920 * 1080 progressive scan ) five kinds of image formats , the current mainstream market for D1. supports D3 and D4 of megapixels is also listed, but due to its large bandwidth , is not widely applied .
Different pixels with different image format , video file sizes are not the same . If it is not the same image format, we can not alone recording hard disk size required to determine the merits of the IPC . An IPC image formats can often be adjusted, which means that if your hard disk space is not big enough, but require a longer recording time , it can be achieved by reducing the image format .
5 ) Frame Rate
As we all know , any video files are composed by a continuous picture , a picture we call it a , like a second of video images from the 25 contiguous composition , when the frame rate is 25 frames / sec. In the PAL standard , 25 frames / sec video performance can be very realistic action . If less than 25 , the video of the action will not consistent , the lower the more incoherent even be jumping movements artifacts . Therefore, the frame rate is very important in video surveillance . This parameter is the interface between the video monitor will show it. This parameter , also was a lot of not very professional salesperson avoided. We buy products must pay attention to this , because if can support 25 frames / sec IPC cost difference as well.
6 ) dual-stream
Some IPC is designed to support two video signal, i.e. a so-called dual-stream . Benefits of dual-stream stream is watching all the way , all the way to stream memory and storage are used than watch stream all the way to more effectively prevent network congestion , so that it can better protect the video in effective network bandwidth fluency.
7 ) front-end storage
Some of the IPC with an SD card slot or USB removable storage interface, we called the front end of its storage tube . Front-end storage is often used to monitor bandwidth is not very adequate environment . Some environmental inconvenience Zhuangkuan Dai , the use of front-end storage capabilities , thus saving play a video surveillance monitoring results, to say that is an option.
8 ) Product Line
Most of the larger surveillance systems, often applied to various types of products, due to the current all -party video management software and is compatible with other brands of IPC is difficult . Therefore, in order to monitor the system choose the brand , it is necessary to consider whether the brand has a rich product line to be able to meet the needs of a variety of environments , as well as system solutions capabilities. Such as support for infrared , support WIFI wireless , support POE, supports fiber access, support PTZ , support zoom, so if there is video server with some special combination of analog cameras and whether the video decoder can access the TV wall and so on.
9 ) Software Features
Most monitoring systems require centralized management, so the video management software features are powerful , the interface is friendly and also in product selection must be taken into account. Management software modules more, so the identification of the merits of video management software requires comprehensive consideration , can not be overstated certain function , a function can not ignore the need to take the actual demand .
In addition to these nine outside , infrared night vision capability , ultra- low-light , wide dynamic range , light suppression and other functions are also some important parameters of IPC . In summary , IPC selection needs to have a certain expertise and to be more patient . Do not choose expensive just choose right , I hope you choose to own a suitable IP network camera.

What is a network camera depth analysis
What is a network camera ? What is a network camera depth analysis
Today Granville Xindakang technical staff as we talk about what is a IP Camera , through this article I hope everyone on the network camera have a deeper understanding.
IP Camera and network video camera the name suggests is a combination of a high-tech technology products , not only with the traditional image capture cameras all functions , the machine also comes with a digital compression controller and WEB-based operating system, making the video data after compression , via LAN , internet or wireless network to the end users. The remote user can own a PC using a standard IE browser, according to the IP Cameracomes with a separate IP address to access the network cameras , real-time monitoring target site conditions , and on the real-time editing and storing the image data , It also can be controlled via the network PTZ cameras and lenses , for all-round monitoring.
From the network camera's external structure, network cameras currently on the market there is a lens for the integration of embedded models , this network camera lens is fixed and can not be changed ; another you may need to replace the standard C / CS mount lens, but with a C-type lenses must CS-C converter with the installation. However, the internal structure , said either model, the basic structure of the network camera mostly by the lens, filter , image sensor , digital image processor , and a compression chip with network connectivity server components. IP Camera as the camera in the new family member , also has the same operation with the ordinary camera performance , for example , with automatic white balance, electronic shutter, auto iris, auto gain control, automatic backlight compensation function . On the other hand , due to network cameras with networking capabilities , so they can support multiple users to connect at the same time , some network camera also has a dual function , can simultaneously achieve analog output and digital output network .
