ai_defender

AI Defender consists of a series of devices located throughout an institution (university, public school, etc.) that have been trained to recognize the sound of gunfire through a machine learning algorithm. Upon detection of gunfire, a central server is notified by the device, which tracks location and timing data (e.g.: shots fired in Room 230, 37 seconds ago; shots fired in Hallway 3 West, 8 seconds ago, ...). Users of a mobile app are informed of the incident and provided with the latest data.
