ABSTRACT:
The system integrates a CCTV system including one or more video source units into the structured cabling system (“SCS”) of a building or the like by combining video signals, control signals and power for each video source unit over a single multipair cable made up of plural unshielded twisted pairs (“UTP”) of insulated copper conductors, so that one twisted pair of the cable carries the video signals, one pair carries the control signals and one or two pairs carry the power. The system includes combiners and distributors which can interface with the SCS cable through standard modular, multi-pin plug and jack connectors.
