HDO-1F-PRO is a 1-channel high-end protector for 75 ohm coaxial cable designed for high-definition video surveillance devices using AHD, HD-CVI, HD-TVI and Turbo HD signals ==”valign:sty=”-valign:s.” small;”>It uses 3 levels of protection that operate in the appropriate sequence during lightning strikes or other sources of both high and low voltage surges. During normal operation, the signal transmission circuits are not galvanically connected to the ground, so this does not create harmful ground loops or HD signal interference. The protection operation is based on the introduction of an electric charge into the circuits at an early stage of their formation, which delays the appearance of destructive voltage in the input circuits of video surveillance devices. When the main surge occurs, it is discharged to the ground through a separate conductor. Overvoltages occurring inside the wires and secondary surges are eliminated by a separate circuit separated by a special resistor. This results in a high resistance of the device to multiple impulses (stun guns) and ensures the appropriate sequence of operation of the individual protection stages.