Understanding of the network camera, we detail next network video server. From a certain point , the video server can be seen as a network camera without a lens , or without hard drive DVR, its structure is substantially similar to the network camera is determined by one or more analog video input port , digital image processor, the compression chip and a server with a network connection function of the composition. The input video servers digitize analog video signal processing, digital signal pattern sent to the network , enabling real-time remote monitoring purposes. Since the analog camera video server successfully " transformed " as network cameras, so it is also a network monitoring system with the current analog CCTV systems to integrate the best way. In addition to video servers and nnetwork camera can achieve the same function, the device configuration is more flexible. IP Camera are usually subject to its own lens and body functional limitations , and video server in addition to conventional cameras can be connected to the ordinary , but also to some of the special features of the camera is connected , for example: low-light cameras , high sensitivity infrared cameras.

Quality determines the future of high-definition IP Camera
Quality determines the future of high-definition IP Camera
Many dealers consult our HD network camera always ask when the price could be lower it ? Even wait for them to be sold for the price of simulation , today I Talking about positioning in the end and low-end difference.
Once in the market, many people will be upset simulated profit is too low , the constant pursuit of dealers to the manufacturers to ask for the reserve price has become a qualitative thinking, while undesirable Elgin , blindly ask for cheap , low-end market from the current awareness of the general public view , the low end is always cheaper to continue to closely follow the market down, if the price is slightly higher because the feeling that many people would feel expensive, but from an engineering point of view , the performance is overwhelming , or why so many people go with well-known brands , Kang Dahua such as the sea .
In view of the future of high-definition IP Camera market , maybe a year later , the cost of high prices down , and choose to take the low-end will be further compressed margins , continue to fight further lower prices , just like today's analog market , and some even earn five ten block margin, only harms himself harm peers , into a vicious cycle that is not necessary . Low production cost savings are often the product of , for example, an infrared eighty dollars could have been replaced by something but twenty dollars . As a long-term development of the enterprise would need to focus on the future .
Today's simulation market, the real earnings of those in a clear brand positioning , while the low end too much, very often there is no technical maturity, resulting in various problems on engineering applications , final and customers is just a one-time deal. Network HD Monitor comes, technology maturity is particularly important, not just a hardware can be achieved to meet the standards must be software, hardware, applications are relatively mature in order to achieve high-definition network camera application standards . This is our future Megapixel select manufacturers market selection , positioning strategy time when deliberate.
So Granville Xindakang in a relatively mature technology , to ensure value for money in the case , the product positioning in the high-end would be more suitable for relatively low-end high-definition future.

How to choose the network camera dealer
How to choose the network camera dealer
We buy things , they both prefer value for money thing, but as a dealer is not this happen ? I think if it were me , I would choose a big profit , sales are good , good promotion , can make money .
So today we will talk about how do we choose high-definition network camera.
First, we should consider is that manufacturers can not be long-term supply , not today, I'm here to buy this product, but also do a good job related to the promotion, over a period of time , our sales up, more customers , but customers are not in the production of this product , so things will particularly troubles !
Secondly, we need to consider is the manufacturer's maintenance situation , IP camera better than analog cameras , especially Megapixel network camera, their installation and use of the process will encounter some problems , if the manufacturer can not provide technical the service we give our customers the time of installation does not solve problems , then this time is we are particularly worried , finally got a list but it working !
Finally, we consider that the quality of products , and now we are talking about selling products are sold in selling human communication, but as a distributor , we are the most direct to customers, we also have to consider the quality of the product , as long as the where the product is a problem customers find the first time or are we these dealers ! So we select the IP camera , be sure the quality of the product have to be a test , for example , the product of image quality, product life and so on.

