Twisted Pair

A video balun (balun = balancer/unbalancer) converts the video signal from an analog camera, intended to be transmitted over a 75 Ohm coaxial cable, to transmit it over a UTP cable (100 Ohm).

A 4, 8 or 16 channel balun switchboard serves to make it easier to receive several baluns at the recorder end, resulting in a cleaner installation.
