HD IP Camera to protect the residents
HD IP Camera is now basically in the major streets or inside each cell can be seen because of its convenience and performance of diverse, been applied in their lives where it is more and more, precisely because it was area residents make our lives more comfortable happy.
Living in the area, installing a high-definition IP Camera is very necessary, it's like living in a third party, which saw a lot of things we can not see, with it can be a good monitor every move of the cell, and if What can be found in people or things can be found in a timely manner, and get timely treatment, but it also changed the traditional way of doing things simply rely on manpower. Imagine if there is no district Zhezhi third pair of eyes, then our lives what changes will happen, that's serious point, what happens if the accident is no strong evidence and restore the ability of the facts, it is the biggest advantage the fact is that we can restore a lot of things though once passed over, but there it can be a very good thing for the development of dynamic monitoring down to find a favorable first-hand information.
In the modern inhabitants of life, the role of network camera is more and more obvious, many industries are also inseparable from the existence of HD IP Camera, because it was better to protect the living.

HD IP Camera monitoring the importance of safety on campus
HD IP Camera monitoring the importance of safety on campus
Universities which essentially adult population, external intrusion, the campus has its own internal security is important, but its security extension application is already occupied by the proportion of heavier focus on this aspect is reflected in the application of distance learning.
HD surveillance system applications on campus
Superior network environment: modern campus on their own network planning requirements are very high. Gigabit backbone, Gigabit to the desktop, the campus network environment abound, good network environment to an IP network video surveillance system provides an excellent basis for the link.
Flexible expansion: Combining the specific business needs of colleges and universities, the school hopes to make play a video surveillance system in addition to security, after the evidence of the role, it can also be used for other purposes, such as electronic monitoring, remote education. From a long-term perspective, the future will continue to university enrollment, along with the growing expansion of student density, which will inevitably lead to a lot of places becoming blind spot monitoring. This time we need to be more flexible extended monitoring points, while the IP network surveillance cameras just have such a capability.
For details of the training, so that children have the opportunity to escape command
This emergency response mechanism is reasonable place is also reflected in some of the details. First, the mechanism for the parties to create a complete emergency crisis response communication, a unified term crisis response system to ensure that school staff who deal with the crisis consistent with the terminology, so that all kinds of school personnel are able to understand the underlying barrier commands.
"New Yorker" has described this year on February 27 Ohio Schaden secondary school shootings across the scene: "The kids in the restaurant running and shouting 'a guard'! Some people hiding in the teacher lounge ; they used the piano to withstand door was also open the school's public address system to tell you how to do, but we all know how to do The students ran into the classroom, hiding under the desk; teachers locked the door, shut the Lights. "kids call" a guard "is a response to school shootings crisis terminology.
Secondly, the mechanism will be set up a variety of internal and external communication approach. Crisis occurs, the computer, the internal communication system, telephone, and even mobile phones may not work properly, so you should set the mode of communication as much as possible, to ensure that schools have more adequate communication facilities, stakeholders can easily access to similar facilities; guarantee school crisis response communication facilities and compatible communications devices sector will not affect or interfere with crisis response department communication device. The Connecticut shootings, open it achieved a lot of radio, school staff learned timely seriousness of the situation, which led the central area of the student is not in danger of self-help organizations.
HD Video: Due to wear in school, age, body relatively close, it is difficult to distinguish from the clothing on the body; classroom system also plays a security guard, electronic, distance learning and other functions. In addition, the university's population density is relatively high, its playgrounds, squares wide, so the clarity of the video surveillance on campus increasingly high demand, and the current megapixels digital video has gradually matured, 1.3 million-pixel high-definition digital network Camera is not a fresh product.
Relatively quiet campus generally located in remote areas, there was not much around the flow of people and vehicles, and the students' self-protection and self-discipline than the poor, therefore, outside the security perimeter intrusion is particularly important. When the infrared beam alarm system detects moving objects crossing the perimeter, an alarm signal is issued at this time, the control room can be learned through this alarm signal if there is an object invasion. Surveillance cameras inside the perimeter to prevent play a video review of the role of the limitations of infrared radiation is high false alarm rate, while the video review is to reduce false positives, reduce workload and improve work efficiency and effective means. HD IP Camera video to a large extent ensured composite video, intelligent analysis accuracy.

IP network camera application advantages destabilize industrial cameras
IP network camera application advantages destabilize industrial cameras
Industrial machine vision cameras are used to monitor product quality and production process of the control. According to a recent market survey indicates, network cameras also known as IP Camera, surveillance cameras and Industry has no small difference, today we have to sum up, the network camera applications and benefits.
Typical features of network camera
Webcams delicate sense of rich image quality, in full compliance with the human visual sensory needs, in addition to use of the network allows data storage for longer, of course, all of the video data through efficient compression, reducing video storage space, but also reduces the required video transmission bandwidth overhead. Taking into account the cost of construction, IP Camera can work in low network bandwidth, but also benefit from this advantage, multiple IP cameras can be run within the same network.
Can destabilize application advantages of industrial cameras IP cameras
In short, the network camera image data compression has the advantage of requiring less bandwidth and storage space required can be stored daily video image information. Will bring to the monitoring system and the hardware too much trouble.
Another major advantage of the network camera: simple operation. Once the IP Camera is connected to a particular network, any computer on the network can access the camera's IP address, browse to the cameras to capture images. Easy to install and manage the surveillance cameras.
For industrial surveillance cameras, the configuration extensive network cameras is relatively simple, but for special areas of application equipment on the slightly complicated. Image perspective and focus needs to be written to the new program.
Power engineering surveillance cameras
HD IP Camera can be effectively used anywhere, such as monitoring the production process or the automatic machining line manual processing and packaging. Especially for those who need high-definition images of places, although light, weather or temperature of these places have a strong interference. Of course, IP Camera and storage capacity is needed most industrial monitoring.
Network camera ideal for use
From a technical point of view performance, HD IP Camera is the ideal choice for monitoring. This range includes traditional video surveillance, burglar alarm, and control production processes and workflow, or traffic monitoring. Did you know, IP cameras are also very suitable for remote machinery remote control, such as cars and robots. Of course, this is an ordinary video surveillance has different forms:
Surveillance cameras to monitor the system provides a good basis for the image, despite being monitored environment variable and weak light conditions. For example, some foreign casinos relatively dim light, but was exceptionally strict security system. Like banks, like here, the daily ten million yuan water is very ordinary and simple.
