Network surveillance cameras do not sell products sell services
IP video surveillance market has been developing steadily since 2009 , until 2011 network monitoring set off a boom in the domestic security market , today , even billion market opportunity in front of us , IP HD monitors praised still face the embarrassing situation . Megapixels HD has become a buzzword in the security industry , lack of standards and the second and third tier markets hiatus become the biggest obstacle restricting its development .
Advantages and disadvantages of IP surveillance , but how to make the network video surveillance market is more mature, still seems to be a topic worth exploring .
HD network camera monitoring the fate of small innovative change
Analog monitoring technology as the representative of the video surveillance has improved the development history , IPnetwork camera surveillance is an emerging field , completely contrary to analog surveillance technology. There are many large contractors said , IP surveillance can indeed bring greater benefits for them , but if you want to expand the market, how to achieve low cost, high reliability it? Time will be able to solve the problem, but I am afraid there can solve the urgent needs to be seen.
User requirements determine market trends, end-user point of view of network video product features but will IT technology , software, etc. through the Internet integration. Even this little " innovation" is indeed capable of causing widespread concern of users , network IP Camera as the representative of the product with better flexibility and scalability , dramatically reducing installation costs. Despite the need for more complex network setup and monitoring software , but the long-range surveillance undoubtedly solve many problems.
Trends in wireless network monitoring platform
To meet the needs of users , network video surveillance to be large-scale promotion . Promoting safe city construction projects , the first-tier cities is almost complete analog to upgrade high-definition monitor , the user can truly appreciate the advantages of IP surveillance which it ?
Network camera is no longer simply the product features, it is a manifestation of services. Therefore, how to provide effective services will be an important factor in security companies to gain market share , product resolution and prices have not been listed as a key factor . To allow users to better understand the products, services should include not only maintain , but service. Respond quickly to changes in market demand, and constantly optimize the product , with standardized interfaces and protocols.

Network camera and analog cameras What is the difference ?
Network camera and analog cameras What is the difference ?
Analog cameras and IP camera are today's mainstream products are used in various industries , so we use them in what they know about what is the difference between the two is it ?
Network camera ( digital camera ) is simply directly to the camera itself and the internal circuit by the CCD image captured into the digital signal via a network cable , the switch directly transmitted to remote monitoring easily . Simple analog camera image is converted into an analog signal , is transmitted through a coaxial cable, generally used for closed-circuit monitor . The difference between analog cameras and Network camera as follows:
1 , clarity
Network Camera : Progressive scan (up to millions or even tens of millions of pixels ) , more suitable for capturing moving targets , even moving at high speed can also provide a clear picture of the image .
Analog cameras : interlaced ( resolution 4CIF, can only reach 400,000 pixels ) , catch them at high speed moving objects , can cause image blur.
2 , monitoring
Network Camera : Built-in WEB, using a standard WEB browser on your PC , you can manage and view images. The ability to remotely manage and view images. Presence on the network camera can be remote image data hard drive, easy to find , easy to store, will not be destroyed.
Analog cameras : closed , only watch inside , not remote monitoring . Video data can only be stored locally , not remotely view , easily destroyed criminals .

What are the advantages of video surveillance network camera ( 2 )
What are the advantages of video surveillance network camera ( 2 )
Five reasons : Integrated PTZ control and input / output ports
For analog cameras is concerned, if you need to realize PTZ ( pan and zoom ) control , in addition to video cabling , but also need to provide specialized control signal line , it will increase the cost and inconvenience to the construction . network camera can transmit video signals through the same network , and PTZ control commands , which can greatly reduce installation costs and to achieve higher user flexibility . In addition , network camera can also be integrated alarm input and output ports , to achieve joint control of other security systems alarms , door locks and the like. These features in addition to further cost savings for users , but also further increase the network camera features and integration with other systems potential.
Six reasons : Integrated Audio
In some applications, the audio information is becoming increasingly important. For analog systems , if you need to get audio support, only through additional audio wiring work can be achieved. The network camera can capture the audio through the built- in microphone at the front end or other external device, and the audio information synchronized with the video information , audio information, or be integrated directly into the video stream which , finally transmitted to the rear end of the network or to monitor recording device . In fact, the only network camera can make audio support functions become easy to install and cost-effective , it can support full-duplex audio , so that the user can use the phone as easy to use audio features . In the example in Figure 7, the network camera allows users and visitors for two-way audio communication, and remote control door opening and closing .
