CCTV balun
  • Product Number : Video & Power thru balun
  • Product : (Standard housing)

Our CCTV Video & Power thru balun is ideal to transmit power and video on a short distance. This balun will fit all cameras with a maximum power consumption of 300mA.

The CCTV Video & power thru balun allows video signals and remote power to be transmitted via a single unshielded twisted pair (UTP) cable for more versatile cabling.
The CCTV Power-thru Balun is used in pairs to allow you to eliminate more expensive coaxial cable, including coupling signals from remote video cameras to display systems, video capture, security and surveillance monitoring applications.
