This CCTV Video Ground Loop Isolator reduces “Ground Loop Interference” within CCTV signals and can easily be installed in new or existing systems. This unit is useful where a video signal is being transmitted via cable between points with different ground potentials. The differing ground potentials can cause the ground loop interference, and in turn can distort your CCTV feed.


This particular unit also has the added benefit of doubling as a Passive BNC Video Balun Transceiver over CAT5e/6 Cable. Disconnect the female BNC pigtail from the “press-fit” terminal block and you will be left with a BNC Video Transceiver Balun. Simply terminate your CAT5e/6 cable in the screw less terminal block. The ground loop interference rejection will work the same whether you are using the female BNC or the CAT5e/6 cable.




Connectors: BNC Male to BNC Female with mini pigtail cables on each side
