SENTRi GUNSHOT DETECTION SYSTEM

by Safety Dynamics

 

ACOUSTIC TEMPORAL PATTERN RECOGNITION SYSTEM

FOR GUNSHOT AND EXPLOSIVE SOUND DETECTION

The SENTRi (Sensor Enabled Neural Threat Recognition and Identification) developed by Safety Dynamics emerged as a result of years of Department of Defense grant funding to the Department of Biomedical Engineering, University of Southern California for the development of the Dynamic Synapse Neural Network (DSNN).


The SENTRi utilizes a suite of algorithms including the DSNN technology which is based on neurobiological principles of brain signal processing, and allows, like the human brain, accurate temporal pattern recognition of acoustic signals even in the presence of high noise.  The SENTRi provides precise temporal pattern/sound recognition and localization of urban gunshots in less than one second from sound arriving at the sensor.

SENTRi (Sensor Enabled Neural Threat Recognition and Identification) is a stand-alone acoustic smart sensor which is capable of recognizing and determining the direction of targeted sound signatures which can work in concert with other modes of sensor detection, such as intelligent video, to validate and isolate the source of the sound. In the case of law enforcement, SENTRi is trained to listen for gunshots.

With this technology in place, the benefits to law enforcement are many: quicker reaction times, accurate location of the origin of the threat, and the active discouragement of crime by the mere presence of SENTRi units.