Broadcast cameras
Traffic surveillance cameras often subject to interference outdoor conditions, which means that the camera must be able to automatically adjust the lighting conditions to ensure that capture angle. It is also necessary to have a strong handle outdoor hot work and monitor the issue of water vapor.
In the monitoring system, not all applications are only a surveillance camera at work. Observers in the control room can manipulate multiple network cameras check road conditions and road traffic impact on the road. Also in order to avoid violence, sorting, courier industry is also fitted with surveillance cameras to standardize logistics and transport process. Network camera is particularly suitable for the logistics and transport sector, because they are easy to integrate into existing video management system.
When the monitoring system encounters suffering tunnel access points, or in extreme weather conditions, or away from the control center, the network surveillance cameras can be equipped with wireless transmission mode, in the absence of local PC case also be able to view video images. IP Camera image compression technology to better store image data, for a variety of possible hidden to provide the necessary "proof", especially for monitoring road traffic offense or a football game, network cameras contributed.

"HD" and "millions" of watershed gradually borrow
"HD" and "millions" of watershed gradually borrow
Since last year, domestic production standards megapixels IP Camera missing, megapixels network camera market appears 720P, 1080P, 130 million pixels, 2000000 pixels, etc. coexistence. As the manufacturers have developed to the SMPTE HDTV standards closer, which is commonly known domestic manufacturers to achieve 720P, 1080P resolution, and possessed a 16:9 display mode and full frame rate. "True HD" concept is gradually perceived as more and more people. "1300000 = 720P", "200 万 = 1080P" These common sense in popularity during the marketing of high-definition explains expediency has gradually been forgotten.
From this year the domestic market each megapixels network camera using proportionate pie chart we can see that in 2011 domestic megapixels network camera application is mainstream 720P, 1080P resolution HD camera-based, using the proportion of its market about megapixels network camera for 91% of the overall market size, growth rate using the same proportion increased by approximately 40% compared to last year. To 1,300,000, 2,000,000, etc. as the representative of megapixels network camera, its use increased from last year, about megapixels network camera for 51% of the overall market size, down to 7% this year, a decrease of 44%. And with 3 million pixels or more as the representative of "super HD" network camera, this year's market use ratio of about megapixels webcam 2% of the overall market size, a slight increase compared to last year; data from the graph can be seen megapixels network camera transition to HD IP Camera was evident. It can be said, in the future we are talking about megapixels network camera will mean 3,000,000 pixels or more products, 1.3 million pixels, 2-megapixel product will be replaced by the standard definition products.
From 2011 to megapixels network camera main application industries histogram can be clearly seen, "Green City" Like last year, is still up to the application megapixels network camera industry, its application accounted for approximately 43.7%, with Compared to last year rose to 3.7%. However, application of the industry last year, the proportion of about 26%, ranking second in the "factory", accounted for approximately 31.2% of applications this year than last year rose 5.2 percent, ranked second in their application to be "intelligent transportation" won, placing him first III. It is worth mentioning also the application of intelligent transportation industry, the industry accounted for only 14% of last year's application, while the application of a high proportion of this year's 40.6 percent, or about 26.6 percent, the proportion of applications ranked second. While other industries including public prosecutors, law, prison systems, schools, and financial industries, the proportion of its last application are also less than 10% of the market this year, however, has a substantial industry application growth, including public prosecutors, law, prison system applications accounted for approximately 28.1%, the financial sector accounted for approximately 25% of applications. Overall, megapixels network camera application industry little change in the top three.
Megapixels network camera in order to bring high-definition picture quality at the same time, its applications are quietly changing. With high-definition network camera megapixels network camera's position highlights, HD IP Camera and megapixels network camera (refer to 3 million pixels or more products) in the application of the division has become more apparent. It is understood that the current domestic applications megapixel network camera (refer to 3 million pixels or more products) are more largely peaceful city traffic bayonet and intelligent transportation freeway ramp, etc.; while high-definition network camera application is more safe the city's urban road monitoring, intelligent transportation, such as airport / port, border security, etc., factories, finance, schools, and public prosecutors, law, prisons and other fields.
With the promotion of safe city, relevant industry application market is also developing rapidly. Currently addition to traditional transportation, factories, financial and other industrial applications, many industries are in high-definition network video surveillance applications. HD picture quality to bring people face an unprecedented visual experience, making HD IP Camera video surveillance not only stay in the security field, is no longer in the application of industrial customers enterprise-class, HD Network Camera gradually moving towards the civilian market trends increasingly prominent.
"Right now the market megapixels IP Camera applications of view, high-definition network cameras are mainly used in corporate factories, transport sector airports, ports and other industries, as customers increased demand for high-definition, HD IP Camera is very likely future will be applied to retail shops, building construction and other industries. "
"With megapixels network cameras increasingly high-resolution,HD Network Camera popularization and development, its application will not only be limited to the security industry, but also the application of commercial marketing," It is understood that the current domestic chain hotels, shops and other commercial real estate industry's increasing demand for video surveillance and video surveillance in HD on demand is quite high. From the article 2011 megapixels network camera main application industries histogram can be clearly seen that year, real estate, hotels, shops and other industries, the proportion of high-definition IP Camera applications is about 18%, compared with last year, market applications, Applications range has been greatly improved.
While the price for the civilian market is quite concerned about the characteristics of many network cameramanufacturers have begun to launch more cost-effective products. Of course, due to the network camera installation and operation is more complex features, how to create a front end to the back-end system can achieve high definition, as well as how to easily setup and installation will be the first high-definition into the civilian market issues to be addressed

Detailed analysis of Network Cameras stream processing technology
Detailed analysis of Network Cameras stream processing technology
Network infrastructure, network video surveillance market environment is an important factor in good development. At present, the network video surveillance market, the lack of good network infrastructure environments, making the network video surveillance, especially in high-definition network video applications subject to certain obstacles.
HD IP Camera in image sharpness on a qualitative leap, but also to the network monitoring system has brought a series of questions:
· Network bandwidth tension: the greater the resolution, high resolution, the transmission stream will increase, increasing the network bandwidth pressure;
• Storage space: data traffic doubled, increasing the storage capacity, increasing the pressure on network storage;
· Management platform software and hardware load increased;
· Construction costs doubled.
