The Nitek Video Balun Transceiver for Twisted Pair VB39M video balun transceiver is a video transmission device that provides a low cost means of sending live video over unshielded twisted pair, point-to-point wiring for distances up to 750 feet. The VB39M is compatible with all of the up-the-coax control systems. A basic system uses (2) VB37 or (2) VB39 units, one at each end of a twisted pair of wires. These units are intended for use over existing in-house telephone wiring, Category wiring or other twisted pair cable runs to provide a convenient, costeffective alternative to coax. The VB39M is designed to provide superior immunity from noise and interference even when running next to line power!
VB39M features include:
- Quality video over ordinary twisted pair cable
- Built-in surge suppression
- Built-in ground loop isolation (When used with an active receiver)
- DIP switches for accurate gain and loss control
- High immunity to noise and interference
- LEDs to indicate video detection
- Highly compact, only one rack unit in height
- Easy to install and configure
- Video can be run in the same cable with telephone, computer signals and power
- Intra-building CCTV installations (instead of coaxial cable)
- Structured cabling (Category 5) environments
- To eliminate requirement for Plenum Coax
- Multi-camera applications through conduit (more cameras through a smaller diameter)
