Video Balun Transceiver Card For Twisted Pair Up To 750 Feet (225 Meters)

The Nitek Video Balun Transceiver Card VB41x4 modular card is designed for use with the modular rack system. Each card has 4 video balun units, built-in surge suppression and video loss detection.

The Nitek video baluns are transmission devices that provide a low cost means of sending live video over unshielded twisted pair, point-to-point wiring for distances of up to 750 feet (225 meters). The Nitek video baluns are also compatible with all of the up-the-coax control systems.

A basic system would require one unit at each end of a twisted pair of wires. The Nitek video baluns are intended for use over existing in house telephone wiring, Category 5 wiring or other twisted pair cable runs to provide a convenient, cost-effective alternative to coax. Nitek video baluns are designed to provide immunity from noise and interference, even when running next to line power!

The VB41x4 plugs into the RK400 card cage, which holds up to ten (10) modular cards. The RK400 card cage is a powered card cage that accepts the full line of Nitek receiver units. This modular plug-in feature allows the system to be custom configured for each application and provides easy expandability.

VB41X4 features include:

  • Quality video over ordinary twisted pair cable
  • Built-in surge suppression
  • Immunity to noise and interference
  • Built-in video loss detection
  • Video & P/T/Z over a single pair (with up-the-coax systems)
  • RJ45 or push terminals for easy connection