Therefore, in the pursuit of high quality, while the network video surveillance equipment manufacturers proposed to solve the above problems requirements. Therefore, the need for video stream processing and control technologies to be constantly developed to cope with HD brings high-bandwidth, high-capacity storage and other issues.
Video compression technology
In the field of video surveillance, video compression encoding format from the M-JPEG, H.263, MPEG4 to H.264 development, H.264 compression algorithm is a mainstream application. Its biggest advantage is a very high data compression ratio, the image quality in the same conditions, H.264 compression ratio is 1.5-2 times of MPEG-4. H.264 with a high compression ratio also has a smooth high-quality images, and as such, H.264 compressed video data through the network during the transmission bandwidth required less, and more economical, saves Users download time and data traffic.
Technically, H.264 focused on the advantages of the previous standards, standards development and absorb the experience gained. And H.263, MPEG4 compared, H.264 did significantly reduce the bit rate up to 50% savings rate, effective implementation of the code flow control. Now there are more manufacturers of network video products using advanced H.264 compression algorithm.
Stream processing technology analysis
Even with advanced H.264 compression algorithm, HD 720P also need 3-4M bit stream, HD 1080P also need 4-6M code stream, still remain unresolved network, storage pressure and other issues, so there is a variety of streams treatment.
Streaming mode selection function
Network Camera generally transmit audio and video streaming, but support stream selectable modes, namely: audio and video streaming, pure video streaming, but also the camera supports audio-streaming mode. In accordance with the different audio and video needs, select the appropriate flow pattern, can greatly ease the pressure on the network, the storage pressure to reduce investment costs.
Variety of coding techniques
HD IP Camera supports three more are encoding technology, which is to support JPEG/MPEG-4/H.264 three different compression formats, can be set according to the actual situation of our customers three streams. For example: the lower stream D1 H.264 video compression format image transmitted to the remote real-time monitoring to the customer, while the megapixels H.264 video compression format incoming real-time image storage server for video, another You can also transfer megapixels alarm when a JPEG image, easy to zoom afterwards confirmed, looking for suspicious objects. With the application of a variety of coding techniques, also relieve pressure on the network to solve the storage problem of pressure. Dual-stream processing technology
Dual-stream, that coexist two kinds of IP Camera streams. Dual-stream by the encoding side using the two formats are encoded to achieve. One kind of stream for network transmission, and another stream for high-quality real-time storage, dual-stream taking into account the local storage and remote network transmission, to solve the bottleneck of network transmission. Dual-stream implementation for local storage lift start a new one. Were coded separately stored, according to the network bandwidth flexibility to choose the stream size, so that the local HD storage and low stream transmission coexistence possible.
Multi-stream processing technology
With respect to dual-stream, multi-stream on stream output provides multiple independent choices, respectively, through multiple clients to access the camera pre-set multiple streams. Such as: 3,000,000 (15 frames / sec), 1080P (25 frames / sec), 720P (25 frames / sec) and D1 (25 frames / sec), and each client can receive a preset synchronization stream. The technique is to achieve a variety of applications in the environment, the camera can provide multiple, independent streams through the selection, and can also reduce network load and stress. Such as storage with 300 million, the local client access with 1080P, TV wall display 720P, remote client access with D1, while the mobile phone user to select CIF or QCIF resolution and other smaller, has no effect on each other and can transmit simultaneously . Thus, it avoids the Network Camera is only one choice, both to meet the needs of high-definition monitor, also saves storage space.
Currently various manufacturers for multi-stream processing technology differently. Such as support for multiple concurrent streams, but these must be the same video stream configuration parameters, modify any way stream configuration parameters, such as resolution, frame rate, etc., then all the other stream configurations will change, which can not be truly multi-stream control. True multi-stream technology, multiple streams are completely independent configurations can be respectively different resolutions, different frame, different compression ratios or different encoding, at the same time, the performance of the multi-stream Support for multiple concurrent full resolution, full frame rate independent concurrent streams. Industry, manufacturers of network video products have been having the multi-stream processing technology alone.
Flow control mechanism
For IP Camera, multi-stream processing, the configured independently for each video stream, to achieve good flow control mechanism in the application also plays a very important role. Stream Control includes variable stream, a constant stream and the maximum current limit mode.
· Variable stream to maintain the set of the video configuration parameters such as resolution, frame rate, etc., the video stream bit rate changes as the video content fluctuations;
· Maintaining video stream at a constant bit rate, and the image quality, and as the video stream will be adjusted for changes in the content. Users can also maintain a constant bit rate case, select the image quality or frame rate priority priority;
· Maximum flow limit is allowed bit rate of the video stream to the fluctuation, setting the maximum threshold limitation, when the bit rate is limited to the maximum threshold, the video quality will be reduced accordingly to maintain the video stream does not exceed set maximum threshold.
Seen, for true multi-stream technology provides a good chip processing support, and can provide a variety of sound corresponding flow control management mechanisms in order to ensure network video products in actual use, availability, and real rationalization for Internet video streaming management, so that better meet the needs of practical applications.
Epilogue
In short, do a better stream processing and control, solve network, storage and other stress issues in order to better meet the definition network video surveillance actually need. Right now. Some manufacturers of network video products security applications H.264 compression algorithm and multi-stream processing technology is relatively mature, and its network video products have been capable of performing large-scale HD IP Camera video surveillance system needs, and overall customer input costs reduced, while advanced technology will promote high-definition network video surveillance security industry more large-scale application.

A webcam is a combination of traditional cameras and network technology produced a new generation of cameras, it can be transmitted through the network image side of the globe, and the remote surfers without any professional software, just a standard web browser (If "Microsoft IE or Netscape) to monitor its image. Network Camera as an embedded chip, embedded real-time operating system.
In addition to providing high-speed broadband information network network access outside the image can replace copper coaxial cable transmission line, real-time video surveillance applications include broadband information network, which makes the information network instead of the traditional CCTV become inevitable. Multimedia PC-based monitoring system powerful, but mainly for small-scale monitoring. When the transmission distance or need to access the Internet, the PC-based multimedia surveillance stability is not good enough, high power consumption, the need was on duty, the openness of the software is not good. These issues of network-based and embedded network video surveillance technology provides the stage.
