16 Ports - Up To 750 Feet, (RJ45 Jacks)
The Nitek 16 port video balun hub VH 1639M with built-in surge suppression. Systems operate with other Nitek UTP video equipment including, single or multi-port video balun hubs, standard video balun transceivers or active receivers. The VH1639 is appropriate for all CCTV applications using standard Analog type cameras.

The VH-1639M 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 VH1639 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 VH1639 are is designed to provide superior immunity from noise and interference, such as RFI and EMI.
