Video Recording Equipment|
(Chapter 2 Video Surveillance, Continued)
It may not be necessary to have all the features of a time-lapse recorder. Time lapse was developed to give a continuous flow of recorded information that could span long periods of time in a very small, storable format. If a school is able to interface its intrusion detection or other type of alarm system with their CCTV system (which is viewing the area where an alarm is occurring), an event recorder is capable of turning itself on to record that event almost instantaneously. Not only does this feature allow a tape to be used for very long periods of time, as no recording is being done during uneventful times, but event recorders are generally cheaper than time-lapse recorders.
