DESCRIPTION
Our Video Ground Loop Isolator is a necessary part of every CCTV setup,
providing improved security from troublesome ground loop distortion.
Installation of the Video Ground Loop Isolator rescues you from the
irritation of tearing apart your setup as you search for the source of
irritating signal disturbances such as those caused by loops or wiring
laid too near power lines.
The product also provides for better surge protection, while convenience
of installation means the Video Ground Loop Isolator is easily added to
previously existing operations.
Why has my system such problems ?
An earth loop interference may occur when there is more that one ground or
earth between two pieces of equipment. Because there is multiple ground
paths, loops are formed in which current can flow.
The current flows through the shield of coaxial cable and it picks the
interference up and carries it to the inputs of CCTV equipment. This
equipment interprets this interference as part of the video signal and
displays it on the monitor as a rolling ¡§hum bar¡¨.
How works the ground loop isolator ?
The ground loop isolator terminates ground loop currents in a cable and
blocks the hum and interference carried in the ground loop.
