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.
