CCTV Video Ground Loop Isolator For CCTV System (GB200)
CCTV Video Ground Loop Isolator for CCTV System (GB200)Description:The Video Ground Loop Isolator GB200 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.Features:1.?BNC male to BNC female with mini cable 15cm on both sides 2.?Passive,Website:, no power required 3.?Prevents video-signal distortion caused by video ground loops4.?Eliminates picture tearing, cross talk and rolling5.?Prevents power cables laid by others interfering with the CCTV system6.?Built in TVS (Transient Voltage Suppressors) for surge protection7.?Built in Video filter, perfect to work with DVR to immunity DVR interference, for extra interference rejection8.?Others same as Ground Loop Isolator function9.?Weight: 60g/pcTechnical specifications:Insertion Loss0.5dBFrequency Response20HZ- 10Mhz,+0/-3dBInput Resistance75 ohmOutput Resistance75 ohmIsolation Voltage600VDC (Min)Insulation Resistance100M OhmTransient Voltage Suppressor12 VrmsDimensions (mm)60*30*20 with 15cm*2 cableMaterialABS BlackInstallation 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.Application Diagram
