PVBX CABLING INFORMATION

CCTV cameras and VCR/DVDs have RCA outputs for NTSC composite video and analog audio. Most TV sets (Just about all sets manufactured in the last five years) also have separate RCA inputs for audio and video.

The PVBX Switch and expansion module both contain a 1024 cross point switch matrix. The PVBX controller can independently set each electronic switch. The switch is designed to transmit NTSC video and analog audio signals.

Coax RG59/RG6 cable can be used to transmit these signals. A separate line is required for audio and video. But, a better solution is CAT5 of CAT6 twisted pair cable. It’s less expensive, easier to run and multiple signals can be transmitted over a single cable.

A/V Transmission over CAT5/6 Cabling

Baluns can be used to transmit video over CAT5 cable but video quality suffers especially over long cable runs. The Video Modulator solves all of these problems with the added benefit of providing DC camera power. Differential video amplifiers transmits the video signal up to 1000’ over standard CAT5 cable.
