Features

• BNC male to BNC female with mini cable 20cm on both sides.
• Passive type, no power needed.
• Hi Performance to eliminate ground loop problem.
• 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.

Any kind of accessory such as electric motors and lights that are grounded to the ground loop isolator body will result to varying voltages across the body of the vehicle or conductor. If the voltage coming from the amplifier ground to the head unit ground could be measured, there would be a very slight voltage difference although they are both grounded. Worse, the small pulses are also produced by the alternator that is not filtered out entirely by the capacitors and/or battery. These minute pulses make noise, which varies with the alternator speed. A ground loop isolator schematic diagram could explain the concept more clearly.

Ground Loop Isolator for Video and CCTV

There is also a video ground loop isolator that can be used for CCTV camera applications and coaxial cable. The device has a BNC male to female input and output. The isolator is passive so it does not require any power input. The idea for the coaxial ground loop isolator is to prevent distortions of video signals resulting from video ground loops. The device reduces CCTV interference signals caused by ground loops and can be installed easily in a new CCTV camera system or to an existing one. The ground loop isolator for video/CCTV can be used if a video signal is transmitted by way of a coaxial cable through points that have varying ground potentials. The different ground potentials are usually caused by power line loads that are not balanced.

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.
