Hybrid UTP power, video and data

July 2010 Surveillance

Steve Proctor, sales director at Network Video Technologies (NVT), expands on the company’s hybrid capability.

The transmission of video using unshielded twisted pair (UTP) cable is nothing new. Network Video Technologies (NVT) offers solutions that are credible, cost-effective and future-proofed, in that its use of UTP creates a genuine hybrid solution; whether deploying composite video, networked video or a combination of the two – they use the same structured cabling infrastructure.

At the top of any security installers’ wish list has always been the goal to embrace any way of reducing the time spent pulling cable while also enhancing the overall performance of their security solutions.

NVT’s early products transmitted video and audio signals over UTP cable, but the products have developed over the years and today we are not just talking about transmitting video signals. UTP cable can also be used to transmit low-voltage power and telemetry data, and that equates to some serious savings in terms of both time and money for installers.

Another point to remember is that a UTP infrastructure can be used for both composite video and IP-enabled video. If you use UTP today, not only will you save money and time, but your system can also be converted to an IP-enabled solution without replacing the cabling.

The hybrid approach

NVT offers a very wide range of UTP-based solutions, including new Digital EQ hubs, Power, Video & Data (PVD) power supply hubs, power supply passive receiver hubs and multimedia products. The PVD hubs supply low voltage power (24 VAC and 12 VDC), meaning that localised power supplies and electrical outlets are no longer required at each internal camera location. As well as handling the distribution of power, UTP cable also supports video transmission while additionally delivering PTZ telemetry data, all over a single four-pair Cat5e cable.

All NVT products are UL, cUL and CE listed, RoHS and WEEE compliant, and backed by a lifetime warranty.

The NVT PVD solutions offer real-world benefits to installers, and to assist, NVT offers an Applications Guide to its entire PVD range. Devised to help installers to get the most from UTP based transmission, it details how all CCTV camera power, video and data feeds can be supplied using just a single cable.
