Coaxial two-way control

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. HDCVI technology is a cost effective solution that allows for a more complex installation, based on existing RG-59 coaxial cable, HDCVI Technology can transmit HD over analog in 1080p up to 300m and 720p up to 500m.

 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 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.

  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.

Analog systems based on coaxial cabling still dominate today’s video surveillance market, however the demand for high definition is increasing. The need to change out the cabling for an HD system can result in higher operational costs for our clientele. HDCVI technology is here to bridge the gap and give a high definition solution to those with an analog system already in place. No new cabling is required when upgrading existing analog systems to high definition when you are using HDCVI Technology.

HDCVI Compared to Other Technology

Why choose HDCVI?

Easy upgrade to HD1080p & 720p
Progressive video
Long Distance Transmission: HDCVI=500m v.s. HDSDI=100m
Compatible with standard video balms
The Importance of Cable Type:
Transmitting data 500m over a coaxial cable can be realized, depending on the cable selected. Cable 75ohm-3mm (diameter) and 75ohm-5mm are recommended for transmissions within 300m, cable 75ohm-5mm and above for over 500m. Connectors and welding process also affect the transmission distance. RG59 coaxal cable= 75ohm-6mm