Installing an outdoor network camera time to pay attention to what issues
Installing an outdoor network camera time to pay attention to what issues
Webcams in the use of the process as the environment changes , we encounter problems during installation are not the same , we are in the process of the installation should pay attention to the problem is not the same .
First, the network camera is installed outdoors , we have to give it installs a shell , used to increase the useful life of the IP camera . Outdoor cameras are generally used auto zoom , you can adjust the image sensor light needed to improve the dynamic network camera features , and protects the image sensor from light damage .
So in our specific installation process should pay attention to what the problem?
First . Lighting problem . Use night network camera , in order to avoid reflections and shadows, usually require lighting equipment, you can use infrared lighting to replace ordinary light bulbs . However, users must use the black and white camera with infrared lighting equipment and network video server, because black and white camera more sensitive to infrared light-sensitive , and you can not play the infrared color camera functions .
Second . Avoid direct sunlight shoot the problem . Avoid direct sunlight appear in the image . Direct light makes the camera can not capture images , and could sensor chip color filter on a permanent bleaching, resulting image is streaked . If possible , the installation required to maintain high-definition IP camera with sunlight in the same direction , and try to avoid shooting at the sky .
Third . Amplifier gain problem . In the computer can adjust the gain level of the image sensor , the higher the gain , the better the performance in low light , but the interference will expand . In low light , the user can use the high gain to achieve better performance , in the light of good quality , the user using a low -gain the same access to high- quality images.
Fourth . Shutter speed issues . Usually the shutter speed should be set to 1 /50 or 1/60 sec ; long exposure time when the light is weak , good performance can be obtained . If you want to capture fast- moving images , the shutter speed should be set to 1/ 10000 seconds . Select the appropriate desired lens becomes very important.
As long as you have installed the indoor network camera technology , and then pay attention to these four points that you have installed on the outdoor IP camera no problem !

Cheap HD network camera can achieve high targets ?
Cheap HD network camera can achieve high targets ?
In many people 's minds are so many words : not good goods cheaper . Where the price is not high things, so many people people born sigh. In recent years , hd ip camera universal application , its unique clear, detailed images in the visual effects allow users to have a new experience , developers in recent years with the declining cost of HD Camcorders , HD camcorder prices gradually , "the people ", but its " HD " concept is compromised ? Some cheap HD network camera can achieve high targets ? HD network camera HD Concept What are the factors ? This article will discuss with you .
What is " HD" camera , HD camcorder is the first use of the concept in the field of radio and television , most people in the field of video surveillance or follow the broadcast television standard , the " HD" is defined as 720p (1280 × 720, progressive scan ), 1080i (1920 × 1080, interlaced scan) and 1080p (1920 × 1080, progressive scan ) video image resolution above .
"HD" can not just rely on the image sensor
A IP Camera mainly by the image sensor chip , the synchronization signal generator, as an image signal processor (ISP, imagesignalprocessor) of DSP, CDS / AGC chip shot several components , network cameras also have video encoding and compression chip . Webcams in the core components of the image sensor (ImageSensor) classification do so, there are both CCD and CMOS . It is through the CMOS / CCD light sensor for progressive or interlaced scanning , the optical signal is able to capture images directly and through SoC chip processing for transmission over an IP network , enabling users to standard IP-based network infrastructure on a local or remote location achieve viewing , storage and management of high definition video data. Market, many people are affected by the sensor as a core element definition , it is not.
Currently many manufacturers in promoting their own " megapixels ", " 3,000,000 pixels " or even "500 -megapixel " cameras, in fact, " megapixels " does not refer to the camera's video resolution , it simply means that the camera image sensor photosensitive number . In evaluating a section definition network camera's image clarity , in addition to pay attention to the image sensor of the " total pixels ", the more critical it is to see whether the output image resolution up to "HD " standard , which will affect the output image clarity is not only the number of pixels of the image sensor .
