DTK-1TPV Twisted Pair Video Camera Surge Protector

DITEK Corp.
SKU: DTK-1TPV
DITEK's TPV series of video surge protectors address a key vulnerability of Twisted Pair Video CCTV systems - the video wire. Lacking even the minimal amount of protection that a shielded coaxial line has, Twisted Pair Video systems are vulnerable to surges entering on the unshielded video wiring, potentially damaging cameras, converters, or head end equipment. Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling outelectromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs. It was invented by Alexander Graham Bell. In balanced pair operation, the two wires carry equal and opposite signals and the destination detects the difference between the two. This is known as differential mode transmission. Noise sources introduce signals into the wires by coupling of electric or magnetic fields and tend to couple to both wires equally. The noise thus produces a common-mode signal which is canceled at the receiver when the difference signal is taken.This method starts to fail when the noise source is close to the signal wires; the closer wire will couple with the noise more strongly and the common-mode rejection of the receiver will fail to eliminate it. This problem is especially apparent in telecommunication cables where pairs in the same cable lie next to each other for many miles. One pair can induce crosstalk in another and it is additive along the length of the cable. Twisting the pairs counters this effect as on each half twist the wire nearest to the noise-source is exchanged.
