DITEK’s DP4P protects all the sensitive feeds to critical Pan/Tilt/Zoom cameras, not just the video cable. Simple to install, the DP4P protects 24 Volt power conductors, 5 Volt RS-422 data pairs, and coaxial conductors – all in one compact package. With the lowest video let through voltage (and best surge protection) on the market, the DP4P provides ideal surge protection for today’s sensitive, sophisticated PTZ cameras. Models are available to protect BNC Coax, Balun, and Twisted Pair video.
