CCHDTV technology is a world-class broadcasting video signal standard which complies with the non-hierarchical transmission specified in DVB-T systems. User can easily upgrade to 1080p and monitor CCHDTV video via DVB-T TV channels. Unitechno has developed and newly launched three new quality outdoor camera systems--TPC-100, TPC-200, and TPC-300 series, all embedded with CCHDTV technology.

This series of cameras supports 1.3 ~ 2 megapixel digital in/digital out full HD resolution over existing coaxial cable to save on installation costs for replacement projects. The TPC series outdoor cameras support digital video with H.264 compression (DVB-T standard) over one coaxial cable. Via one RG6/U cable, a camera  in this series supports video transmission for up to 1000 metres without separate hubs, repeaters, or injectors required.  This feature has been designed to save the user time at the installation stage and also provides savings on total cost of a system. With T connectors or splitters, the TPC series CCHDTV-inside cameras can be connected in series with up to 16 cameras in a loop.

The TPC series of cameras has been designed for analogue systems to migrate up to high definition quality with the possibility of internet access; they are ideal for the growing the replacement market today, worldwide.
