VB31AT

The Nitek Video and power balun combiner provides video and camera power over a single CAT5 for CCTV twisted pair video transmission up to 750 feet (225 meters) in conventional UTP analog Video applications, 100 meters in TIA/EIA 568 applications.

Product Description

The Nitek Video and power balun combiner provides video and camera power over a single CAT5 for CCTV twisted pair video transmission up to 750 feet (225 meters) in conventional UTP analog Video applications, 100 meters in TIA/EIA 568 applications.

The VB31AT is a unique UTP power and video balun which provides an economical means of sending video and camera power over a standard category cable. Video is sent over one pair and camera power is sent over two of the remaining pairs. A mini-coax pigtail with male BNC is used on the VB31AT. A pair of wires are provided for power connection. Connections to the Category cable are made via an RJ45 connector.

The VB31AT passive UTP power and video balun combiner provides the same high immunity to noise and interference as all of the Nitek baluns for CCTV transmission. This simplified wiring scheme provides a convenient method of powering the camera and allowing for quicker and easier installations. The RJ45 modular jack uses standard 568B wiring so spare network cables can be used. The VB31AT is a UTP transceiver that provides another Security Transmission Solution from Nitek.

Features

• Works with any HD TVI/CVI/AHD or NTSC and PAL
• Superior video over ordinary twisted pair cable
• Immunity to noise and interference
• Built-in surge suppression
• Passive devices—do not require power
• Convenient connection to Category cable for video and power
