Which camera and HD SDI million more cattle
With the continuous improvement of security technology, technical content security products is also greatly improved from the original CMOS to CCD, then from analog cameras into network camera , and from millions of ultra- high-definition network camera to SDI SD cameras . As video surveillance network camera manufacturers , if a little inattentive , will be followed by a new technology far behind.
Security camera industry because a lot of low-end products into the market . Most companies do start feeling was very difficult. Then high tide will follow. The market also spared a . Definition of further development, not only the front-end video capture device replacement has changed , thus bringing high definition video data traffic surge , but also on the back-end storage management equipment put forward higher requirements. It is said that the rapid development of high-definition , and finally inevitably encourage IP Camera replace analog cameras , NVR replace DVR, from the whole industry to see, HD network does have a distinct advantage , because in this era HD is an inevitable trend . But the industry also so few can really achieve positive overall solution , the lack of or a lot . Each company under various slogans and sang their own songs definition , small businesses also followed the booing , a price war will start , the market also shaken. What is plug and play, what remote viewing , and what low noise ? , And other customers with the future is not only to find what we want . In addition to satisfactory results during the day outside the definition of the other may only sing .
2012 HD-SDI camera turned out , making the field of video storage devices and the emergence of new opportunities and challenges, the network effect can be comparable to HD . Fully meet the high 200W1080P effect. Let us look to the eyes and HD-SDI and HD. Because the simple and convenient, and all aspects of analog cameras entirely consistent . So HD-SDI DVR storage needs in this definition came into being . In SDI-DVR surveillance system management device as more prominent advantages , first in the current platform compatibility with other devices is good , SDI cameras only through coaxial cable can directly access SDI-DVR, NVR did not like the video data after repeated compression and conversion , better contrast picture quality , but also to ensure stability as the traditional DVR . But the overall price more expensive than the high-definition network camera half.
After HD-SDI cameras to the network, the difference between analog cameras feature HD-SDI camera is a digital image signal obtained by the image sensor chip through the ISP to do image processing, is converted into uncompressed HD-SDI serial data, and then transmitted through the cable ; IP Camera after the image is also a digital signal obtained by the image sensor , and then do the image processing chip through an ISP , and then compressed and then transmitted via Ethernet . Since the HD-SDI camera without compression chip that can reduce the cost of this session .
If only from the point of view of the effectiveness and stability of the words . So SDI undoubtedly more dominant than the network cameras. But speaking from the words of the cost price , SDI cameras simply can not match. Now most of SDI HD cameras are just part of the Government and other projects to use. SDI to realize civilians, still have a long way to go. Therefore , we look forward to the next technology upgrades and updates to bring us more affordable and high- quality products it.

Analysis of trends in high-definition network camera image sensor used in
Analysis of trends in high-definition network camera image sensor used in
CMOS image sensors and CCD image sensors in the security surveillance all have their own market share, compared to CCD image sensors currently used , CMOS sensors because the image has the same or better performance , lower cost , higher integration , lower power consumption and faster speeds , but also to meet people now high -quality, good effects monitoring requirements , thereby increasing application in HD IP Camera , the CCD image sensor has gradually replaced the trend.
In the field of security monitoring , outstanding CMOS image sensor technology can achieve many new features and functions, and can provide critical differentiating features for the monitoring system OEM manufacturers. Moreover , the use of CMOS image sensor enables IP surveillance system to achieve a more economical and easier to install , which stand out in the market competition, thereby attract more customers. Now , there are already some monitoring system OEM manufacturers with forward-thinking is developing new, potentially large quantities , to produce their own surveillance market segments. Even a small office home monitoring system may only cost $ 100 , it can lead to over closed-circuit television system based on CCD image sensor larger markets.
Image sensor technology innovation inspires HD video surveillance market standards while turning the steering IP solutions , which can gradually from CCTV security camera solution. Full HD IP Camera provides a clear image details and better overall visual experience and information, but the intake of high -quality video , but require high frame rates and the ability to adapt to a variety of light from a high -contrast scenes in very dark conditions . To achieve high -quality, high -definition video requires a high level of innovation and extraordinary pixel technology .
CMOS image sensors used in high-definition network camera IP system must have a relatively high resolution, at 60 frames / sec high frame rates can be achieved 720P or 1080P. Although the standard video frame rate of 30fps, but 60fps frame rate camera manufacturers provide for greater flexibility , you can adjust the width of the shutter to capture fast moving objects within the scene .
One reason for the high-speed HD video HD IP Camera turned CMOS image sensor is an inherent characteristic of CMOS with lower power consumption . Lower power consumption CMOS image sensor incorporates many energy saving features such as clock gating design, variable frame rates and using CMOS process technology to achieve low standby current. In addition, digital or IP camera , the increase in the number of interface options , Gigabit Ethernet , HDCCTV and coaxial cable can be used as an interface to select IP and other high-definition video .
