CCTV Systems

These systems are used to monitor, record and affect activity inside or out. Today's technology now provides high quality video in just about any type of lighting or environmental conditions. Cameras can be covert (to thwart a sophisticated thief for example) or highly visible (to serve as a deterrent to undesirable personnel activity). Digital video recorders (DVR's) are now a common retrofit to solve the problems of tape-based systems — video quality degradation and tape change-out. Using DVR's, personnel can review video from a moment ago without interrupting recording in progress. Multiple reviews can even take place simultaneously from the different locations, on or off site. Tape swap-out is eliminated, and back-up recordings and archiving can be automated where required.

Video monitoring can be also triggered by alarms or motion detectors to eliminate the consumption of storage space recording inactivity. Trigger application also simplifies the review of video activity. Advanced technologies provide for facial recognition, subject tracking, and still capture. Stills can be printed, posted to public displays ("have you seen this person?") and transmitted wirelessly to roving security personnel with hand-held devices.