Seven reasons : safety communications
Analog cameras use coaxial cable to transmit video information , which does not have any encryption and authentication mechanisms. In this case , as long as they know the location of the video cable , anyone can watch one video screen by means of the transmission line ride . Worse, since the bad guys can be a deceitful , video surveillance will be a critical signal to switch to other sources , so that the user's video surveillance system complete failure ( as the movie scene often appear like ) . But in terms of the network video system , network camera can capture the video signal is first encrypted and then transmitted through the network , which can ensure that the video information can not be accessed or tampered with by unauthorized personnel . System through the use of high security digital certificate authentication for connection requests , to ensure that only specific network camera to be able to access the system , thus effectively avoiding fraud. network camera can also join the "Watermark " message in the video data , the " Watermark" summary information can include images , time, place, date, user information, alarm information, etc., so that after security incidents to ensure an effective system to save evidence. These functions in a simulated camera is simply impossible to achieve.
Eight reasons : flexible, economical and practical infrastructure based
The analog video signal is normally transmitted through expensive coaxial cable , fiber optic or wireless private , no matter what the transmission technology, the image quality will receive the impact transmission distance. In long distance transmission when the analog video signal , various intermediate devices must fit precisely and to ensure that the range of adjustment of the image quality degradation can be received in a situated . In addition, the power supply for the camera wiring , add alarm input and output , and audio cabling installation projects will further complicate deployment . The IP-based digital systems are able to overcome the relatively low cost of these difficulties , and to provide users with more options.
Like at any one location in the world via the Internet can view pictures on the website , you can at any corner of the world through the Internet network camera provide viewing digital pictures that span continents and oceans will never long-distance transmission quality degradation caused by the phenomenon . The difference is that with analog video , IP network technology is a global standard of mature technology, IP-based video stream can be compatible with each other through a variety of transport infrastructure on a global scale . As a result of the type of packet -based communications , many different types of data stream can be transmitted over the same data line. In some new projects which often uses low-cost Category 5 cable , gigabit Ethernet , and a data cable can transmit hundreds of full frame rate video streams .
Nine grounds : the real digital solutions
In an analog video camera , an analog signal generated by the first CCD sensor are converted A / D ( analog / digital ) converter to digital signals, so that the video image and sound can be processed through its built-in DSP chip. After the digital image signal is then processed by the DSP and converted back to an analog signal for transmission on coaxial cable. Finally, when the analog signal reaches the rear end of the
DVR , the DVR has been re- digitized and stored on the hard disk. As can be seen , in this process , transforming the image signal to be subjected to three , and each time the conversion will cause different degrees of decline of image quality . In the network camera , the image After digitization digitization will remain a state without the need for multi- frequency / analog or analog / digital conversion , thus avoiding the image degradation phenomenon.
Ten reasons : lower total cost of ownership
When it comes to these network camera have a range of advanced features , some would say that these advanced features will inevitably result in increased equipment costs. Indeed , if only to get the price of the camera itself to do a comparison, network camera certainly seems to be rather expensive. However, if the object is to compare the cost of each video signal , then the flexibility of high -performance network camera
Obviously you can and DVR -based analog systems equal. As the network video system applications and back-end storage capabilities that the industry can use generic, open standards-based server hardware , rather than as an analog system that must use a dedicated hardware platform ( such as DVR), so in many system configurations, based on the front-end equipment cost network camera video surveillance system is very
To appear lower . This is for a number of large systems is especially important because the storage and server hardware typically account for a large part of the total cost , while the use of IP camera can greatly reduce the cost of device management and acquisition area. Cost savings come from the infrastructure network camera are used . In addition to carrying video surveillance business outside , Internet, LAN and wireless
Various networks , such as IP-based network can also carry other types of applications within the enterprise , compared with the traditional coaxial cable and optical fiber, the construction cost of these networks is very low .
Conclusion: The future belongs to the network camera
JPFreeman leading industry analyst predicted that in the field of video surveillance , network camera market will be the fastest growing market , sales network camera will surpass analog camera in 2008 . Because IP -based network security management (SecurityManagement) greatly expanded the understanding of people for security management and implementation tools, and therefore is considered to be the development direction of the next generation of advanced security management. On the other hand , some analog cameras due to the defects in flexibility and performance , and therefore can not meet the requirements of next-generation security management , network camerais bound to be replaced . As the network camera will capture images as well as the ability to frame intelligent image processing stripped from similar back-end equipment such as DVR , so the size of the video surveillance system can no longer restrict the ability of the back-end computing equipment , systems obtain greatly improved extensibility . End- user network video surveillance system can choose to use cost-effective general-purpose servers and storage for video , but you can also choose the product most suited to their needs from a large number of video management and analysis software.
