VCRS

It relies on specialized equipment such as cameras, cables, video recorders and monitors. For example, a video camera outputs a video signal through a dedicated coaxial cable. The cable is connected to special analog video equipment, such as video image splitter, matrix, switcher, cassette recorder (VCR) and video monitor. There are a number of limitations in the simulation of CCTV:



The limited monitoring capability supports only local monitoring and is limited by the length of the analog video cable transmission and the cable amplifier.



Systems with limited scalability are usually limited by the input capacity of video splitter, matrix and switcher.
