System handling video, control signals and power
First Claim
1. A system for operating a video source unit having a video data signal output adapted for coupling to a video receiving unit and a control signal input adapted for coupling to a control unit, the system comprising:
- a cable, including plural unshielded twisted pairs of conductors, a first coupling device at a first end of the cable for coupling a first twisted pair to the video data signal output and a second twisted pair to the control signal input, and a second coupling device at a second end of the cable for coupling the first twisted pair to an associated video receiving unit and the second twisted pair to an associated control unit.

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.
