VB43F Overview:
The Nitek VB43F video balun transceiver for twisted pair up to 1,000 feet (750 feet when used with DVR equipment).

The cctv video balun combiners are unique transmission devices that provide an economical means of sending video, security camera power and RS422 over a standard Cat 5 cable. A basic cctv system requires one unit at each end of a 4-pair Cat 5 cable. Video is sent over one pair, RS422 over a second pair and cctv camera power can be sent over the two remaining pairs.

A female BNC connector provides video input or output and two 2-screw terminal strips are provided to connect RS422 control and power, respectively. Connections to the Cat 5 cable are made via RJ45 connectors on the VB43F and via punch-down terminals on the VB43FPD. The VB43F cctv video baluns provide the same high immunity to noise and interference as all of the Nitek baluns.

The unique design of the VB43F 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.

■ Quality video over ordinary twisted pair cable
