• SPDs for CCTV is mainly used for supervisory control system, preventing product from lightning
strike and surge.
• Protect the video equipment effectively and ensure the image can display normally5.Inhibit the
overvoltage pulse issue fromthe transmission line on the camera effectively, Avoiding the video
surveillance equipment damage due to overvoltage pulse.
• Offer surge protection for almost any products application in power, instrumentations and controls,
network and data lines, coax and etc.
• For Radio Antennas, GPS Antennas, CATV, CCTV and Satellite TV.




• Lower Prices
• Low Capacitance
• High Discharge Current
• Continuous and repeated protection in intense environment



1,Protect electric system and on-loading electrical apparatus from thunder and instantaneous over-voltage.
