1. This product is for coaxial cable video transmission interference, attenuation and other problems developed a powered device, including the transmitter (front-end) and the receiver (the back end), can effectively eliminate the surveillance video signal transmission process various strong electromagnetic signals (such as intense pulsed radio antenna, frequency converters, motors and other electrical power caused by) the formation of the interference of the video signal, such as image jitter, image distortion, image textured, Gantt, snow, etc., to ensure stable image quality, reliable transport.
2. The main application environment interference field elevators motors, transformers, substations, transmission towers, power plants, workshops and other.
3. Main purpose: video interference elevator video interference fields, factories motor disturbances, television or video interference and other nearby towers, surveillance video signal interference problems caused by long-distance transmission attenuation, along with the video signal transmission distance extension capabilities.
