The SENTRI Solution: A New Age In Law Enforcement


Safety Dynamics specializes in the use of smart sensors for threat recognition and localization. Safety Dynamics is currently selling and supporting a system for law enforcement called SENTRI (Sensor Enabled Neural Threat Recognition and Identification). The system is a breakthrough technology that recognizes gunshots and explosions and sends range and bearing details to cameras which can then locate the source of the event. The patented Dynamic Synapse Neural Network (DSNN) technology developed by the Laboratory for Neural Dynamics at the University of Southern California is at the core of the acoustic recognition capability and 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. Whether standing alone in a choke-point or working with mulitple units to cover a large area, SENTRI is part of a network of surveillance cameras which listen for gunshots and provide police with the ability to use audio and video for the identification of crimes in progress.

SENTRI Smart Fence: Airport and Facility Perimeter Protection


Safety Dynamics is currently developing a perimeter security system called Smart Fence under SBIR Phase III funding from the Office of Naval Research. Safety Dynamics demonstrated first–generation prototypes to the Navy, Naval Surface Warfare Center and TSA. A wireless, low-power system is now in development for use in the protection of small- and medium-sized airports in the United States. The Smart Fence specifically detects the approach of vehicles, footsteps, gunshot and fence disturbence including an integration with ObjectVideo's Intelligent Video cameras to create a complete perimeter defense solution.
