Abstract: Disclosed herein are wireless networks of gunshot detector arrays providing the firing location and trajectory of a gunshot, while being tolerant of clock drift among the network. Individual gunshot detectors may be battery-powered employing one or more microphones. Detectors may time-synchronize infrequently to conserve power. Detectors may communicate wirelessly to a central device that evaluates gunshot candidates, associates those candidates between detectors to individual gunshot events, and performs calculations to arrive at a solution for a gunshot direction and/or origin. Combinations of contemporaneous gunshot candidates may be reviewed for a best positional solution. The location of gunshot events may be displayed on an overhead image or map, to persons providing remedial actions, optionally with trajectories and potential zones of impact and damaged assets.
