1PC High Performance Video Ground Loop Isolator Filter – BNC

Video Ground Loop Isolator could 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.

Troubleshooting: Electromagnetic Interference = EMI

Ground loop interference is caused by EMI. When there is large difference in ground potentials between two points EMI may occur. Differences in ground potentials are typically caused by unbalanced power line loads, and the peak-to-peak magnitude may vary from 0 volts to more than 10 volts.

Using Ground Loop Isolators may help prevent EMI. Ground Loop Isolators reduce the interference between the camera and the DVR by producing equal and opposite magnetic field that cancels one another. It is often recommended to use the Ground Loop Isolator at the DVR end. Also our Ground Loop Isolators has built-in Wave / Interference Rejection and Noise Filter.

Note: If that does not solve your ground loop interference it is suggested that you change your power supply. Or if the camera is dual power, change to 24V AC.
