This surveillance software from Prescient Systems records images only when triggered by motion. It provides time-stamped video files of events as they occur, without recording the inactivity between events. Features include the ability to mask out unwanted movements, to play an audio file when someone enters your office, and to send a page when motion has been detected. Gotcha even has a timer with which to schedule monitoring.

Note: There is a 30-day trial period and a 30-minute time lock each time you run the unregistered version.
