This product is suitable for the monitoring of the camera's video signal lines, control lines and power line of lightning surge protection. It can combine the
above mentioned lightning protection function into one. Its housing adopts integrated aluminum-alloy structure with small volume and ultra low residual pressure output.Its design is fully considered that the electrode capacitance and distributed capacitance would lessen data signaling with small insertion loss which can satisfy
the requirement of video signal transmission and Has the advantage of quick response to transient overvoltages.
