  • Patent number: 8184154
    Abstract: A surveillance method periodically detects an image of the area, identifies and tracks each moving object in a succession of the detected images, detects radio frequency emissions from the area and correlates an identified object with a detected radio frequency emission. The method detects events in the tracking of the moving object. The method stores corresponding data optionally including image data in non-volatile memory upon detection of a combination of an event and a corresponding radio frequency emission. The method triggers an alarm such as an audible alarm, a visual alarm, an email, a short text message or a telephone call detection of a combination of an event and a corresponding radio frequency emission.
