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.
• BNC male to BNC female with mini cable 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.
