Abstract
A system and method for detecting, identifying, and fixing the location of the source of an acoustic event. The inventive system includes: a plurality of sensors dispersed at somewhat regular intervals throughout a monitored area; a communication network adapted to deliver information from the sensors to a host processor; and a process within the host processor for determining, from the absolute times of arrival of an event at two or more sensors, a position of the source of the event. Acoustic events are detected and analyzed at each sensor so that the sensor transmits over the network: an identifier for the sensor; an identifier for the type of event; and a precise absolute time of arrival of the event at the sensor. In a preferred embodiment, the system also identifies the type of weapon firing a gunshot.

15. A method of directing a camera towards, a gunshot event, the method comprising:
-
networking at least three sensors across an area to be monitored, wherein each of the at least three sensors is configured to detect the gunshot event, and wherein the location of each of the at least three sensors is known; performing time of arrival processing of the gunshot event at each of the at least three sensors; determining an approximate location of a source of the gunshot event as a function of arrival time and sensor location data; and performing processing associated with generating instructions to direct a movable camera towards the approximate location.
