DESCRIPTION

The ZTR-4AC is designed to video signal transmission via twisted-pair cable. Video signal and data need two pairs from the cable, and the remaining two pairs are utilized for AC or DC power sending.

The device is equipped with video balun which adapts the impedance of symmetrical line to the impedance of coaxial cable 75Ω, ensuring video transmission up to 400 meters. The video lines are protected by diodes and the power lines by varistors.