Network HD cameras now on the market there are many factors that affect the price , there are many high-definition video camera to the core components of the image sensor (ImageSensor) was once considered a high-definition camcorder HD indicators affecting only factor . But megapixels image sensor if the use interlaced mode , the image quality is also lower than 720p image sharpness .
HD network camera in recent years with widespread application of high-definition camera effects , in addition to key image sensor , the camera lens and an image signal processor chip , the camera of the " HD" plays an important role to achieve synchronization signal generating also affect the circuit of the camera scanning format .
HD lens prices fall cheap camera is expected to achieve high
HD IP Camera market now there are many factors that affect the price , there are many . HD cameras are now a part of the price of the most important is probably the lens. A good shot from a great extent determines the quality of theHD IP Camera , so now more and more people will be very concerned about high-definition camera lens , a clear lens, allows us to be more clear video picture .
As if the camera 's eye lens , and HD lens is like a piercing eye of the camera clarity is assured. As enterprises increasingly HD lens research and development efforts to increase its clarity, transparency, color reproduction and other aspects of better performance. Meanwhile various lens manufacturers for security monitoring industry launched HD lens product line has more comprehensive, private security market demand and government -led Safe City and other large projects to promote high-definition camera market to grow steadily.
With one million high-definition network camera applications increases, one million high-definition camera application is also accelerating pace . HD lens burgeoned have already begun . Beginning last year , the majority of security companies HD lens shipments increased significantly. This year, the prices have come down HD camera , HD lenses became part of the security companies is another selling point. As a result, the high-definition network camera lens selection more diverse, select the appropriate lens to achieve " high definition" promising. But the price is too low to ensure the camera lens is difficult to achieve high targets.

Analysis of high-definition IP Camera solutions
Analysis of high-definition IP Camera solutions
In recent years , network camera continue to impact the market, as the market increasingly high demand , there is a growing concern for high-definition network camera solutions , Texas Instruments (TI), Hass (HiSilicon), Ambarella (Ambarella), NXP Philips (NXP), l step (GrainMedia), Nextchip What are the characteristics in the end , the following small series will take you under them.
Currently on the market there are basically high-definition IP Camera solution three architectures :
The first category is the use of high-end camera modules ( movement, such as ACUTE the PE1005, SONY 's H11) as the image capture device , supporting an ASIC or DSP for encoding and transmission, such programs is relatively high , the use of professional imaging module , the original image is good, so the whole effect is very IPC products depends largely on the effect of supporting compression and transmission module , the main indicator is the compressed image clarity and timeliness , generally , a high-end program uses this architecture ;
The second category is the use of high-end camera module as part of image acquisition , and then supporting an ASIC or DSP for encoding and transmission, such analogies are operational and the first part of more such lenses can freely mix your own , you can also customize some special features to the product value. Imaging effect of such programs is very good, in the back-end compression and transmission is also not too many requirements. Very suitable mastered the network compression and transmission technologies are required but the effect on the image of the vendors use .
The third category is the use of CMOS sensor (SENSOR) as the image acquisition device , supporting the provision of ISP SOC chip , such programs have significant cost advantages , the main effect of such programs depends on the imaging chip maker Integrated ISP ( such as 3A, wide dynamic , etc. ) effects ; there is a more obvious advantage of such programs is relatively flexible and can be customized according to the characteristics of programs , such as capture, oversized low frame rate video.
For high-definition network camera , the network protocol and the SDK is a very important aspect , each company has its own network protocol and SDK, and basically dedicated exclusively . That each network camera are incompatible , not interchangeable , if we adopt the way outsourcing module is a big trouble in this regard , including system integration, customer care , and this will bring a big problem. HD IP Camera combines the core of the current security industry 's most cutting-edge technologies and applications : networking, HD and intelligent , but also the integration of the necessary conditions.
