Comparing HD-CVI, HD-SDI, and IP Systems

Highlights:

   What is HD-over-Coax exactly?
 HD-over-Coax, or HD-CVI (High Definition Composite Video Interface), is an over-coaxial-cable analog HD video transmission standard developed specifically for the CCTV industry. HD-over-Coax composites video, audio, and control signals together and then transmits them over one coaxial cable, simplifying installation. Using RG-59 cable, HD-over-Coax transmits HD video over distances in excess of 500m (1640 ft.) with no expensive repeaters or signal boosters (more details below).
​ 
​   The HD-over-Coax solution incorporates both cameras and DVRs. The technology currently offers two specifications: 1080p (1920 x 1080) and 720p (1280 x 720). In addition, the technology features Auto Signal Compensation (ASC) which provides extremely low signal distortion for long-distance transmission.

Upgrade your current analog security system to the same high definition you see on your favorite TV show!

Mega-pixel cameras at a fraction of the cost of traditional IP… 
​
No doubt IP images provide high quality results, but the cost of IP can in some cases be beyond a client’s budget. But what if you could get digital mega-pixel quality systems integrated with your analog cameras and leverage your existing infrastructure?

​  
​HD-CVI is here! (High Definition Composite Video Interface).
​
HD-over-Coax is a new analog high definition (HD) video standard transmitting over coaxial cable. The technology provides transmission of HD video as well as audio, and two-way control data over long distances. You can implement an HD system using the same coax cables that your existing analog system is running on. HD-over-Coax installs just like analog cameras and gives you up to 1080p High Definition. No fiber, no configuring, no licensing & no special training required. And, you don't have the limitations on distance like you find in IP and HD-SDI systems.
