Back to Basics: What Are CCTV Cameras?
CCTV is small for closed circuit television. While most human beings reckon that it refers to cameras, it really refers to the path the signals are transmitted from one medium to another. When we affirm "closed circuit" we mean to affirm that the installation consists of circuit components directly connected in such a path that only the human beings within the circuit can view it. CCTV camera systems are very different from ordinary TV systems since their signals can only be viewed by a select number of human beings.