The latest trend is to integrate features wide dynamic range and wide dynamic range image processing on the image sensor to provide clear details and smooth video. Although the image resolution of today's surveillance camera system has been improving, but the pixel dynamic range but with reduced pixel scale and shrinking , thus limiting the surveillance cameras produce light distribution retains vivid images. To this end , it is proposed to achieve a wide dynamic range of the various pixels programs , including the number of pixels , horizontal overflow method, the multiple exposure frames and multiple exposure frame .
HD IP Camera many advantages of CMOS image sensors , can adapt to the rapid development of the security market is now in the modern people need a clearer , higher quality service , they both meet the needs of modernization , the market price is lower, there replace the CCD image sensor trend.

HD network camera application needs to resolve
Preface: from the current video surveillance market, network monitoring has been gradually integrated into the whole field of video surveillance , along with the entire network security industry and the rapid development of digital technology and the advance of the entire security industry has gradually across from analog to network, HD IP Camerahave gradually become the front-end video capture products industry leader .
Network cameras have SD and HD IP Camera , most of the standard definition network camera is in the traditional analog cameras IP module based on the increase , mainly to meet those requirements are not particularly high quality , but enables remote centralized monitoring It also can facilitate the construction installation and commissioning . In the current high prices relatively high , the market demand for standard definition IP Camera still occupies a considerable part of the share, like computer -based local area network for regional monitoring sites , such as residential areas, office buildings, stores , shopping malls, chain stores and other traditional monitoring the current standard definition network cameras mainly dominated ; partially across the region for remote monitoring via the Internet is also used to the standard definition network cameras, for example : children and elderly care is generally remote , unattended room monitoring , Internet monitoring and so on.
Fast development in recent years of network cameras is obvious , it is mushrooming rapidly , especially high-definition network camera .HD IP Camera have been able to rapidly develop in recent years, the most important reason is the market demand for video surveillance to enhance the quality , because the standard definition network cameras and traditional analog cameras are basically three or four hundred thousand pixels or less , Sony's latest EFFIO analog products are also programs around half a million pixels , these low -pixel camera products can not fully meet the needs of most customers . With the advancement of society as a whole , most of the customer demand for quality is not just to look , see, must also be monitored to see clear details of the screen, so the HD products nearly two years has also been very widely used. In recent years, the city of peace building occupies a significant proportion of HD products also been improved, especially in the safe city construction projects and other economically developed Pearl River Delta and Yangtze River Delta region , the demand for network HD products more intense . Not long ago, on a large project in Guangdong customers must be installed on a high-definition network camera monitoring every three to four points , frequent personnel access special places must also be installed high-definition network camera, we can see that the entire industry demand for HD products has been relatively clear.
Network video surveillance can quickly adapt to market demand, its biggest advantage is interoperability, remote monitoring and flexible networking. With the current rapid development of network technologies and services , broadband networks are rapidly toward every corner of the town. In this case , the network camera installation has no special wiring will be able to get quick and easy application , and more convenient than traditional analog surveillance equipment installed , while the construction cost of installing the whole project will be significantly reduced. In addition , convenient transport network , surveillance video images can freely switch between video monitoring , command centers or sub-centers of each video surveillance , making the overall monitoring and management and monitoring efforts have been comprehensively improved.
With the upgrading of the IP 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. By the government agencies and the public security organs leading safe city construction project is the number of products currently implemented relatively quickly and networking products are also used in a large field of network monitoring has been the first choice of most of the projects , in a recent safe City project on monitoring equipment are used in the vast majority of network cameras use SD and HD IP Camera with a way to achieve the integration of network coverage without blind spot monitoring projects.
In recent years, a number of major cities Beijing , Tianjin, Shanghai , Shenzhen , Guangzhou and other major traffic already on the roads, railway lines, large overpass , focusing on national road and motorway IP Camera installed in high-definition . Development of the industry but also gives us a metaphor in the near future, the network camera will get a very wide range of applications in the transportation industry . In order to achieve the overall regulatory control , the authorities will place traffic monitoring systems and national long-distance traffic monitoring systems integration as a whole, made a point to the surface , traffic monitoring system-wide network coverage of new intelligent control , this trend is also network cameras will be applied to achieve a major breakthrough .
Conclusion
With the rapid development of digital technology, network , network digital video surveillance video surveillance is bound to become a dominant force in the future , the market size of network camera will also be with the rapid development of the industry and the rapid increases in major domestic and from the current mainstream camera manufacturers development point of view, the network camera has become the core of the major manufacturers of competing products . However, the future development of the network camera exactly how ? Actual market demand will not be as good as people predicted ? It also requires the industry to jointly promote .
