1. An indoor gunshot detection system comprising:

  • indoor sensors arranged to detect gunfire in a series of enclosed spaces having significant acoustic reverberation;

    wherein the 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 non-transitory 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 one or more processing components and/or computer readable media, and computing devices that receive the alerts;

    wherein one or more of the sensors further include an IR detector to measure an optical flash of gunfire;

    wherein the one or more processing components and/or computer readable media is or are configured to compare shape or amplitude of the acoustic and IR impulses with known weapon or firework characteristics, such that classification of the impulses as a known weapon or firework can be made.