In summary, the network camera enables users to their applications can be transferred from the special equipment (DVR) to open systems which , in addition also allows users to take full advantage of the network, the advantages of digital and intelligent , all this will constitute a powerful promotion of force, so that more and more users choose thenetwork camera.

The difference is that with analog video , IP network technology is a global standard of mature technology, IP-based video stream can be compatible with each other through a variety of transport infrastructure on a global scale . As a result of the type of packet -based communications , many different types of data stream can be transmitted over the same data line. In some new projects which often uses low-cost Category 5 cable , gigabit Ethernet , and a data cable can transmit hundreds of full frame rate video streams .
Nine grounds : the real digital solutions
In an analog video camera , an analog signal generated by the first CCD sensor are converted A / D ( analog / digital ) converter to digital signals, so that the video image and sound can be processed through its built-in DSP chip. After the digital image signal is then processed by the DSP and converted back to an analog signal for transmission on coaxial cable. Finally, when the analog signal reaches the rear end of the
DVR , the DVR has been re- digitized and stored on the hard disk. As can be seen , in this process , transforming the image signal to be subjected to three , and each time the conversion will cause different degrees of decline of image quality . In the network camera , the image After digitization digitization will remain a state without the need for multi- frequency / analog or analog / digital conversion , thus avoiding the image degradation phenomenon.
Ten reasons : lower total cost of ownership
When it comes to these network camera have a range of advanced features , some would say that these advanced features will inevitably result in increased equipment costs. Indeed , if only to get the price of the camera itself to do a comparison, network camera certainly seems to be rather expensive. However, if the object is to compare the cost of each video signal , then the flexibility of high -performance network camera
Obviously you can and DVR -based analog systems equal. As the network video system applications and back-end storage capabilities that the industry can use generic, open standards-based server hardware , rather than as an analog system that must use a dedicated hardware platform ( such as DVR), so in many system configurations, based on the front-end equipment cost network camera video surveillance system is very
To appear lower . This is for a number of large systems is especially important because the storage and server hardware typically account for a large part of the total cost , while the use of IP camera can greatly reduce the cost of device management and acquisition area. Cost savings come from the infrastructure network camera are used . In addition to carrying video surveillance business outside , Internet, LAN and wireless
Various networks , such as IP-based network can also carry other types of applications within the enterprise , compared with the traditional coaxial cable and optical fiber, the construction cost of these networks is very low .
Conclusion: The future belongs to the network camera
JPFreeman leading industry analyst predicted that in the field of video surveillance , network camera market will be the fastest growing market , sales network camera will surpass analog camera in 2008 . Because IP -based network security management (SecurityManagement) greatly expanded the understanding of people for security management and implementation tools, and therefore is considered to be the development direction of the next generation of advanced security management. On the other hand , some analog cameras due to the defects in flexibility and performance , and therefore can not meet the requirements of next-generation security management , network camerais bound to be replaced . As the network camera will capture images as well as the ability to frame intelligent image processing stripped from similar back-end equipment such as DVR , so the size of the video surveillance system can no longer restrict the ability of the back-end computing equipment , systems obtain greatly improved extensibility . End- user network video surveillance system can choose to use cost-effective general-purpose servers and storage for video , but you can also choose the product most suited to their needs from a large number of video management and analysis software.
In summary, the network camera enables users to their applications can be transferred from the special equipment (DVR) to open systems which , in addition also allows users to take full advantage of the network, the advantages of digital and intelligent , all this will constitute a powerful promotion of force, so that more and more users choose thenetwork camera.

What are the advantages of video surveillance network camera (1 )
What are the advantages of video surveillance network camera (1 )
Generally speaking, to a lot of factors involved in the security industry to converged IP networks process , to be discussed below is not limited to network camera and analog cameras are different in all aspects . Such as system performance , openness , interoperability , flexibility, sustainability and network connectivity, and other factors are to be considered important content. However, this article will discuss mainly for the 10 most important difference between the current IP camera and analog cameras existed , and further analyze why these differences is a key factor when purchasing the next camera must be considered .
One reason: the end of interlaced scanning problems
Analog cameras at high resolution (4CIF) condition will encounter a very prominent issue that interlace problems. This is because some of the analog video image is composed of scanning signal lines , each of a complete image field signal is again composed of two interlaced , even if the DVR is connected to the analog signal is true . This means that we see each image acquisition time is composed of two different " demi " picture merger .