1 Based Module + SOC (DSP) application program
Currently advantage of such programs is the image effect is good , generally comes with the lens. Network compression module now supports 1080P TI's current main DM6467 and DM368, Maxim 's MG3500, Fullhan microelectronics FH8735, Fujitsu MB86H56, NXP 's PNX1005, Hass 's Hi3516/20 so on. DSP-based architecture which do have intelligent analysis DM6467 and PNX1005 , etc., each have their own advantages and disadvantages. Where TI is the leader in this industry , so TI is also relatively high. The advantage of such programs is the image better, difficult to develop relatively small drawback is that the lens curing , not according to their own requirements using the lens , which is developing and supporting the freedom of small projects , is the first choice for high-end customers .
2 Based BoardCamera + SOC (DSP) application program
Such programs appear on the market today there are more and Hass Hi3516 TI , etc., this program will fit mastered the network compression and transmission technology and relatively high demand for image used by customers and isp front sensor has been integrated , color reduction and low-light areas such indicators are handled very excellent example Division I PE0003 module very well and DM368, HI3616 programs such cooperation. Customer-proven , image effect is very good . Excellent image quality of such programs , developing large degree of freedom , based on customer requirements, characteristics to be customized and optional lenses.
3 Based SENSOR + SOC (DSP) application program
Such programs appear on the market today there are more and Ambarella TI , and also the current HD machines largest shipments , the market price is very confusing, there are ridiculously low low , high and surprisingly high . The advantage of such programs is low cost development is easy, and it's basically a fight can be used ; drawback is that the image quality is not good with the module or modules ( depending on the chip provided by ISP).
In recent years , network camera continue to impact the market, as the market increasingly high demand , there is a growing concern for high-definition network camera solutions , Texas Instruments (TI), Hass (HiSilicon), Ambarella (Ambarella), NXP Philips (NXP), l step (GrainMedia), Nextchip What are the characteristics in the end , the following small series will take you under them.
Currently on the market there are basically high-definition IP Camera solution three architectures :
The first category is the use of high-end camera modules ( movement, such as ACUTE the PE1005, SONY 's H11) as the image capture device , supporting an ASIC or DSP for encoding and transmission, such programs is relatively high , the use of professional imaging module , the original image is good, so the whole effect is very IPC products depends largely on the effect of supporting compression and transmission module , the main indicator is the compressed image clarity and timeliness , generally , a high-end program uses this architecture ;
The second category is the use of high-end camera module as part of image acquisition , and then supporting an ASIC or DSP for encoding and transmission, such analogies are operational and the first part of more such lenses can freely mix your own , you can also customize some special features to the product value. Imaging effect of such programs is very good, in the back-end compression and transmission is also not too many requirements. Very suitable mastered the network compression and transmission technologies are required but the effect on the image of the vendors use .
The third category is the use of CMOS sensor (SENSOR) as the image acquisition device , supporting the provision of ISP SOC chip , such programs have significant cost advantages , the main effect of such programs depends on the imaging chip maker Integrated ISP ( such as 3A, wide dynamic , etc. ) effects ; there is a more obvious advantage of such programs is relatively flexible and can be customized according to the characteristics of programs , such as capture, oversized low frame rate video.
For high-definition network camera , the network protocol and the SDK is a very important aspect , each company has its own network protocol and SDK, and basically dedicated exclusively . That each network camera are incompatible , not interchangeable , if we adopt the way outsourcing module is a big trouble in this regard , including system integration, customer care , and this will bring a big problem. HD IP Camera combines the core of the current security industry 's most cutting-edge technologies and applications : networking, HD and intelligent , but also the integration of the necessary conditions.

Analyze IP Camera problems faced by low-end market penetration
Analyze IP Camera problems faced by low-end market penetration
Currently, the Network Camera in the low- security market has begun to spread , but the main faces several practical problems .
