Multi Channel Long Distance Coaxial
The Multi-Channel Long Distance Coaxial (MCLDC) camera using existing analog coaxial cabling, allowing up to 16 cameras to share a single cable at distances up to 1000 feet. Unlike HD-SDI, which uses coax but sends uncompressed data and limits resolutions, the MCLDC transmits H.264 or JPEG using standard advanced digital television channels and can run at resolutions and frame rates greater than IP.
