HD-TVI PTZ Cameras
HD-TVI PTZ Cameras: Pan-Tilt-Zoom cameras which offer 720p or 1080p HD resolution over coax cable. An additional pair of cables must be ran to control the camera, unless the camera and DVR both have UTC, or "up-the-coax" control. If no UTC, the additional control cable pair can be the 18/2 power cable of the Siamese cable, or a twisted pair UTP from a roll of network cable, or practically any other pair of cable.
