A danger monitoring system is disclosed. A danger monitoring device comprises a microphone configured to continuously digitize environmental sound, a first memory, a first processor configured to determine whether a stored interval meets a threshold criteria for a dangerous event, and a first network interface configured to send a danger observation data to a server. The danger monitoring server comprises a second memory, a second processor configured to verify the dangerous event digitized by the danger monitoring device and determine an event location of the verified dangerous event, and a second network interface configured to send a danger alert. A danger mitigation device comprises a third network interface configured to receive the danger alert, a GPS receiver, a screen, a third memory comprising map data, and a third processor configured to render a map indicating at least a current location of the danger mitigation device, and the event location.

A system and method for finding the proximate location of an indoor active shooter including: a plurality of acoustic sensors for receiving acoustic information from a monitored area, the sensors being dispersed in the monitored area, and each sensor having a processor for discriminating gunshot candidates from other sounds; and a host processor/server for receiving the gunshot candidates from the sensor and provide further processing to determine if the gunshot candidate is a gunshot. The server may use the first sensor to report as the proximate location of the shooter. As nearby sensors report the same incident, the server may refine the proximate location to within a few feet of the actual location of the shooter. The host processor includes a program or instructions to determine exit routes from the detected shooter and to activate a warning system which directs people away. The warning system includes a plurality of signaling lights capable of producing light in a plurality of selectable colors such that the host processor commands the lights to signal colors which warn people of the direction of the proximate location and other colors which direct people away from the proximate location.

An event detection unit (EDU) for detecting an explosive event is provided. The EDU includes different types of sensors for measuring characteristics of an explosive event. The EDU includes an event notification component. The EDU also includes a processor that receives a measurement from the sensors and generates a combined non-event probability and a combined event probability based on that measurement that indicates a likelihood that an explosive event has not occurred or has occurred. The processor determines whether an explosive event has occurred based on the non-event probabilities and event probabilities. When an explosive event has been determined to occur, the processor directs the event notification component to output a notification that an explosive event has occurred.

A firearm discharge detection method includes: programming a gunfire detector to report audio sensor data that comprises acoustic data falling outside of an expected sound level; receiving the audio sensor data; comparing the audio sensor data to stored gunshot signatures to identify possible gunfire; reporting the possible gunfire.
