 Sixteen ports video signal SPD: NKP-TEL-4U

Product description

The product is applied to video surveillance systems, matrix BNC connector, Optical BNC interface, the camera BNC interface lightning surge protection. It can effectively prevent overvoltage and current which are induced by lightning or industrial noise and other factors, and other transient surge voltage on the system or equipment or cause permanent damage or momentarily interruption and other hazards.

Apply to monitor system, (such as video matrix switchers, cameras, video surveillance equipment, video distributor, etc.) video line surge protection.