Figure 3 is the actual effect of the progressive scanning and interlaced contrast to auto screen 20km / h speed of travel . As can be seen from the figure , either progressive or interlaced , the still picture object ( such as a brick wall ) can be clearly presented. However, for a moving object ( such as cars and driver ) , the interlaced picture significantly blurred. As can be seen from the enlarged picture detail , from the use of progressive scan picture you can clearly identify the driver's facial contours , while interlaced scanning is impossible to see. If the driver of a car theft thief , then obviously interlaced picture useless to hunt for a job .
Two reasons: to support PoE technology to effectively reduce costs and improve system reliability
PoE (PoweroverEthernet), means to provide power to the device through the Ethernet network technology , the standards required by the IEEE802.3 af , IT is a mature industry standard . PoE technology allows network devices can receive data and power simultaneously work over a single Ethernet Category 5 cable , facts prove that the technology can save a lot of installation costs for the user. This means that users do not have to support PoE cameras specifically for power installation work , while analog video surveillance systems for analog camera power has always been a major engineering difficulties , but also one of the major costs. In addition , support for PoE enabled network camera also can be used in conjunction with UPS uninterruptible power supply system , to achieve centralized management of power , thus greatly improving the reliability of the system , the network camera can still work in case of power failure . As can be seen from Figure 4 , regardless of whether support PoE , PoE network camera can benefit from the technology .
Three reasons: one million pixel resolution
Due to constraints NTSC / PAL standard , the highest resolution analog camera has been limited to 4CIF, roughly equivalent to 40 million pixels look. In recent years , high-resolution computer monitors and digital IP Camera continue to emerge , end users have begun to require millions of pixels of image resolution up to the level of end-user video surveillance applications also began to make a similar request . Webcams
Like the highest resolution machines can reach millions of pixels or higher , and therefore can provide more picture detail and cover a larger area ( Figure 5 ) . High resolution to ensure safety in the accident, you can clearly distinguish facial features perpetrators or their handling of goods from the video screen or monitor the video, so that users will not be wasted for the security system investments. In addition , high-resolution camera feature allows the network can also provide some, such as digital PTZ (Pan / Tilt / Zoom) and other special features .
Four reasons : the intelligent integration to the front
In the current video surveillance system, there are too many video data is recorded and stored, but these data are mostly unimportant pictures , information important events tend to be submerged in a flood of video data which , giving the event analysis and processing of a great deal of difficulty , but also a waste of valuable storage resources. Latest appear intelligent video technology to solve this common problem may be provided, and has become the next big trend in online video development. High-end IP Camera can fully meet the needs of intelligent video applications , they can be built into mobile video detection (VMD) and event management functions , so the camera itself can decide when to send video , at what frame rate and resolution to send, and when should alert the security personnel which prompts them to pay attention to the monitor screen or take appropriate action. Even some advanced intelligent video analysis algorithms ( such as license plate number recognition , people counting , etc. ) can also be integrated into the network camera were .
By using network camera, intelligent systems can be integrated into the front end of which the video surveillance equipment , enabling users to get a more efficient and powerful than traditional DVR or other centralized system of video surveillance solutions . Intelligent network camera also solved another dilemma in the field of video surveillance is emerging : the limitations on the computing power of a centralized video surveillance system can not be achieved on a large number of real-time video analysis . The network camera has a dedicated , highly integrated hardware, its own advanced video analysis algorithms can be realized , this feature greatly reduces the performance requirements for the back-end device , so that users can build a massive surplus of intelligent video systems .

Development of low-end network camera
Development of low-end network camera
With the upgrading of the network camera technology and improve the quality of product performance , network cameras subsequent promotion and application will be more extensive.
Currently, the most important market of network video surveillance is still concentrated in the city of peace , finance, transportation , education, electricity , energy, operators, prisons and several other major industries. However, the consumer market is the largest civilian cake , only into the household, can truly be said to have spread. In the process of network monitoring products to the market penetration of applications in the low-end to high-end products with the existence of space and the development of its own advantages .
Low-end camera division
All along, everyone 's impression of network surveillance cameras are expensive, it is an indisputable fact. However, according to market research , the current low price of network video surveillance cameras are usually less than $ 1000, and some loose money and not even a similar standard analog surveillance cameras .
The reason , in fact, more because of the simple combination of CMOS camera surveillance cameras and low-end single-channel network video server , network video servers and professional compared as multifunctional mobile phones with camera and professional digital IP Camera function results differences same.

