4 Port Active UTP Video Mini-Hub

The Nitek VH456 4 port active video mini-hub with gain and loss control, built-in surge suppression, ground loop isolation and video detection. Systems operate with other Nitek UTP video equipment including video transceiver hubs, standard video balun transceivers, active transmitters or any twisted pair equipped camera. These active video mini-hubs are multi-channel video receiver devices that provide a low cost means of receiving 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 VH456 can be used on video runs up to 1,500 feet (450 meters) when used with passive transmitters. These hubs provide superior immunity from noise and interference, even when run in common raceways with AC.
 

VH456 features include:

  • Quality video over ordinary twisted pair cable
  • Built-in surge suppression
  • Built-in ground loop isolation
  • Convenient access to DIP switches for accurate gain and loss control
  • High immunity to noise and interference
  • LEDs to indicate video detection
  • Compact design
  • Video can be run in the same cable with telephone, computer signals and power
