ShotMonitor offers low cost open source gunshot detection and localization for neighborhoods using off the shelf security cameras. It combines their microphones into an acoustic array, uses short phone-played sounds to synchronize their clocks, and estimates where sound events originate on a satellite map. Meta’s AI models add audio descriptions and plain-language explanations, connecting each event to its supporting evidence and uncertainty as well as deeper analysis.
