Video Ground Loop Isolator
The GL1 Video Ground Loop Isolator is a passive device that reduces ground loop interference with CCTV signals in a new or
existing installation. Its useful when video signals are transmitted via cable between points with different ground potentials.
Also useful when interference is imposed onto Cat5 cable when video baluns are used.

BNC male to BNC male with mini cable 6” on both sides
Passive, no power required
Prevents video signal distortion caused by ground loops
Prevents interference from power cables being to close
Built in TVS (Transient Voltage Suppressors) for surge protection
Connection and Operation:
Connect the Video Ground Loop Isolator on the DVR side or cameras side pending best results and if cameras power comes
from different circuit than DVR power. Please follow the arrows on the Isolator for proper direction placement.
