The ground loop isolator can only be used on the DVR side, and if used on the HD camera side then there will be no video.
Once the signal passes the isolator, it will become a clear video picture, without any ghost. It is widely used in various security monitoring system. No power, easy and convenient installation, and high performance.
The video ground loop isolator should be installed where video cable runs are known to have ground loops. It must be installed
on the video cable at the DVR end that has come directly from the camera, but before the cable has been connected to the DVR.
If several video cameras come from the same area, fix a video ground loop isolator in every cable, or a grounded loop will remain.
