Video Ground Loop Isolator The Video Ground Loop Isolator are passive devices which reduce Ground Loop Interference with CCTV signals and can easily install in a new or added to existing systems.It is useful where a video signal is transmitted via cable between points with different ground potentials, Differences in ground potentials are typically caused by unbalanced power line loads.Coaxial Video Ground Loop IsolatorFeatures:BNC male to BNC female with mini cable 25 on both sides.Passive, no power required.Prevents video-signal distortion caused by video ground loops.Eliminates picture tearing, cross talk and rolling.Prevents power cables laid by others interfering with the CCTV system.Built in TVS ( Transient Voltage Suppressors) for surge protection.Coaxial Video Ground Loop Isolator built in filterFeatures:BNC male to BNC female with mini cable 25 on both sides.Others same as Ground Loop Isolator function.Built in Video filter, perfect to work with DVR to immunity DVR interference, for extra interference rejection.Built in TVS ( Transient Voltage Suppressors) for surge protection.TGP600 Twisted Pair Ground Loop Isolator Features:BNC male to terminal block with 15cm mini coax cable.Passive type, no power need.Hi Performance to eliminate ground loop problem.Low video loss , Bandwidth: 20hz -11Mhz ,+0 -3Db.Prevents video-signal distortion caused by video ground loops.Eliminates picture tearing, cross talk and rolling.Prevents power cables laid by others interfering with the CCTV system.Installation ViewThe Video Ground Loop Isolator should be installed where runs of video cable are known to have ground loops. It must be installed in the video cable that has come directly from the camera, but before the cable has been connected to anything else.If several video cameras come from the same area, fix a Video Ground Loop Isolator In every cable, or a ground loop will still remain.
