The most widely used form of twisted pair, and popular for that matter, is unshielded twisted pair (UTP). Generally, it’s beneficial for campus-wide use or applications that require a high concentration of cameras – casinos and school settings as two examples. UTP allows many communication protocols – voice, data and video – to reside in the same wire bundle.
When compared to other video transmission methods, UTP can hold its own. According to NVT, Menlo Park, Calif., when compared to coax, UTP offers total interference immunity, with most models with built-in surge suppression. Also, active models having built-in distance equalization control for crisp video at all distances can carry transmission distances up to one mile or more, say the techies at NVT.