IP Camera converts the image to a TCP / IP network standard data packet, so that the camera captured images via RJ-45 Ethernet interface or WIFI WLAN wireless interface directly to the network, through the network to remotely monitor screen.

Buy network camera must understand the relevant knowledge
Currently the network camera video compression algorithm mainly includes: M-JPEG/MPEG4/H.264, H.264 places in the country for the mainstream, basically done MainProfile compression level, but different manufacturers in the details of the optimization algorithm on are different. Some manufacturers, such as the full launch of the full range of Megapixel IP cameras are using H.264 compression algorithm, can support 720P/1080p full frame rate HD video output. Image quality at the same time ensure quality, technical standards for H.264 compression coding efficiency were significantly improved and enhanced the amount of data after compression MPEG4 only 1/3, greatly reducing the transmission bandwidth and back-end storage pressure . And taking into account different network environments, H.264 compression algorithm can be based on different network environments using different transmission rates, and the ability to self-regulate bandwidth utilization, optimizing the network bandwidth resources, but also provide users with a more more practical application experience. In addition, HD Network Camera supports H.264/MJPEG/JPEG video encoding, supports dual-stream, the user can according to the actual application requirements, to carry video data multiplexing, enabling multi-application operating selectivity.
Comparative analysis of the SDI camera
In terms of quality SDI video cameras and HD Network Camera can achieve 720P/1080P level or even SDI cameras can also provide higher transmission frame rate, generally up to 30-60 frames / sec real-time image acquisition. And SDI cameras with high resolution images, higher resolution, richer color and other characteristics, to meet the user demand high-definition monitor. Currently, as a specialized market for high-end security monitoring equipment, SDI camera image quality on its excellent quality and system architecture is relatively simple features, so that in some special industries have better prospects.
But in low light, wide dynamic cameras and other basic functions, SDI cameras and HD IP Camera are there is room for improvement. Now SDI Camera with CCD imaging chip more more, CCD chip photographic performance is better than CMOS, relatively speaking, the monitoring results to be better at night. Existing HD image sensor light sensitivity are not ideal, at night in low light situations to capture the image less effective, therefore, effectively enhance the image sensor performance is critical. Besides increasing the illumination photosensitive chip performance, now also with the infrared technology, thermal imaging and other technologies to obtain the desired picture effect, so that the night monitoring the effect is improved, so that 24-hour monitoring more perfect, more efficient.
In addition, the most important is the camera SDI transmission distance is very limited, it can only transmit 100 meters. The network camera can be transmitted as long as relying on the network, which is the biggest difference. Moreover, due to front-end SDI cameras capture a large amount of data, the transmission process without warp codec compression, data storage presented to the great challenge. But the network HD camera uses H.264 compression algorithm that can save transmission bandwidth and storage space.
In summary, SDI cameras and HD camcorders have their own web applications and focus, they are complementary rather than substitute relationship. SDI Camera To get a larger application space, the transmission distance may be a bottleneck, so the need to break the transmission distance SDI cameras only continue to meet user needs, SDI cameras in order to have a broader development prospects. For network camera video compression algorithm re-optimization, there is both high quality low bit rate, is still the focus of its performance. Then, either SDI cameras, or network cameras (SD or HD), low-light, wide dynamic camera should have the basic need for both high performance for both continuous improvement.
Intelligent and more reliable backend
Intelligent network cameras now includes two solutions, one is in front of the camera at intelligent analysis, and the other one is in the back-end server to achieve intelligent analysis. Front-end analysis of the advantage of not requiring server support, can be applied individually, the disadvantage is the limited capacity of front-end chip processing, not suitable for complex, large workload analysis. Especially in some special applications or applications where a single function, such as traffic, traffic statistics, etc. Another example, often only need to analyze information and license plate counting, this time in front of the camera intelligent analysis applications, it can satisfy user monitoring requirements.
Taking into account various factors, some manufacturers gradually introduced a unique solution that is done in the back end analysis, analysis of the advantages of doing backend processing ability, and another advantage is more flexible, you can always opt for one front-end analysis or do not do analysis. If applied to large mall video surveillance cameras, the need for shopping areas, elevator, passageways, entrances, parking lots, warehouses and other places of real-time monitoring, since monitoring points are more often prone to the phenomenon of image information redundancy for this a problem, some manufacturers have chosen to do intelligence analysis on the backend server, the user can according to their needs, always select the front need to monitor key sites for monitoring intelligent analysis, makes the application very flexible, powerful processing capabilities and the server it is possible to cope with large amounts of data analysis, especially for end users of analog cameras, the more important. Existing analog cameras can be retained, just on the backend server embedded intelligent analysis module, thus saving tip replacement cost for the network HD cameras. Visible, backend intelligent solutions for their professional safe and reliable features, has been widely supported by the majority of industry users.
The main reason for the popularity of failed
At present, from our point of view the whole security industry, network camera also failed to gain popularity scale, mainly in the following three reasons. First, the technology is very mature with respect to traditional analog surveillance system already familiar with networking and commissioning for analog systems engineering personnel, it is relatively unfamiliar, or a little more difficult. As we all know, the IP Camera is relying on the existence of the network, the network itself and the status of the application effect is closely related to network cameras. Throughout the network environment based on the application of effects, such as network monitoring system is based on a network has been built, the original network infrastructure can meet monitoring requirements, needs to be considered; while the new network-based network monitoring system, Construction of the new network will be faced with greater investment environment, users may make large investments unbearable. In addition, access to the network camera will be domain names, IP addresses and other problems, and network security issues are also the focus of the user, so that the joint effect of many problems have hampered the widespread application of network cameras. But in network security, now Megapixel IP cameras have built-in VPN protocols of international norms, enabling seamless connectivity and network security devices can be safely connected to the internal LAN from the Internet, which greatly improves the audio and video security, to prevent the camera through the network cable intrusion internal network. In addition, the generally HD Network Camera also has a built-in UPNP protocol, plug and play, no need to change the firewall settings and other network security devices, but also reduces debugging difficult.
