DTK-DP4P 
                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.  |
