Abstract: Techniques for low power gunshot sensor testing are disclosed. An acoustic generator and an infrared generator are disposed in a housing. The housing encompasses the acoustic generator and the infrared generator. The housing covers the gunshot sensor. The acoustic generator and the infrared generator are used for testing a gunshot sensor. The infrared generator and the acoustic generator are coupled to an activation circuit. A switch is coupled to the acoustic generator and the infrared generator. The switch provides activation control of the acoustic generator and the infrared generator. The infrared generator includes a light source operating in the near-infrared (NIR) band. The light source operating in the NIR band provides testing for a gunshot muzzle flash sensor. The infrared generator includes a light source operating in the mid-infrared (MIR) band. The light source operating in the MIR band provides testing for a passive infrared (PIR) sensor.

Abstract: Techniques for low power gunshot detection are disclosed. Infrared information is collected using a gunshot sensor device. The infrared information is collected using mid-infrared band sensing to provide motion detection. Additional infrared information is buffered using the gunshot sensor device. The additional infrared information is collected using near-infrared band sensing. The buffering is enabled by the motion detection. Acoustic information is collected using the gunshot sensor device. The collecting acoustic information is enabled by the motion detection. A gunshot is detected using the gunshot sensor device. The detecting is based on the additional infrared information and the acoustic information. The detecting includes monitoring the acoustic information to identify a high-intensity gunshot sound and correlating the high-intensity gunshot sound to the infrared information that was buffered. The gunshot sensor device uses cable-free communication to a network and notifies the network of a possible gunshot occurrence.

Abstract: Techniques for gunshot sensor testing are disclosed. An acoustic generator and infrared generator are disposed in a housing. Soundproofing insulation is distributed around and/or within the housing to provide sound deadening which minimizes disturbance to building occupants during testing. The housing is placed in proximity to a gunshot sensor. A trigger device enables multiple modes of triggering both the acoustic generator and infrared generator. The generators stimulate corresponding components of a gunshot sensor. Input from the gunshot sensor components is evaluated to determine an operating condition of the gunshot sensor. The gunshot sensor verifies its operation by communicating with a server. The server further tests mass communication channels by issuing a test message. The test results indicative of the condition of the gunshot sensor are sent to a mobile device for an operator to review.

Abstract: Techniques for gunshot detection 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 acoustic sensor and an infrared sensor. A firearm typically emits energy within the infrared spectrum when fired. This energy is detected by the infrared sensor. A firearm also typically emits an acoustic pressure wave when fired. The acoustic sensor detects the acoustic pressure wave. A strobe from a fire alarm occurring near in time to the gunshot can cause false gunshot detection. The infrared sensor information and the acoustic sensor information are analyzed to determine that a gunshot has occurred. The gunshot determination takes place independently of the location of the gunshot sensor. The strobe occurrence is evaluated to provide gunshot false alert detection. Reverberations are not used in the determination of a gunshot false alert.

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.

Abstract: Techniques for cable-free indoor gunshot detection are disclosed. Acoustic information is collected within an indoor environment using a gunshot sensor device which uses cable-free communication to a network. The gunshot sensor device is powered by a battery. Infrared information from the muzzle flash of a firearm is collected using the gunshot sensor device. The infrared information is buffered within the gunshot sensor device. The gunshot sensor device is used to monitor the acoustic information and identify a high-intensity gunshot sound. The gunshot sensor device is used to match the high-intensity gunshot sound to the buffered infrared information. The matching includes making a correspondence between the gunshot sound and an infrared event that occurred in time before the gunshot sound. The gunshot sensor device is used to notify the network of a possible gunshot occurrence, based on an analysis of the high-intensity gunshot sound and the infrared event that was matched.

Abstract: Gunshot detection within an indoor environment is performed with video analytics. One or more position-independent gunshot sensors are deployed. Infrared and acoustic information is collected within an indoor environment for indoor gunshot detection with video analytics. The infrared information and the acoustic information are analyzed to determine a gunshot occurrence. Video analytics for tracking a suspected shooter of the gunshot is performed, based on the gunshot occurrence, using video that is collected. A person of interest is tagged, as a portion of the video analytics, for the purpose of tracking the person of interest. Video collection from one or more video streams is engaged, based on the detection of the gunshot. The video analytics uses image classifiers. The image classifiers are used to identify a gun type. The suspected shooter is identified based on the video analytics. An audio microphone is activated based on the detecting of the gunshot.