How network camera pickup
How network camera pickup
Webcams pickup is actually a very easy problem to solve , and IP Camera picked up audio signals encoded in the front has become a digital audio signal , and then through the transmission lines to be stored on the NVR or computer , as opposed to the previous simulation pickup , pickup audio quality network camera can be greatly improved.
To solve the network camera pickup as long as the following conditions can be several :
1 encoding board used network camera designed with an audio input interface, network cameras used if there is no audio input interface , it is far from the pickup , and generally able to achieve the project level network camera that will have audio coding function , it has a corresponding audio input interface .
2 , the client software or NVR uses functional audio encoding and decoding of audio playback
Just with these two conditions, we can easily achieve network camera picked up audio and video synchronization .
So how to pick up the high-quality sound of it , this is a great choice on how to pay attention to the pickup device , first we have to determine what audio input interface of our IP Camera is also MIC LINE input , if LINE input , then we want to use active pickups with audio amplification , so pick up the effect will be good ; If the MIC input, the use of general passive pickups can also pickup 's . Of course , whether active or passive pickups pickups are all very different from the grade and price , from the ordinary to a thousand dollars per dozen pickups are some exceptions, for different grades of pickups in has a significant difference in the degree of noise reduction processing and the human voice .
Finally , there is a problem is often done by some simulated contractors asked : Network camera pickup cloth need not require an audio cable to the VCR , the answer to this question is : no ! Because the camera inside our audio has been encoded into a digital signal with our digital video signal transmission through the network cable together to come up our VCR .

Experience and technology : As the 3G era , each network camera manufacturers have got enough experience and technology, the era of 4G networks will be able to respond more fully to play its advantages too , to build a wireless smooth viewing , HD monitoring solution. 3G mobile monitoring equipment has been achieved , but the high 3G traffic charges already made a lot of network camera user can not afford to hurt . China Mobile said everything , 4G core network enables cost reduction of 70% , compared to the three operators will not be at the cost of higher 3G 4G tariffs . So the cost of 4G mobile phone monitoring will be reduced.
HD Development: In the first half of 2013 HD IP Camera concept has been speculation businesses are in full swing . HD has been monitored for businesses and users want . However, due to network speed , high-definition popularity has also become a problem. 1080P full real-time video you need to 4Mbps or more. Now 100Mbps download speeds 4G networks to meet the high-definition transmission. Monitoring the arrival of 4G era hides a huge opportunity but also to the many security companies have raised new technical requirements . Is bound to usher in a "4G hot" in the development of network camera after , how good control of this "4G hot" but for all manufacturers fierce battle strategy. There are many security companies are now ready to start 4G innovation . In the future development of the network camera , we hope to force more security products can enter into every line of every business , even the popularity of the civilian sector .

December 2013 , under a license issued 4G , wireless video surveillance system, or usher in a huge opportunity. All along, the network has been an important factor limiting broadband wireless video surveillance system development. The current 3G bandwidth is limited, high tariffs, limited transmission distance, poor mobility , resulting in a 3G network transmission network environment is difficult to see high-definition picture quality. Can 4G network or breakthrough to solve these problems ?
4G broadband network camera can solve the problem ?
Difficult to promote 3G wireless monitoring
In the 3G era , due to the limitations of the network, wireless video surveillance can only support up to QVGA resolution. Frame rate of around 5-10 frame , stream reaches up to 100Kbps, both in the application of mobile terminals , buses, mobile monitoring , etc., are just on the basis of the existing fixed-line monitoring of the use of wireless monitoring . 3G network coverage is small , currently only involved in some developed cities, due to the balance of different network base station , also caused a 3G network in the transmission signal strength is likely to cause uneven , resulting in the phenomenon of dropped frames , picture cards , resulting in a certain area within the network instability . As wireless monitoring needs more traffic support , funds generated will be not a small number .
Wireless video surveillance system for networking, combined with traditional video surveillance, the formation of a new application mode via 3G, 4G and WIFI wireless communications technology. Users can use a mobile phone or computer as a monitoring terminal device , anytime, anywhere to receive alarm messages and view the surveillance video.
4G or HD video transmission solve network
December 4 , the Ministry for the three operators issued the operating license 4G , 4G began full commercial , which gives wireless video surveillance development to create a good opportunity. What is 4G technology ? From the perspective of technical standards , according to the International Telecommunication Union (ITU) is defined , static transfer rate up to 1Gbps, high-speed mobile state can reach 100Mbps, can be used as one of the technologies of 4G.