Second, some standard definition network camera image effects not as analog cameras and network camera also vexing non-real-time, are also boosting the still massive selection of analog cameras and surveillance market firmly occupy the mainstream position. However, with improvements in technology and user needs improvement, high definition has become security vendors continue to pursue the goal, 720P/1080P HD camcorder increasingly favored by the users. In some mainstream manufacturers, for example, last year the grand launch of a full range of one million high-definition cameras are to follow the standard H.264 algorithm, can achieve 1920 × 1080,1600 × 1200,1280 × 720 million full-time HD video support 1600 × 1200 multi-stream video output, can easily achieve high-definition monitor, can truly capture clear image detail, picture quality than conventional D1 promoted four times, so that the high-definition camera applications has become more widespread, you can optimistic forecast, in high definition , network video monitoring trends, the network will show the HD cameras and rapid development momentum.
Finally, the IP Camera costs are still high. Compared with analog cameras, because the network camera market is not mature, its price is high, so a lot of industry users prohibitive. With China's domestic enterprises bigger security camera gradually mastered the core technology, domestic compression chip large-scale applications, many domestic security companies have introduced a wide variety of network cameras. Some manufacturers even have a full line of HD IP Camera , to provide users with more choice. This means that prices will inevitably have a more substantial downward adjustment, the current price ofHD IP Camera has become increasingly close to traditional analog cameras, so that more users can affordIP Camera.

Network monitoring will become the mainstream of remote monitoring security
Core Tip: With the improvement of living standards as well as security requirements increase, traditional analog surveillance has been far from localized to meet market demand. The rapid development of network systems, making rely on the network for remote monitoring possible.
With the improvement of living standards as well as security requirements increase, traditional analog surveillance has been far from localized to meet market demand. The rapid development of network systems, making rely on the network for remote monitoring possible.
For large-scale monitoring systems, network monitoring relative local monitoring has unparalleled advantages, embodied in monitoring approach is more flexible system construction and maintenance cost is relatively low, a greater amount of data can be stored, data storage means more data application form wider, higher degree of system integration. On the other hand, network-based video surveillance breakthrough time and geographical constraints, as long as the network exists where you can establish a network monitoring system, eliminating the need for traditional cabling and line maintenance costs, reduce monitoring costs; User In the case of authorization, you can monitor the demand at any time without geographical restrictions, to achieve plug, that is, that look.
3G networks to promote the rapid development of wireless networks
Popularity of 3G networks, and promote the rapid development of wireless networks. Moment, 3G wireless networks has become inconvenient for city distribution network construction project in preference. With wireless city blueprint put forward, 3G wireless technology has been widely used for wireless city construction played a major role in promoting. Safe City project in the experience accumulated over the years, IP surveillance equipment have been widely used in urban construction projects for high-definition, high efficiency, network security monitoring has provided a guarantee. Basic network construction is to achieve the conditions necessary for network monitoring, and 3G wireless network is in safe city construction plays an important role, since the Safe City project involves many aspects of monitoring system construction, the city network roll-out and not cover all areas, which requires no network coverage area network cabling, but difficult to implement this project, the cost is high, it will directly affect the application of IP Network Camera and data transmission. 3G wireless network with high-speed transmission, easy deployment, mobility and other prominent advantages, can effectively resolve network problems such as wiring works hard, is conducive to safe city construction wireless, networking. 3G technology is currently more police enforcement vehicles used for police surveillance, urban patrol monitoring, armored monitoring, flood control command and other items.
Policies to promote peace blessing rapid development of urban construction
Policies to promote the peace blessing the city's development, especially 3111 safe city, digital city, smart city concept put forward, so that peace has been rapid development of urban construction. Twelfth Five-Year Plan also clearly states: strengthening public security system, to adapt to the changing situation of the new public safety features, promote the establishment of prevention and emergency response initiative combining traditional methods with modern means of combining public security system. Clearly, government policies conducive to safe city construction plus hold fast smoothly, provide a favorable environment for the smooth development of protection, clearing the obstacles on the path of development strength.
Currently safe city construction, there are still some deficiencies, such as insufficient funds in some cities, you can not independently massive safe city construction. This is in addition to the relevant sector policy support, but also need to ensure adequate funding. Of course, the city should be based on their actual conditions, consistent with the size of the project to build. For the peace of the city has begun to take shape the project, in order to save the cost of inputs, in the original project, based on the use of analog cameras + DVR, or partly upgrading the system first, and gradually formed a network video surveillance, high definition.
Network surveillance cameras in the safe city construction difficulties ahead
Currently the IP Camera safe city construction in the proportion of about 10% of applications, network camera do not form large-scale applications, mainly in the following three reasons: First, complex networking system, debugging difficult. IP Camera are known to exist relies on the network, the network itself, the development of the situation and the effect is closely related to the application of network cameras. Throughout the entire network environment, the network infrastructure is not sound, coupled with systems engineering to build a larger network, access network camera will be domain names, IP addresses and other problems, and network security issues are also the focus of the user, So many questions, which restricts the development process of the IP Camera. In this regard, Viagra, as dot-com has excellent performance, VStarcam full range of Megapixel IP camera built-in VPN protocols of international norms, enabling seamless connectivity and network security devices can safely access the internal LAN from the Internet, greatly improved audio and video security to prevent the camera via the network cable intrusion internal network. In addition, VStarcam HD IP Camera built UPNP protocol, plug and play, no need to change the firewall settings and other network security devices, greatly reduces the difficulty of debugging.
Secondly, the high cost of network cameras. Compared with analog cameras, network cameras, higher prices, so a lot of small and medium-sized users away. With China's domestic enterprises bigger security camera gradually mastered the core technology, domestic compression chip large-scale applications, many domestic security companies have introduced a wide variety of network cameras. Granville dot-com has a full line of HD IP Camera , including gun camera, dome cameras, infrared cameras and high speed dome cameras. Meanwhile, also launched a series IP surveillance products, including IP cameras, codecs, NVR and other equipment, to achieve a system solution IP-based, to provide users with more choice. This means that prices will inevitably have a more substantial downward adjustment, the current price of HD IP Camera has become increasingly close to traditional analog cameras, so that more users can afford network camera.

Analysis of the development trend of network cameras is simple and convenient type
Analysis of the development trend of network cameras is simple and convenient type
First, in the field of security, in the current market share, the traditional analog surveillance products still dominate most of the security business unit owned or application is still analog surveillance product knowledge, habits and their own background knowledge as well as digital, Lack of knowledge makes networking in product selection, involuntary still be inclined to analog surveillance products. As the "Security Manager" magazine No. 23 "concerned about network monitoring front-end" as discussed in the article: "On one hand, many of the works in network technology knowledge base is very low," this case, "the best way is to contractors conflict, because I know no one, so I do not play with this new thing or is my pick projects done by the manufacturers technical support "!
