Abstract
Techniques for gunshot analysis in an indoor environment are disclosed. A gunshot sensor is placed in the indoor environment. The gunshot sensor includes multiple individual sensors, including, but not limited to, an infrared sensor and an acoustic sensor. A firearm typically emits energy within the infrared spectrum, which is detected by the infrared sensor. A firearm typically further emits an acoustic pressure wave, which is detected by acoustic sensor. The gunshot detector can differentiate between a gunshot and a strobe from a fire alarm, based on information from the infrared sensor and acoustic sensors. The infrared sensor information and the acoustic sensor information are analyzed to determine that a gunshot has occurred in a timeframe between strobe events. The gunshot determination takes place independently of the location of the gunshot sensor. Reverberations and reflections add cumulatively to the collected acoustic and infrared information.