Currently, the major international 4G standards are mainly two: the first one is dominated by the United States Intel WiMAX ( Worldwide Interoperability for Microwave Access ) standard , is the farthest distance 4G technology , is currently the fastest growing technology , in a mobile communication environment allows the maximum rate of the downlink and the uplink up to 75Mbps and 75Mbps. Generation of IEEE802.16m (WiMAX2) allows action to receive the downlink and uplink can reach a maximum speed 300Mbps, still pointing at the receiver up to 1Gbps. The second is LTEAdvanced standards, LTE enhanced , fully backward compatible with LTE, LTE is usually through the software upgrade , the upgrade process is similar upgrade from WCDMA to HSPA. Peak rate : Downstream 1Gbps, upstream 500Mbps.
4G network uplink rate of 20Mbps, downlink rate can reach 100Mbps, can effectively support the practical application of high-definition network camera , high-definition wireless video surveillance industry driven strode forward. Real-time video to 720P for example , using the standard H.264MainProfile compression algorithm requires at least 2Mbps HD IP Camera to get "high definition" visual effects , and full 1080P real time video you need 4Mbsp above , 3G seem " powerless ."
From the analysis of the spectral distribution of the information MIIT announced that China Mobile is fully deployed TD-LTE network , while China Unicom and China Telecom are FDD + TD hybrid network , the latter two can reach 1.5 times the speed of the former, covering the same cell when sufficient bandwidth can be provided to a user or device region . Therefore, the current license can be solved 4G network transmission problems.
And some companies on the 4G network transmission can solve the problem , but also to hold reservations. China Security Network Expert Committee , said Cong Lin , 4G licenses issued can not really solve the problem of network transmission . Mr. Lin Cong were analyzed from three reasons , first, the transmission bandwidth. Currently propaganda that is upstream rate of 20Mbps, downlink rate can reach 100Mbps, but actually in use, the use of large groups of customers , and will be facing the same problem 3G era , and ultimately to the speed of the terminal will be unable to meet the IP camera to use. Secondly, the stability and security issues.
Using 4G transmission mode , you need to consider his transfer stability and security, after all, we want to apply in the security monitoring , the requirement is stability and security , the use of 4G transmission scheme , so that we feel is unstable and is easily destroyed criminals . Third , cost. The current license was distributed to several major carriers , so they have to charge an additional fee to the present situation, certainly is flow as a unit, with the network camerahas become increasingly clear , the flow will also be a growing need , consequent costs will also be increasing.
4G network transmission technology can provide a good environment for the development could provide wireless HD video surveillance , but because of the tariff issue, base stations and other issues , 4G development of wireless video surveillance is still restricted. 4G broadband network in a short time is difficult to solve the problem , most of the development of 4G network camera is still in wait and see .

Network camera constantly develop derivative product type
At this stage, megapixels network camera to bolt and hemisphere -based, but as the technology matures and user needs increasingly clear , network camera will also be derived million HD network dome camera . As in remote or network monitoring system is not easy to build a network environment , in order to achieve the effect of high-definition , high-definition wireless network camera through to solve the problem of terminal access .
The improved algorithm into a trend
Core technology network camera is its video encoding compression technology. The current network cameras include general-purpose DSP chip technology and ASIC chip technology are two implementations . Due to domestic users for bandwidth and frame rate requirements more sensitive , requiring low bandwidth transmission rate of 25 still meet , so the algorithm for MPEG-4 H.264 algorithm , especially great in the domestic market . H.264 compression algorithm is 2-3 times more than the MPEG-2 , MPEG-4 is a 1.5 to 2 times . Therefore, the optimization of the H.264 algorithm manufacturers have much room for improvement to meet customer demand for bandwidth is occupied . In addition, the megapixels camera application H.264 encoding is the future direction of development, but now the situation is different each algorithm, compression quality, and the effect is different, more important is the resolution of the camera now supports 1920 × 1080P has come out, but at the same time almost no support 25ips manufacturers are now able to do 720P @ 25ips has been pretty good , so this is the future trend of development.
Infrared light to improve performance relative to ordinary HD IP camera sensor chip , the same size as a multiple of pixels increases , the resulting reduction in the size of the corresponding multiples sensitive point , so under the same exposure conditions , relative to the normal pixel HD camera network camera low light performance will be a lot worse. This means that if the night is much higher intensity of infrared fill light needs than ordinary pixel HD camera infrared camera . For example, a 1.3 million pixel 1 /3 " HD size CCD, with respect to the 430,000 pixels ( 480 lines ) 1 /3" size of an ordinary CCD, pixel high-definition CCD unit area is three times the normal CCD , the HD CCD pixel CCD photographic performance compared to ordinary sensitivity 1 / 3 , which is the HD camera the night of the root causes of poor results . Current practice is to extend the exposure time to compensate for poor low light performance deficiencies , but this will cause the image prone to smear phenomenon . If the high-definition image quality is much better at night , it can only increase the ambient illumination to supplement this regard.