First, the network delay and compatibility issues
As early as the previous network camera delay , instability caused the illusion to the user , the current compatibility is the fastest network monitoring needs to fix things .
Second, the network bandwidth limitations
The popularity of IP Camera Another constraint is the problem of network bandwidth , network cameras capture the dynamic image , and only in one second can upload and download at 135K or more in order to ensure its smooth transfer images without stutter tail, but China the current home network speed far worse .
Network camera does not really seem optimistic about a bright future , which requires manufacturers , government, network operators, the three complement each other in order to be changed.
Third, the ease of use of the product
Common products such as security cameras installation has professional installers, while ordinary camera network camera is the integration of new technologies and IP Camera technology and its working principle is to monitor the use of the network spread to the image anywhere on the network , regardless of the body in where the world , just in the browser will be able to view the monitor screen . Network Camera This application requires users to install and commissioning , he must set up the network and the computer have some grasp. Ease of use and simplification of popularizing the first question . This solution will be more people use .
Fourth, network monitoring is difficult to control the cost of storage
In the field of video surveillance , the cost issue has been back-end storage can not be ignored . When the network is monitored gradually spread to the home user, the front-end equipment spending perhaps price tag, but this back-end disk storage costs is really unmanageable . Especially for megapixels Network Camera surveillance for high-definition , high-definition picture quality and portable storage can not have both . Users do not have the requirements for image quality is not the same , resulting in storage space and storage equipment investment is not the same . When will the entire monitoring system controllable costs to be truthful , then the popularity of high-definition products for the network seems to be highly anticipated .

IP HD CMOS sensor is the mainstream technology trends
IP HD CMOS sensor is the mainstream technology trends
HD IP Camera with CMOS sensor and application of technology to enhance increased , HD IP Camera will be more approachable price , HD IP Camera will gradually replace analog and SD cameras households.
HD IP Camera one of the core components of the sensor , the second is Soc processing chip. CMOS sensor The main problem is how to continue to improve low-light , wide dynamic effects , Soc processing chip main problem is how to continue to increase processing capacity , providing higher, faster , better information .
IP Network HD high definition cameras advantages , ease of use , not overlooked , etc., is the mainstream trend products ; disadvantage is the price is still high , the product has not yet fully spread, market acceptance of the inherent need to continue to improve .
HD-SDI HD Camcorder advantage of uncompressed , real-time transmission , enclosed safety and other aspects ; disadvantage is the high cost of wiring trouble, vulnerable to interference , transmission distance is limited , but the transitional product .
Currently , HD IP Camera proportion is not great, there is much room for development , prospects are very promising , the specific share of bad estimates.
HD HD-SDI and network will exist within a certain time . HD-SDI network HD due to technological developments than a couple of years later , facilities can not keep up , the price will be high cost . However, due to the continuation of the analog HD-SDI monitor the conventional thinking , from a user perspective, acceptance is relatively high. The Network camera with the construction of large projects around , Security Exhibition on the popularity of network monitoring , have gradually been known users , and based on the actual application, network products compared to high-definition HD-SDI products also have certain advantages. However, the trend of the future must be a network HD , and the current network HD and HD-SDI HD both have their own market , and perhaps the future will be popular in the network while adding high-definition HD-SDI interface.
HD Network camera from 2010 is still in the marketing period , with the Shanghai World Expo and Guangzhou Asian Games , Safe City and other large projects on the network HD product applications , network HD past two years the market growth rate of 30 % or more. This also shows that the overall effect of the network definition and solutions have been accepted by users . And with HD technology gradually matured Network HD product illumination , the bandwidth problem has been well improved , the cost is a downward trend, it can be said , HD is gradually on the right track , analog to HD is an irreversible trend .
