Vision based system and method for detecting a breach of security in a monitored area. One or more sequences of events are stored in the system. Each sequence of events includes a different combination of events and an order in which the events have occurred. An action is associated with each sequence of events such as triggering an alarm, generating an audible sound, calling 911 etc. when the events detected by the system match a given sequence the action associated with that sequence is performed. The system receives an image stream of the area and detects the events occurring in the images including the detection of a human body, its size and location within the monitored area. The system may be activated at all time without requiring people in the monitored area to change their normal behavior. |
