HANGZHOU, China /October 21, 2013 — Dahua Technology releases High Definition Composite Video Interface (HDCVI) technology. HDCVI is the technology breakthrough in the industry, offering the fast and easy upgrade to high definition under conventional cabling environment. The in-house technology — HDCVI — features over-coaxial-cable analog HD video transmission, allowing reliable long-distance HD transmission at lower cost, while complex deployment is applicable.
The highlights of HDCVI are the followings:
Easy Upgrade to HD
HDCVI technology renders 108op & 720p HD video format by analog modulation; which means that the new solution inherits exact the same installation and deployment as the conventional analog ones, only offering megapixel high video quality with more details retained.
Long-distant Transmission
Due to the fact that it is over-coax transmitted, HDCVI could realize 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 meters at most while HDCVI, at least, transmits 500 meters 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.
3 Signals Over 1 Cable
In addition, with three signals — video, audio and control — composited in one cable, the solution could further simplify the cabling while ensure a smooth transmission at the same time.
In a word, HDCVI is an industrial breakthrough, a revolutionary technology that offering megapixel image quality over long-distance transmission while enjoying the simplicity of installation.
