Siamese Configurations and Paired Wires: I wanted to cover these first since the ideas of Siamese Cable, Siamese Configuration, and Paired Wire are applicable to all kinds, types, and gauges of wires. All these terms essentially mean the exact same thing. They all refer to a single cable that contains more than one wire. Closed Circuit Television (or CCTV) security camera installations typically use a three wire system. This system is commonly referred to as “Siamese Security Cable” or “Siamese Cable” and is simply 1 RG-59 cable and 1 18-2 cable (both explained below).
