The CAMPDD24 is a multi-function surge protector for in-line coaxial video, two twisted pairs of data and the 12 or 24 VAC camera supply. The CAMPDD24 provides multi-stage surge protection to a single camera system and P/T/Z unit for each of these functions. The unit can be used at the camera or head-end. The CAMPDD24 is ideally suited for outdoor cameras, where extreme protection on all signal connections is required. The unit has BNC connectors at the input and output for connection to the coax and screw terminals at the inputs and outputs for connection to the power. The CAMPDD24 provides a heavy, single point ground connection and is easily installed in minutes.
