SYSTEMS AND METHODS ASSOCIATED WITH DETECTION OF INDOOR GUNFIRE

摘要

Systems and methods are disclosed for reliably detecting gunfire in enclosed spaces having significant acoustic reverberation. Implementations are configured to quickly and reliably report the room or portion of a room where gunfire is located. Innovations herein may ensure low false alarm rate by thresholding, pattern recognition and/or detecting the muzzle optical flash. In some embodiments, a review center with trained personnel may evaluate the incident before reporting to local authorities. The indoor system can be incorporated into an outdoor gunshot location system to better protect a local area such as a campus or a transportation hub. Systems and methods herein may involve features and functionality associated with additional resources, such as intercoms, cellphones, and access control, to provide mitigation of harm in case of a shooting.

主权项

1. An indoor gunshot detection system comprising:
indoor sensors arranged to detect gunfire in a series of enclosed spaces having significant acoustic reverberation; wherein sensors are constructed with microphones designed to detect high amplitude impulses between about 120 dB to about 160 dB from nearby gunfire; one or more processing components and/or computer readable media configured to process potential gunshot data utilizing knowledge of particular sensor positions and designed to:
analyze impulses received by the indoor sensorsdetermine if the received impulses are gunfire, andpass alerts to at least one of local authorities, persons at risk, or a central alert facility; and at least one networking component constructed and arranged to transmit communications between the indoor acoustic sensors, the processing components and/or computer readable media, and computing devices that receive the alerts.
