Features: 100% Brand New and high quality Monitoring systems need to match the front of the camera the rear end of the monitor display image processor image storage systems and so different combinations of equipment. Because of the relative consumption of different devices require different voltage and current and thus affect the voltage potential difference the feedback from the ground impact interference conditions. The most common problem is the impact of interference twill using a series of ground network cable company interference products can easily exclude this interference eliminating the project is completed but could not be approved because of the impact of interference significant distress closed 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 Specifications: Surge protection: 4KV Joint mode: BNC Female (Video signal input port) BNC Male (Video signal output port) Power supply: No power required plug and play Color: Black Package Includes: 1 * Coaxial Video Ground Loop Isolator
