Product Description
The VH3239 is a 32 port video balun hubs with built-in surge suppression. Systems operate with other Nitek UTP video equipment including, video balun hubs, standard video balun transceivers or active receivers.
The VH3239 video balun hubs are multi-channel 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 VH3239 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 VH3239 is designed to provide superior immunity from noise and interference, such as RFI and EMI.
Features
• 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
