CCTV Balun
Power-thru Type Video and Power (Lead Free)

Part Number: BLN-PVRJ45

The CCTV Power-thru Balun provides the transmission of video signals and remote power via a single UTP (unshielded twisted pair) cable for more versatile cabling. The CCTV Power-thru Balun is used in pairs that allow you to eliminate more expensive coaxial cable, which include coupling signals from remote video cameras to display systems, video capture, security and surveillance monitoring applications.

The use of existing twisted pair infrastructure (such as telephone cable and cat. 5 computer networking cables) is also available. All of our Baluns are tested 100% for reliability and durability to guarantee your signal integrity.

 The CCTV Video Balun allows base-band composite video signals to be transmitted via a single unshielded twisted pair (UTP) cable for more versatile cabling. The CCTV 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.

The use of existing twisted pair infrastructure such as telephone cable and Cat. 5 computer networking cables are also available. All our Baluns are 100% tested for reliability and durability to guarantee your signal integrity.
