System Overview

Closed Circuit Television Systems are locally managed video systems designed to monitor key areas of a facility.  These systems can be overt (in the open) or covert (hidden). 

The basic components of a closed circuit television system consists of cameras, lens, mounts, and head end control equipment (monitor, time lapse recorder, switcher, multiplexer, matrix switcher).

The systems can be either color or monochrome (black & white), and can consist of fixed cameras, pan tilt zoom cameras or a combination of both. 

 

The head end equipment typically consists of a monitor, recorder, and video multiplexer.  The video multiplexer allows for multiple video signals to be recorded on a single VCR.    A library of tapes is maintained and reviewed in the event of an incident. 

These systems are typically used for monitoring key entry / exit points into a facility, parking lot areas, shipping and receiving areas, engineering labs, production areas and other critical areas through out a facility. 

Video systems are often used in conjunction with access control systems.  They are helpful in detecting tailgating (following an authorized user through an entry point).
