A balun is an electrical device that converts between a balanced signal (two signals working against each other where ground is irrelevant) and an unbalanced signal (a single signal working against ground or pseudo-ground). Transformer baluns can also be used to connect lines of differing impedance. The origin of the word balun is “balanced to unbalanced”.
Balun set is designed to transmit video signal with a twisted-pair cable. Placing the BNC connector on the cable, makes it possible to output the signal from the camera to a twisted-pair cable.
The device matches the impedance of 75Ω coaxial cable to the impedance of symmetrical line, ensuring transmission of video signal up to 400m (twisted pair category 5).
Pay attention to the correct connection of the positive (+) to (+) and (-) to (-). Reverse connection would cause distortion of the image.
