The promise of Video Content Analysis or VCA technology for surveillance systems is to potentially gain back the active role of surveillance in security and alert the security personnel what, where and when something worth further investigation had happened.
VCA processes the video stream from each camera in real-time, detecting and tracking moving objects and annunciating alarms upon certain conditions that indicate prohibited or suspicious events. Automatic analysis of surveillance video content facilitates the logging of all video events, alarms, behaviors and interaction between moving objects in a database, providing a searchable storage that annotates and catalogues the video from each camera. With these automated capabilities, active surveillance promises faster situation assessment and faster dispatch and response, reducing property damage, losses, fines, liability, insurance premiums, and loss of life and injury.
