Title: SYSTEM AND METHOD FOR IDENTIFYING AND LOCATING SENSED EVENTS
Abstract:
Method and system for detecting multiple alarms triggered by the same event and suppressing the duplicate detections, reducing false alarm rate. The first sensor to be activated is identified via a timestamp associated to the activation, then it is identified whether the other sensors have been activated by the same event. In particular a plurality of microphones is deployed in separate rooms to detect gunshots from firearms in a indoor setting.
