UTP cabling has several advantages over its coax cousin: lightweight multi-pair UTP cabling allows multiple signals to be transmitted (up to one mile) along a single route and is much easier and more flexible to install. UTP has a higher immunity to external interference with commensurately better picture quality; it is also typically less than one tenth of the cost per signal compared to coaxial cabling. “Unscreened Twisted Pair (UTP) cable as an alternative to standard coaxial cable for video connections in a CCTV environment has been in use for some time, but its advantages have been consistently proven to the point that we will now be exclusively using UTP for all future major installs,” says Phillip Batten, CCTV Product Manager at CES. “The cumbersome nature of coaxial cabling makes it difficult to install, and difficult to run over larger distances,” Phillip continues, “which makes it expensive. It also tends to be affected much more by external interference and noise that adversely affects picture quality. “We were one of the first to adopt Twisted Pair several years ago, perhaps when the market wasn’t ready for it. Now things have changed, and customers are positively asking for Twisted Pair and specifically NVT technology, hence our decision to move away from coaxial for all future major CCTV work.”