Network HD front advantage lies in its high-definition monitoring results , a simple and convenient system wiring obviates the cumbersome construction , through remote monitoring and manipulation has certain advantages. As for the choice of HD products in the network depends on the actual needs of the user , the estimated cost of the project , subject to different choices, but the minimum entry threshold is 720P monitoring results. In small projects can make use of the existing network , equipped with high-definition systems, relatively inexpensive relative choice ; monitoring in a large network , mainly taking into account the practicality front , scene selection , you also need a dedicated network , so security and reliability in order to get a certain guarantee that this definition of network products, integrated high performance requirements .
In a large high-definition video surveillance network , the video card frame transmission phenomenon appears inevitable . There are two reasons : First, the transmission cable quality problems ; Second, network data transmission technology itself flawed. Some contractors in order to save costs, without taking into account the cost of the cable to the entire video surveillance system impact to facilitate the weight . The cable multiple cascade , will also affect high-definition video transmission. HD products such as general network latency test results within 200ms , but the practical application latency was much higher , which is closely related to the cable . Current transmitted through the fiber is a good solution , the light transmission in the anti-jamming capability and transmission efficiency should be stronger than the network cable , high-definition video transmission ensures good stability . Network problems are often their own stuff phenomenon, which can not be avoided , in order to ensure the integrity of high-definition video , the current practice of most manufacturers is through the front of the video in real-time stored.
Relevant departments to increase the bandwidth requirements of domestic construction , and gradually realize FTTH, the current 2-3M bandwidth increased to an average of more than 10M . The carrier added and investment , on the development of FTTH has some impetus to the popularity of the network HD is a good news. For manufacturers, the use of advanced compression technology to the codec , the higher the compression ratio , taking up less bandwidth , plus the added value of intelligent front-end , a smart bit rate compression using dual-stream and multi-code streaming technology to reduce bandwidth transmission rate , our camera is used in multi-stream technology that can better adapt to different network environments.
Currently, many users believe that the traditional front-end HD Network camera with a large gap between the price of analog cameras , HD front too expensive. But in fact, from the whole of the starting solution , the network has the advantage of a relatively high cost . For example, 16 -channel analog surveillance system with 16-channel high-definition network video surveillance system solutions comparison: front-end monitoring probes, coaxial cable construction, back-end storage devices, display devices to set the desired cost and network HD program was essentially flat. In recent years the cost is reduced network HD , back-end storage solutions , application solutions and gradually improve , I believe that the cost will no longer be a constraint to the development of the main factors of network HD .
Intelligent video analysis is mainly front-end and back-end platform for smart camera video analysis technology , mainly in the massive piece of information retrieval , which requires a certain degree of optimization of the back-end platform . The current situation is the user feedback network HD storage capacity , video information retrieval is very complicated, ten thousand hours of video may be useful also ten minutes , the traditional art search is very troublesome . At present, some mainstream manufacturers approach is through the info key scenes , behavioral analysis to analyze retrieval , specifically face recognition , license plate search, behavioral analysis, intrusion prevention , anti- displacement and other items retrieved , reducing time video retrieval . However , this requires front-end and back-end Network camera can be achieved with the platform .

IP Camera intelligent analysis simulation system by pre- DVR
IP Camera intelligent analysis simulation system by pre- DVR
Known network surveillance camera comes with intelligent analysis, video analysis will lead to the front end devices, faced with an emergency alarm function can be the first to respond . And network probe is different, analog cameras through the backend DVR determine whether the illegal invasion behavior. Targeted at two different authors make a comparative analysis .
In the video surveillance system, analog cameras seems to give a kind of " integration " feeling , cameras and sensors and other components are wrapped in a small space , if you want to change a different focal length of the camera , probably have to " disassemble " Replacement ; the network camera lens and machine identity to leave, different focal length lens replacement is very convenient.
Then we say that the appearance of the core network surveillance cameras have been able to support video analysis function, the reason is that open platform . With the camera chip performance increases , there will be more chip resources are being developed, so that more intelligent analysis of IT elements embedded into the front-end devices, but also allow more third-party software is compatible with video analysis , to select multiple intelligences .
