Network High-Definition Cameras Several kind of technical analysis

With the development of monitoring technology constantly improve,  the requirement of monitoring system  not only stays in the "visible", but rather to "look"."HD" can be said to be the hot topic in the industry in recent years, HD as one of the main development direction of monitoring technology development, the products on the market emerge in endlessly, companies are jostling to introduce their products and solutions, many HD technology development and application has also been appeared and IP, HD-SDI, HDCVI, SLOC technologies such as high-definition cameras.

     IPC: hd consistent monitoring of IP network monitoring is regarded as the main trend in the future video network monitoring, judging from the current domestic market surveillance cameras, IP hd camera sales continue to increase, analog camera showed a trend of growth.Many such as safe domestic cities, transportation, safe campus, bank monitoring, etc. But the biggest advantage of hd network video monitoring is based on three points :the IP data transmission, storage and processing

     HD-SDI digital high-definition cameras：HD-SDI is high definition digital component serial interface, HD-SDI camera is to adopt HD-SDI digital signal is uncompressed format in the line of video transmission, therefore is a kind of real-time transmission of video compression high-definition video camera.HD-SDI system is a kind of model with SDI serial number on the coaxial cable transmission of video signal digital HD video monitoring system.

   SLOC (SecurityLinkoverCoax, coaxial cable safety link) is a kind of composite video transmission technology, through a coaxial cable transmission analog video and digital video at the same time.SLOC technology is simulated and the advantages of the IP system in one of a kind of transmission technology.The SLOC technology can achieve up to 500 meters long distance transmission;At the same time, greatly convenient for hd IP camera in the original CCTV coaxial cabling infrastructure.

    HDCVI as a new generation of coaxial hd technology is produced with the development of hd market, compared with the traditional simulation, HDCVI as millions of pixels of coaxial high-definition technology has certain advantages in image quality.Dahua shares (002236, shares) independent research and development of simulation of high-definition HDCVI solution, using analogue modulation technology transmission line by line (Progress) scanning image signal, of which 1920H(1640 x9600) resolution belong to high definition video signal.HDCVI popularity today is no longer simplification the front end of the storage products, continued to improve and enrich DVR and front-end products at the same time, Dahua now have multiple optical transceiver, matrix series solutions, distributor, controller, etc.At the same time products is increasing perfect, HDCVI as a new generation of coaxial high-definition high-definition technology And network has many advantages.

   Hd is widely recognized, is the inevitable trend of industry development.What are the advantages of HDCVI?

1.Convenient deployment: HDCVI system is plug and play, simple and pure.Hardware circuit connected after, can use the system, is the most easy-to-use megapixels hd system.

2.Real-time and reliable:HDCVI don't need to code, realize  no delay, the analog demodulation technology, line by line, video frame by frame transmission, real-time degree is superior to the IPC, and has a unique coding technology, video effects, bright color reduction degree is high, the real hd.

3.High safety: HDCVI technology is Dahua hd coaxial technology with independent intellectual property rights of millions of pixels, has been HDCCTV alliance into the international standard for high-definition video.HDCVI system and simulate the system, is a closed loop transmission, the unopened system.The benefits of t video security is very large.

 4. Convenient transformation: the simulation of the monitoring system of laying cable is a coaxial cable, and at 75--3 or 75-5 cables are mores.The coaxial cable buried underground, through the wall, some through the road, some under the water.If, in the renovation project lay cables again, thinking is a very headache thing.
