Video Balun-Combiners for twisted pair ...
...up to 350 m (300 m when used with DVR equipment) in conventional UTP applications, 100 meters in TIA/EIA 568 applications.
The Video Balun-Combiners™ are unique transmission devices that provide an economical means of sending video, camera power and RS422 over a standard Cat 5 cable. Video is sent over one pair, RS422 over a second pair and camera power can be sent over the two remaining pairs. A female BNC connector provides video input or output on the VB43F and VB43FPD. A minicoax pigtail with male BNC is used on the VB43ATF. Two 2-screw terminal strips are provided to connect RS422 control and power on the VB43F and VB43FPD. Wires are provided for these connections on the VB43ATF. Connections to the Cat 5 cable are made via RJ45 connectors on the VB43F and VB43ATF and via punchdown terminals on the VB43FPD. The VB43F series Video Baluns provide the same high immunity to noise and interference as all of the NITEK baluns.
The unique design of the VB43F balun/combiner allows the combination of video, power and data in a 4-pair Cat 5 cable. This simplified wiring provides a convenient method of powering the camera, allowing for quicker and easier installations. The RJ45 modular jack uses standard 568B wiring so spare network cables can be used.