Webcams intelligent analysis simulation system by pre- DVR
Simulation system is a closed structure, the current terminal equipment can not meet , they can only be transferred to the back-end intelligence analysis capabilities DVR storage system , based on the embedded Linux system DVR the same as the open-source structure can be implanted in a different mode of analysis , through the video will be transmitted to the front-end integration and analysis.
Front-end and back-end analysis of comparative analysis of the time
Front-end Network Camera supports intelligent analysis , simulation system for the back-end analysis, one before and one after the contrast in theory be able to separate the order. In the front can make the appropriate intelligent analysis , just put analyze the results of treatment can be spread to the back-end platform ; while the back-end analysis needs to be spread throughout the DVR video images , and then have spread to resolve DVR platform , although the processing speed quickly, but will inevitably cause some of the time difference .
Maybe in a small monitoring projects, insufficient backend intelligence analysis as " inferior " , but in the important financial areas or large-scale monitoring , the race against the significance came to the fore .
Intelligent Network Camera Support SD card storage of pre-
Turning to the merits , in fact, both have equal shares . In the design , IP Camera must support intelligent front end storage capabilities. Maybe someone in coursing , IPC supports SD card memory can save a back-end storage fee. In fact, this view is wrong , SD card storage solution is only a secondary role : network failure , end alarm when needed SD card storage ; but its drawback is that is not conducive to a wide range of video management .
Intelligent analysis and detection Network Camera
Front storage space is limited, so the codec requirements are very stringent. I 've learned in the H.264 codec in , High profile main application and network systems , most of the DVR video recorder also uses standard Main profile . Unzip the different patterns also reflect the effect of the final image generation .
Simulation system intelligent analysis " rear " to ensure the stability of the system , compared with the pre- IP system intelligence for emergencies lag really have an impact . According to different application areas choose a different trigger modes. Difficult to weigh the pros and cons of the case , SD card storage can go long , the future analog cameras can embed intelligent modules , which are still unknown .

Simulation system is a closed structure, the current terminal equipment can not meet , they can only be transferred to the back-end intelligence analysis capabilities DVR storage system , based on the embedded Linux system DVR the same as the open-source structure can be implanted in a different mode of analysis , through the video will be transmitted to the front-end integration and analysis.
Front-end and back-end analysis of comparative analysis of the time
Front-end Network Camera supports intelligent analysis , simulation system for the back-end analysis, one before and one after the contrast in theory be able to separate the order. In the front can make the appropriate intelligent analysis , just put analyze the results of treatment can be spread to the back-end platform ; while the back-end analysis needs to be spread throughout the DVR video images , and then have spread to resolve DVR platform , although the processing speed quickly, but will inevitably cause some of the time difference .
Maybe in a small monitoring projects, insufficient backend intelligence analysis as " inferior " , but in the important financial areas or large-scale monitoring , the race against the significance came to the fore .
Intelligent Network Camera Support SD card storage of pre-
Turning to the merits , in fact, both have equal shares . In the design , IP Camera must support intelligent front end storage capabilities. Maybe someone in coursing , IPC supports SD card memory can save a back-end storage fee. In fact, this view is wrong , SD card storage solution is only a secondary role : network failure , end alarm when needed SD card storage ; but its drawback is that is not conducive to a wide range of video management .
Intelligent analysis and detection Network Camera
Front storage space is limited, so the codec requirements are very stringent. I 've learned in the H.264 codec in , High profile main application and network systems , most of the DVR video recorder also uses standard Main profile . Unzip the different patterns also reflect the effect of the final image generation .
Simulation system intelligent analysis " rear " to ensure the stability of the system , compared with the pre- IP system intelligence for emergencies lag really have an impact . According to different application areas choose a different trigger modes. Difficult to weigh the pros and cons of the case , SD card storage can go long , the future analog cameras can embed intelligent modules , which are still unknown .
