Description: The video ground loop isolators 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. Our product is a great solution to prevent video-signal distortion caused by video ground loops. Features: 1. 100% brand new and high quality. 2. BNC male to BNC female with approx. 22cm cable on both sides. 3. Passive, no power required. Plug and play. 4. Prevents video-signal distortion caused by video ground loops. 5. Eliminates picture tearing, cross talk and rolling. 6. Prevents power cables laid by others interfering with the CCTV system. 7. Built in TVS (Transient Voltage Suppressors) for surge protection.
