CCTV Power-Thru Balun

500024, 500029

_____________________________________________________________________________________

Overview

The CCTV Power-Thru Balun allows video and
remote power to be transmitted via one 4-pair Cat 5
cable, thus eliminating the need to install multiple
cables for more efficient cabling in the CCTV
security and surveillance environment. There are
two models: 500024; with modular RJ45 connector
and 500029; with screw terminals.

The Power-Thru Balun may be used in pairs or in
conjunction with MuxLab’s Passive CCTV Hub
(500130).
