Single Channel AHD/CVI/TVI HD Passive Video Balun


The HD BALUN is a single channel passive video transceiver that mainly uses for solving the signal interference problem caused by potential source of interference. This device features super lightning protection and can be used for security monitoring system.

HD BALUN is compatible with all HD-TVI, HD-CVI and AHD analog camera.

The HD BALUN is both a transmitter and receiver featuring long transmission distance, good transmission effect and super interference rejection. It is widely used in various complex environments to prevent from interference.

Video signals can coexist in the same wire bundle as telephone, network or low-voltages power circuits. It is very economical and convenient to environment. Compared with traditional audio and video transmission products, the HD BALUN greatly reduces the cost and improves the performance.
