HDCVI the HD over Coax Solution

High Definition Composite Video Interface (HDCVI) Technology

HDCVI is HD video transmission using coaxial cable. This Technology allows for long distance HD transmission up to 1600ft. 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.

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.

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 
  • 3 Signals Over 1 Coaxial Cable: Video: Audio: Control data processing
Supports for:
720p @ 30fps, 1080p @ 15fps
Audio I2S input: 16bit@8Khz, 16KHz
Coaxial two-way control