Secondly, in the field of civilian consumer, increasing the number of Internet users in China, but our broadband network usage environment is unsatisfactory, broadband communications monopolies reluctant to put their valuable IP address resource open to those who need to use, or to receive a huge monopolistic resource use fees, as a network video products required two necessary conditions: IP address and bandwidth was artificially tightly grabbed, call you want to use can not, can not bear to want to strike. Moreover, Internet users from all walks of society, people have various levels of knowledge, because knowledge of the network environment and the network uses both a lack of depth, coupled with the need to use a certain network camera network parameter settings, making the network camera in the civilian market promotion seemed a bit powerless. In this case, the product lineup as a digital IP Camera, one must realize the simplicity of use, it may be truly favored by the users in order to meet the low-end security engineering and consumer civilian individual users requirements.
But that does not mean using a simple form of technical content is simple, after several years of stumbling, IP Camera manufacturers have come up with another of the suspected fool some of the network camera, some simplifying network environment settings, such as VStarcam network camera is an outstanding representative.
1, built-in domain Bundled ------ use camera card's MAC number or other identification number corresponds to a physical device two subdomains, customers buy products according to the manufacturer after the preset domain name in the IE browser Browse images, benefits of doing so is to save the customer to DDNS (Dynamic Domain Name Service Provider) for two sub-domains cumbersome procedures, to some extent simplifies the customer's application settings, deficiencies still need to face a dynamic IP surreptitiously added to the router doing NAT settings.
2, UPNP port mapping automatically ------ customers do not need to buy multiple network camera will not operate to worry about, UPNP port mapping automatically through a router, allowing the device easily on the public network. To really plug and play IP camera.
VStarcam as the dot-com as a professional R & D and manufacturer of network camera, using UNPN plug and play technology, built-in commercial-level domain, with a complete front-end network video surveillance product line to meet the monitoring of clients in various industries products equipment needs and also provides a powerful back-end integration management software and implementation experience.

But that does not mean using a simple form of technical content is simple, after several years of stumbling, IP Camera manufacturers have come up with another of the suspected fool some of the network camera, some simplifying network environment settings, such as VStarcam network camera is an outstanding representative.
1, built-in domain Bundled ------ use camera card's MAC number or other identification number corresponds to a physical device two subdomains, customers buy products according to the manufacturer after the preset domain name in the IE browser Browse images, benefits of doing so is to save the customer to DDNS (Dynamic Domain Name Service Provider) for two sub-domains cumbersome procedures, to some extent simplifies the customer's application settings, deficiencies still need to face a dynamic IP surreptitiously added to the router doing NAT settings.
2, UPNP port mapping automatically ------ customers do not need to buy multiple network camera will not operate to worry about, UPNP port mapping automatically through a router, allowing the device easily on the public network. To really plug and play IP camera.
VStarcam as the dot-com as a professional R & D and manufacturer of network camera, using UNPN plug and play technology, built-in commercial-level domain, with a complete front-end network video surveillance product line to meet the monitoring of clients in various industries products equipment needs and also provides a powerful back-end integration management software and implementation experience.

HD network camera deficiencies technical problems to be solved
HD network camera deficiencies technical problems to be solved
Thanks to HD SDI HD display is a cloud flow, the display is uncompressed. For example, for the monitoring of medical procedures, surgery inside, the outside. A VCR has a single frame fill function, a video over we can take pictures, photographs survive in several fields of application are very practical. Or applications for banks, because the banks based on video-based services have not only security, more services to its business. Such as banks offsite trial orders, savings bank branch for approval of this document to report, you can borrow a cloud picture to upload. Another example is the public security evidence, etc., are also based on such a concept completed.
2012, a series of plug and play high-definition network camera technology products has been significantly glitch, so called domestic video surveillance "HD first year." 2011 With the continued development of high technology, high-definition monitor has no doubt become the security market, "hero." 2012 With HD products in a practical application in industries, high-definition technology is constantly penetrated into all industry specific applications to go. However, high-definition technology is a process of development, technology development is a problem-solving process.
A high-definition still insufficient
By monitoring the industry in recent years, the continuous development of the industry and the use of monitoring the number is increasing. But the process has sometimes met with such a situation: After the incident, police rushed to the scene and access to video, the incident was discovered, monitor screen characters blurred image has a lot of snow noise.
From the user perspective, the traditional standard definition content recorded surveillance system, it is difficult to provide or to meet user demand for monitoring the details, making the level and effectiveness of monitoring application is restricted. So I hope there is a new technology to break this limitation. From the technical point of view, SD product technology has no more space for development. From a market perspective, the market needs to have a new product to stimulate growth in the industry and markets. HD IP Camera just to meet the needs of multi-party, into the present and the future direction of development. Monitoring in the bustling city, you can see the facial features of pedestrians; monitoring counter in the bank, you can see the point of note details.
Second, what issues need to be addressed
With the development of computer network technology and the constant improvement of infrastructure, the network has begun to bring the convenience of changing our lives. The rapid development of network infrastructure for high-definition network camera has laid a solid foundation. HD surveillance systems need to be flexible to meet the deployment manager system and allocation of responsibilities; need to meet the users to the fastest and most convenient way to use video surveillance; need to meet the system's continuous expansion and construction. Megapixel network camera with the computer network system integration, to fully meet the demand for these applications. Since IP network access feature, administrators can deploy a flexible storage location for video surveillance and clearly related management responsibilities. Through the IP network interconnection feature allows users via PC, mobile phones and other computer network terminal requests monitor or video. As the topological characteristics of IP networks, the system can meet the constantly expanding needs. Therefore, high-definition network camera will be HD camcorder's main product types.
1, the monitor screen resolution problem
HD network camera must first solve the problem is to monitor the picture clarity. HD network cameras generally use one million pixels or more sensors for image acquisition, the current mainstream 720P HD network camera, for example, in the same scenario, the monitor screen to enhance clarity than CIF resolution at least eight times more, compared with D1 resolution enhancing at least two times.
