Closed circuit television

Closed circuit television is used with guards to enhance their surveillance ability and to record events. Recording can be either a set of stills taken at a determined interval (take a picture every 5-30 seconds) or constant video recorded to a tape system or digitally to a hard drive. For example, a CCTV system that monitors a low traffic area could take a picture every 30 seconds but increase it to every 2 seconds when it detects activity. CCTV is a great way for guards to monitor a larger area with few guards.
