UTP Balun for video, audio and power supply.
UTP Balun is a video balun set which consists of two unpowered devices that convert BNC signals to send out over a data/UTP cable, at the other end is the other device to convert the signal back to BNC.
Also, the distances that can be achieved for good transmission over UTP cable are many times longer than when using coaxial cable.
With coaxial cables, in some cases an amplifier must be used after 100 meters because the image strength is weakened too much with this balunsset you do not suffer and distances of 400 meters are no problem.
