8 Port UTP Video Hub

The Nitek VH839M video balun hubs are multichannel video transmission devices that provide a low cost means of sending quality live video over Category UTP cabling. The systems can also adapt to existing communication and computer network spare pairs, or new cable installations. The VH839M can send video up to 750 feet (225 meters) when used with other products in the VB37 or VB39 family. When used with model TR515 or TR560 active receivers, distances of 1,500 feet (450 meters) and 3,000 feet (900 meters) respectively, can be attained. The VH839M is designed to provide superior immunity from noise and interference, such as RFI and EMI.

VH839M features include:

  • Quality video over ordinary twisted pair cable
  • Built-in protection from power surges and transients
  • High immunity to noise and interference
  • Passive units require no power
  • Video & P/T/Z over a single pair with “up-the-coax” systems when used with passive baluns
  • Highly compact, only one rack unit in height
  • Conveniently integrates with Nitek Modular systems
  • Video can be run in the same cable with telephone, computer signals and power