For HD fill light , the HD camera infrared light to monitor different distances have different options to configure . Wide angle close- choice LED light board to fill light , wide-angle monitoring can be achieved at a lower cost , long-range due to the need for fill light intensity is relatively large , the angle is small, the use of ordinary LED difficult to achieve the desired effect. Therefore, in the distance with a strong directional selection , energy focused laser infrared light to fill light.
Usability improvements
Different from the traditional analog cameras ,megapixels ip camera comes to IT category , therefore , network cameraand analog cameras in use there is a large difference , especially for the operator and the use of personnel have higher requirements . For most domestic contractors, integrators and users, their traditional CCTV system is very familiar with the early stages of network cameras still in use , so the network camera in the development and design , taking into account the characteristics of these people , in the convenience and ease of use have installed on fully reflected , for example, supports PoE power supply, local video output , as well as convenient local debugging , support wireless functions.
Actively promote the high security
The basic definition of the term is accompanied by the start of high-definition television , became popular many years ago . However, for the surveillance industry , real large-scale application is a recent one or two years , which is mainly the rapid development of monitoring technologies, including coding technology, network technology , transmission technology , storage technology, high-definition monitor as possible, the overall technical program gradually mature, gradually being accepted by users ; of course , the user monitoring needs change , pushing for HD also played a positive role.
Shanghai Pudong District HD video coverage project is a typical representative. The project is currently the largest single cut definition video surveillance project , is currently the world's largest high-definition monitor projects. This project has more than one thousand monitoring points , large-scale adoption of HD technology , becoming the first Chinese surveillance market a veritable large HD monitoring project for the promotion of the development of high-definition played a positive role , a milestone .
Compared with the standard definition , whether it is from the resolution , display or fluency , the HD than SD advantage. From the resolution point of view , 720p resolution CIF resolution is 9 times , 1080i/1080p CIF resolution is 20 times the resolution of the display in the same environment , will be much clearer definition . From the display , the HD supports both large-screen display , and support for 16:9 widescreen display , you can greatly enhance the user's viewing experience. From the fluency of view, HD support higher frame rates , such as 1080i/1080p can support 720p and 60 frames / sec or 60 fields / sec , and its standard-definition images fluency than twice as high . Therefore , high-definition monitor is one of the most mainstream monitoring industry trends , as acquisition front-end , high-definitionnetwork camera trend is also moving along .

2014 Network Camera Development
Analog-to- network , high-definition monitor is a complete technical concepts
For monitoring system, HD is a complete technical concept , from image acquisition, conversion, compression, transmission, storage, control , and display a complete image processing . And on the whole video monitoring system, front-end image acquisition device that the camera head , is the core of the whole system, or the entire system can be likened to the "eyes ." If there is no front camera lens , video surveillance can not be achieved , just as human eyes can not see everything in the world is no different . If there is no front camera lens , the monitoring system will not be able to capture high-definition video surveillance images.
Over the years, the video surveillance industry researchers has been to improve the image resolution video surveillance and make unremitting efforts . With the continuous development of video technology, especially the image sensor chip technology, video surveillance cameras can not improve the clarity , the development of horizontal resolution to 420 lines from 380 lines , 480 lines , and then to 540 lines, 600 lines , 650 lines .
Before the advent of high-definition network camera , analog cameras resolution almost every year or two years, did not have a significantly improved , which has become the industry's attention. In 2006, the advent of high-definition network camera IPC , and soon set off "HD storm" in the industry . To meet the 2009 definition of market development , several industry vendors set up a joint HD-CCTV Alliance , the attempt to HD-SDI HD radio and television transmission mode to borrow central security monitoring system shortly thereafter , HD-SDI HD cameras come out. Currently , the industry's popular argument is that the IPC is called first-generation high-definition monitor , SDI is a second-generation high-definition monitor . The following web editor of China Security Exhibition 2014 IP Camera industry momentum to do simple induction.