2, interference problems
HD network camera solution is followed by immunity problems due to all-digital high-definition network camera systems for the collection and transmission, and its strong anti-interference performance. Reaction to the surveillance images that do not appear similar to the snow noise, ghost images, etc., so that images are always kept clean and clear monitoring.
Third, the future development of the intelligent combination of HD and
The cost of high-definition network camera is still hinder its rapid market development of the main factors. According to the survey, in 2011 compared to 2010 network camera prices generally about 10%, of which high-definition surveillance cameras drop of about 25%. However, with the high-definition network camera shipments increased, CCD, CMOS, and other core components prices, overall prices will decline further.
HD network camera with more industrial applications will be combined in the future can be achieved business information industry Megapixel network cameras with seamless integration, thus creating a higher system performance. For example, high-definition network camera through image recognition, real-time information will be communicated to a number of business units in order to play the role of rapid alert.
HD IP Camera will be better integration of Internet technology, can provide users with a variety of different ways and more real-time image stream. HD network camera also through E-MAIL, MMS and other tools to send alarm information and images. But also through micro-Bo, QQ and other Internet communication tools, data exchange with the terminal, such as real-time video broadcast and so on.
HD network cameras can be loaded according to the needs of users for various applications, with the high-definition network camera is the operating system for embedded devices. A variety of different applications can be downloaded via the administrator to HD IP Camera, just like our smart phones as download the application. This allows the application of high-definition network camera more in line with user needs.
HD IP Camera with smart features a combination of high-definition network camera megapixels intelligent algorithm to provide a good environment. Intelligent algorithm can be based on the original image definition, do some recognizable applications. For example: perimeter guard, stolen goods, dangerous goods legacy, traffic statistics, flame detection, face recognition, license plate recognition, etc., to meet the needs of customers in different industries.
Epilogue
With the security industry, the growing demand for high-definition applications, high-definition IP Camera market is in a stage of rapid growth, despite the system cost, equipment, application performance and other factors of distress, but with the HD network camera technology continues development of high-definition network camera will become the next high-definition monitor marketplace. Its market demand is also experiencing unprecedented surveillance industry diversification. I believe that with technological advances and breakthroughs, HD network camera will appear more intelligent, easy to use as well as a wide range of product features.

HD triggered megapixels surveillance camera disputes
HD triggered megapixels surveillance camera disputes
Is popular with a surge of high-resolution boom megapixels digital camera lens became the most important accessories. In many cases, the end user wishes to obtain the image quality and higher resolution video quality. However, there are too many monitoring systems manufacturers and vendors still do not realize that, for megapixels IP Camera, the lens is not simply the lens. In China, some security vendors have opened the Pandora's box of megapixels lens.
Irreversible trend
From 2010 onwards, HD high-definition equipment has begun to be applied to the basic monitoring facilities, network upgrades and broadband broaden let megapixels see room for growth in the Safe City project. According to statistics, megapixels lens output accounted for 30% of the total output of the lens, reflect this phenomenon can, the next 3 to 5 years HD lens in the market will be dramatically increased.
Obviously, megapixels IP Camera demand continues to increase, the traditional optical imaging device can not give full play to the CCD HD; megapixels HD IP Camera lens with the traditional analog cameras, high-resolution cameras with high quality lens. Dealer or user, the future trend of megapixels is no doubt; many manufacturers, high-definition contrast normal lens is more conducive to monitoring.
There is no doubt, a standard analog camera lens megapixels lens imaging results are very different. In practical applications, such as license plate recognition, face recognition using a HD IP Camera, thereby obtaining a high resolution image and presents some of the necessary details.
Traffic, for example, the use of megapixels IP Camera can not only capture the license plate information, or even the appearance of the crash can be seen clearly. The event of a hit-and-run problem, high-definition images can help the police quickly locked the suspect. In addition, high-definition probe can cover more space, you can replace multiple traditional analog cameras. The initial construction cost savings, while also able to reduce ongoing maintenance costs.
In practical applications, high-definition lens digital zoom the image to enlarge, including the part of the image edge. Unlike monitoring fish-eye, fish eye is the use of ultra-wide-angle lens, View ultra-wide field has a better image resolution, the situation of a barrel distortion.
Technical challenges
Non-edge definition is premised on the image resolution continues to increase. Aspherical lens plays a very important role in the case of a measure of edge sharpness. Aspheric lens can be effectively added to the edge enough fiber largely avoid the blurring of the surface of the dome. However, some manufacturers use a small focal length lens, of the aspheric lens, the the marginal glass must be carefully polishing, the reason is because of the particular material, can not supply.
Even so, the grinding technology is still bottlenecks caused to real-world applications. Rarely been seen in the mass production of aspheric lens coated with a layer of expensive materials, of course, is a selling point, but also a necessary technical indicators.
Typically, different from the ordinary lens megapixels resolution and edge sharpness, aspheric lens in addition to the central clear edge to maintain a high-resolution imaging through a special optical design to achieve ultra-low dispersion lens.
In general, the lens manufacturers will focus on three areas: sharp, the lighting and the integrity of the image. These are also the Buyer test standards. Megapixels lens requires strict assembly and complex materials and equipment program.
Domestic test of the overall strength of the lens
Compared to a single product, than the natural lens manufacturer Tamron Japan's Fuji. It had to be sure, the Japanese lens in purity, to spend the accuracy and layer technically better than us. But compared to the overall strength of the lens in Japan, mainly domestic. The domestic purposes Walking customized service and cost-effective cost control, management easier.
HD digital high-definition prevalent in the security industry, to allow more users to understand the importance of image quality. When selecting a product, the overseas Mao judgment is a comprehensive cost-effective, even if the lens of Japan in China also has a price advantage, but the performance stability should not be ignored.
Surveillance camera lens can mix and match
Accordingly, by the intelligent edge device may achieve better image quality, high-definition video in low broadband transmission and can reduce the storage capacity.
Megapixels lens design still faces enormous challenges, higher than the ordinary lens assembly process and the accuracy of the machine. In any case, megapixels aspherical lens structure characteristics to achieve true HD plays a vital role. So far, it has achieved it comes to network monitoring Full HD front end to the back-end equipment. HD-SDI still stuck in the front-end solutions provider. Megapixels lens mature HD IP Camera solution, you need to completely solve the back-end issues, through the continuous upgrading of technology, this desire is just around the corner.

