CCTV Pass-Thru Balun

500022

_____________________________________________________________________________________

Overview

The CCTV Pass-Thru Balun (500022) allows video,
remote power and 2-wire PTZ control signals to be
transmitted via one 4-pair Cat5e/6 cable, thus
eliminating the need to install multiple cables for more
efficient cabling. The CCTV Pass-Thru Balun may be
used in pairs or in conjunction with MuxLab’s Passive
CCTV Hub (500130).