Domestic surveillance manufacturers counter-attack
HD or use the vast majority of early applications in the financial, public security , campus , and other high-end smart city areas , mostly encountered competition or domestic brands. Analog era , the underlying core technology controlled by foreign manufacturers , Chinese manufacturers are basically production assembly . Into the digital high-definition era, more and more manufacturers have written 3A algorithm , master network camera clarity , color , focus , exposure and other technologies. In addition, the digital high-definition era, as a competitive high-definition monitor manufacturer , is best able to provide the IPC, NVR, Hybrid DVR, decoders, and other platforms supporting a full range of products and solutions , rather than the only IPC, it is precisely this point , the domestic manufacturers greater advantage , and today the country has done a DVR and HD video surveillance software manufacturers do before . In contrast , some foreign manufacturers of pure IPC only IPC, can not be packaged supporting sales , manufacturers need other HD NVR, compatible decoder to them .
IPCamera more intense price war in the future
From the current domestic market, surveillance cameras ,HD IP Camera sales continue to increase , analog cameras declined. At present, many cities , such as peace , peace villages , safe campus , bank monitoring bidding projects require IP HD cameras with a resolution of 1280 × 720 or more, and in many areas due to civilian control IP high-definition picture quality, wiring is simple, comprehensive cost advantage of low user acceptance .
Digital HD with IPC to many security companies has brought new opportunities , we face a re- race , many manufacturers hope that a new era of high-definition digital transfer , or hope to achieve greater sales in major reshuffle in the new high-definition era , more focused technology . R & D strength of enterprises to take advantage of high -definition technology threshold , high starting point , the lack of technical research and development of high-definition analog processing block outside the door . As enterprises gradually mastered the core technology IPCamera cameras , more easily personalized and differentiated , thus avoiding the homogenization of vicious price war . Compared with the analog era , the era of digital high-definition is more conducive to the development of enterprise development . IPC will face the same price wars and DVR era , and even more violent times faster than the DVR price war came . After experiencing a war, the industry will return to a peaceful , industry will be more orderly, industry rules, more rational norms , profit rationalize the division of refinement, have their own strengths . Finally, the number of manufacturers from a few thousand to more than a dozen , or even less.

Analog-to- network , high-definition monitor is a complete technical concepts
For monitoring system, HD is a complete technical concept , from image acquisition, conversion, compression, transmission, storage, control , and display a complete image processing . And on the whole video monitoring system, front-end image acquisition device that the camera head , is the core of the whole system, or the entire system can be likened to the "eyes ." If there is no front camera lens , video surveillance can not be achieved , just as human eyes can not see everything in the world is no different . If there is no front camera lens , the monitoring system will not be able to capture high-definition video surveillance images.

IP Camera civilian market surge
IP Camera civilian market surge
With the rapid development of network video surveillance , public and civil surveillance market surge in demand for the security industry has brought more opportunities and challenges. 2013 , speed the development of civilian control of the market, so that the newborn IPCamera ( network camera ) has become the hottest video surveillance products , spawned a series of innovative security companies.
A prediction : IP Camera surveillance market absolute advantage in the future
China has experienced analog video surveillance market surveillance , digital surveillance and network monitoring three main stages , with analog control , digital surveillance is not the same , in addition to rely on the development of network monitoring utility market , the civilian market , such as small and medium enterprises , factories, supermarkets, convenience stores , strong demand for family and other users , played an indispensable driving force.
According to authoritative statistics , in 2012 the global market surveillance equipment shipments of up to 90 million units, which accounted for 9.9% of IPC . As from analog video surveillance market surveillance monitoring, network monitoring figures to a successful transition stage , this proportion or will quickly pulled . Trend, network video surveillance equipment has become the middle and lower reaches of security companies must grasp winning "sword ."
Second, the problem : The network created everything , opportunities and challenges of IP Camera
Unprecedented popular Network Camera , IP Camera dazzling array of products on the market , in the form of all sorts , but it varies greatly , the prevalence of several disadvantages :
1, the exchange of visits between different network operators is very slow, not even remotely browse view . For example , the user's IP Camera via telecommunications Mobile, China Unicom 3G view , very smooth or video can not be viewed , giving users a great deal of inconvenience ;
2 , the user can not truly "zero setting " use , the average user to log into the device , to the appropriate network devices can be used to set the rear ;
3 , generally , "the hard light, soft ," the industry , end-user experience is poor, inconvenient and complicated to operate other shortcomings affect product sales.
Network video surveillance era, mainly from the public market to the civilian market is gradually expanding opportunities ; from the technical to the service , users must go through every aspect of the test , a challenge.
Third, solution providers : waving a magician, let IP Camera more humane