HD! Megapixel camera can do the same
HD! Megapixel camera can do the same
One reason is that megapixels network camera after years of development, can not get to the application still highbrow large-scale promotion Contractors true megapixels network camera concept fuzzy understanding is not deep enough, not blindly launched. Many suppliers megapixels network camera publicity to works to cause a lot of wrong understanding megapixels reach HD effect, "How can full real-time monitoring, the higher pixel image is more clear" these The problem article will sort out one by one.
"What is the megapixels network camera? Over 1 million pixel network cameras megapixels network camera is called.
"What is the HD camcorder? 720P, 1080P, 1080i camera is a high-definition camera.
"What is the 1080P network camera? 2-megapixel network camera 1080P network cameras.
"What is the good megapixels network camera? Pixels the higher the better.
"How to use megapixels network camera? Funds permitting, can be used.
It is understood that the megapixels network camera into the domestic security market has been nearly three years since the end of 2009, the mainstream monitor manufacturers in the security industry set off through the form of a new exhibition, will be met, the project will promote the "the HD wave" baptism, many of the works has the effect of megapixels IP Camera is not equal to a high-definition camera, HD cameras have high demands on bandwidth and storage, up to HD need not just the camera HD, but a set of monitoring solutions should be HD, "" megapixels point instead of the line "these basic concepts have a certain understanding of. However, A & S think, works directly face the user groups, a security product is good or bad works to the whereabouts of the user to do the rendering and display. Contractors megapixels HD IP Camera products ambiguity of the concept, it is bound to hinder the further development of the product, which restricts the promotion of products. Megapixels IP Camera market needed to be educated, product concepts need to further clarify the misunderstanding of Contractors need further corrected.
It is due to the rapid development of surveillance cameras pixels, enter megapixels, the original standard definition camera has been unable to meet existing products, resulting in a lot of people on the vague concept of megapixels network camera. Through the use of publicity and Contractors, Engineering and suppliers in the security industry generally believe that 1.3 to 2 million pixels, SVGA, SXGA, WXGA, UXGA, WUXGA, QXGA format presented is a form of megapixels Webcams.
A wide variety of megapixels HD IP Camera, the manufacturers used different rendering formats, so many monitor manufacturers to use U.S. SMPTE HDTV standard, resulting in the definition of HD. "Domestic security industry said HD resolution digital video camera 720P and 1080P both formats, and the corresponding sets of transmission, display, storage, management platform constitutes its aspect ratio is defined as 16:9 "Axis Technology Special Advisor Zhao West column explains.
HD! Megapixel camera can do the same
Megapixels network camera the experienced "megapixels stage" (initial 1.3 megapixel main screen showing mainly to SVGA, SXGA format) to "high-definition stage (HDTV presentation standards, requirements to render the screen as WVGA WXGA or 720P, 1080P, 1080i several formats) to the ultra-high-definition stage of the network (more than 300 million -500 million pixel camera), three stages, the product line has tended to complete. Megapixels IP Camera format is a lack of uniformity when HD gradually when it is considered to be the image format standardized requirements, different manufacturers use different resolution, compression technology, video codec, a frame rate, aspect ratio, etc., making the quality of megapixels HD IP Camera appear uneven.
Choice in the face of high-definition camcorder with megapixels camera, many of the works megapixels camera and HD camcorder opposition that close to 1280 × 720 and 1920 × 1024 this two resolution camera to the back-end HD 720P and 1080P image, this understanding is very narrow. In fact, nearly 1280 × 800-1280 × 960 and 1600 × 1000-1600 × 1024 (or SVGA, SXGA, WXGA, WUXGA, UXGA, QXGA) resolution camera together with the corresponding system, can render 720p (HD) and 1080p (FULL HD) effect. Therefore, we believe that the resolution within the above range, you can freely switch between 4:3 and 16:9 without losing picture megapixels network camera, can achieve true high-definition.

High-definition monitor will enter the low-cost era
High-definition monitor will enter the low-cost era
In recent years, as the security industry continues to develop, grow, HD network camera is now also discussed theory, exploration, become a reality. And real in our midst applications in all walks of life, especially in the field of safe city, safe campus, safe community, government, enterprises, institutions, and road monitoring, the use of high-definition monitor not only can see more details and a broader perspective, the cost of using the system are also being gradually reduced.
Early HD IP Camera just listed, mainly by sales of foreign manufacturers, the lack of abroad HD IPC manufacturers in supporting low-light, resulting in applications with limited sales, coupled with their high labor costs, the price is high. Development and the development of HD IP Camera some misunderstandings so many industries, especially in the price has been high, and stop looking, ordinary users are more difficult to accept, to some extent, a serious impediment to HD IP Camera popular. Such situation, the domestic security practitioners have been exploring with the development of high-quality low-cost innovative technology, they think in the mall a few hundred dollars on the field of consumer electronics digital camera can reach a few megapixels and security camera, whether domestic or thousand dollars imported analog cameras, hundreds of thousands of pixels, price and quality do not match. So, start a digital camera-related R & D, processing and optical technology of the photosensitive thorough. In 2008, a major technological breakthrough, the movement of the digital camera to the security cameras, to achieve a high quality and low cost.
With the continuous development of China's domestic security market, mature, and gradually mastered the core technology of the camera, the domestic audio and video codec chip large-scale applications, many of the domestic security companies introduced a wide variety of network cameras. Some manufacturers have a full range of HD IP Cameras, to provide users with more abundant. Shenzhen Joint feature together focus on the research and application of network video surveillance solutions, specializing in the production of research and development of HD IP Cameras, high-definition network matrix, HD NVR, integrated monitoring and management platform system and a series of products and the overall HD. Comply with industry, the market demand, the recent heavy launch: "popularity of HD Network Camera 2 million pixels, storm price of 499 yuan," the price is definitely the magic price in the industry, ultra-low-cost video surveillance network HD universal storm. The price of HD Network Camera closer and closer to the traditional analog cameras, so that more users can afford the HD IP Camera. So for now, the HD IP Camera into the more users in a short period of time. And the annual rate of more than 30% of the incremental development, especially in the past two years, HD IP Camera is to usher in the explosive growth and rapid spread, no exaggeration to say that the development of HD IP Camera is "everything is ready" only due to the "Dongfeng", this "Dongfeng" is that people should reverse the mistaken view of the past million high-definition, to re-establish a correct understanding of the millions HD.
