Video baluns convert the impedance of an analogue CCTV video signal from the 75-ohm coaxial standard to the differential twisted-pair format suitable for Cat5/6 UTP cable, allowing structured cabling infrastructure to carry CCTV video signals in place of dedicated coaxial cable.
In buildings where Cat5/6 cable is already installed throughout, video baluns allow the existing network cabling to carry CCTV cameras to an analogue DVR without running additional coaxial cable. This is particularly useful on retrofit installations in commercial buildings, schools, and offices where structured cabling is already in place but coaxial cable is not.
At 4K capability, these baluns support the highest current resolution of analogue CCTV cameras over the twisted pair infrastructure, ensuring they are not the resolution-limiting component in a 4K analogue camera installation.
Screw terminals accept stripped cable ends directly, making them the appropriate choice where the Cat5/6 cable is not pre-terminated with RJ45 plugs, or where the installer prefers a screw connection for reliability in a permanent installation. A pair of baluns is required at each camera run: one at the camera end and one at the DVR end.
For CCTV installers working in buildings with existing Cat5/6 infrastructure across London and the UK where 4K analogue cameras are to be connected over UTP cable, the screw-terminal 4K video balun is the correct passive transmitter for this installation method.
Key Features
