Dahua to launch HDCVI cameras

November 2013 News

Dahua Technology is releasing High Definition Composite Video Interface (HDCVI) technology. HDCVI offers a fast and easy upgrade to high definition under conventional cabling environment. The in-house technology – HDCVI – features over-coaxial-cable analogue HD video transmission, allowing reliable long-distance HD transmission at lower cost.

The highlights of HDCVI are the following:

Easy upgrade to HD

HDCVI technology renders 1080p and 720p HD video format by analogue modulation; which means that the new solution inherits exactly the same installation and deployment as the conventional analogue ones, only offering megapixel high video quality with more details retained.

Long-distant transmission

Due to the fact that it is transmitted over-coax, HDCVI could realise reliable long range and non-latent transmission without further relay devices. For the comparison with HD-SDI at the transmission front, HDCVI shows a distinguished advantage. With general transmission media, HD-SDI reaches 100 metres at most while HDCVI, at least, transmits 500 metres by using 75-3 cable and featuring low signal distortion rate.

No latency

HDCVI is more reliable as it adopts P2P transmission. Meanwhile, it features no latency for an outstanding real-time performance and it requires no compression, which successfully maintains the original quality and thus present in vivid images.

Three signals over one cable

In addition, with three signals – video, audio and control – composited in one cable, the solution could further simplify the cabling while ensuring a smooth transmission at the same time.

In a word, HDCVI is an industrial breakthrough that offers megapixel image quality over long-distance transmission while enjoying the simplicity of installation.
