CCTV Pass-Thru Balun
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).
Features/Benefits
Combines video, power and PTZ control under one 4-
pair Cat5e/6 cable for more efficient cabling
