Abstract

Between the camera (10), monitor (18) and energy source (20) is fitted a wired transmission path for transmitting video signals from camera to monitor, and supply voltage from source to camera. Between the camera and transmission path, and between the monitor, energy source and transmission path are fitted frequency switches (12,16). The transmission path is a symmetrical two-wire line (14). Each frequency switch contains symmetry members at output or input to the two-wire line.
