Baton Rouge Police Feature Mobile SENTRI for Crime Prevention

The Baton Rouge Police have followed in the footsteps of Memphis Police by employing the gunshot detection capabilities of SENTRI on a mobile platform that features the Safety Dynamics' gunshot box on a telescopic pole with lights.


Urban Crime Prevention

The new gunshot detection units will allow Baton Rouge police to transport the crime prevention functions of SENTRI to areas of immediate need and special community events. Crime rates at Safety Dynamics installations typically fall 14% with the presence of the new technology and a 35% drop in shootings and calls to 911 are realized within weeks. The Baton Rouge Police like the idea of moving SENTRI to various locations in the city that are seeing high rates of crime and for local community events to increase public safety through the SENTRI's unmatched detection and localization of gunshots in less than one second.


Memphis Police Unveil New Real-time Crime Center With SENTRI Gunshot Location Cameras

WMC-TV Action News 5 Coverage

Memphis Police unveiled their new, high-tech crime-fighting tool: The Real-Time Crime Center (RTCC) which features Safety Dynamics' biologically—based gunshot recognition for urban crime prevention. The RTCC includes a wall of 42 video monitors. Each monitor displays images from cameras spread all over the city. The system, monitored from 20 work stations, keeps tabs on everything from traffic to high-crime neighborhoods. When a gun is discharged, cameras with SENTRI gunshot detection slew to the origin of the gunshot and raise an alert to the RTCC, while recording digital video of the event.


Safety Dynamics Enters Final Stages of "Smart Fence" Development

Safety Dynamics has developed a perimeter security solution called "Smart Fence" under funding from the Office of Naval Research. The first Smart Fence prototype was demonstrated with great success to the U.S. Navy, the Naval Surface Warfare Center and the Transportation Security Administration at the Panama City Bay County Airport, FL in 2007. The Smart Fence brings together several sensors that all employ the Dynamic Synapse neural networks used in Safety Dynamics' gunshot recognition. The smart sensors serve as vehicle recognizers, footstep recognizers, and fence disturbance detectors for any chain-link fence perimeter in conjunction with camera nodes that slew-to-cue for intrusion events. The system is on track for Naval Facilities procurement and has recently been integrated with Virginia-based ObjectVideo's Intelligent Video camera system.

Safety Dynamics Completes LA Sheriff's Installation of Gunshot Detection System in Compton, CA

FOX News 11 Reports On SENTRI In L.A.

Los Angeles County Sheriff Lee Baca, Los Angeles Police Chief William Bratton and other police officials gathered at a news conference December 29 to announce the completion of work to install Safety Dynamics' SENTRI gunshot detection for urban crime prevention in the city of Compton. SENTRI units consisting of a camera and four microphones were scattered all over town a month ago, officials said.

"As soon as it hears shots fired, boom, the cameras turn," said sheriff's Lt. Scott Edson. The SENTRI unit is able to detect shots fired from within a quarter-mile radius and can even distinguish the type of rounds fired, said sheriff's Lt. David Telley. The unit employs neural networks, so it can listen for the temporal pattern of a gunshot and ignore similar sounds, like a bus backfire.

SENTRI; "Another Eye" for Law Enforcement

The Sheriff's Department, which provides law enforcement services in Compton, had tried similar technology called ShotSpotter, but Edson said the older equipment does not have cameras, only listening devices. "It's going to be like another eye for us, which will help us apprehend any suspects," Deputy Tony Bowie said of the new technology.

SENTRI is a stand-alone acoustic smart sensor which is capable of unambiguously recognizing and determining the direction and distance 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. SENTRI was part of the Chicago Police Department's "Operation Disruption," and currently protects areas in Charlotte, NC, Richmond, CA, and Tijuana, Mexico.


SENTRI To Keep Eye and Ears on Gunfire in Coastal Georgia

The Brunswick Police Department hopes to purchase SENTRI systems to help nab anyone who breaks the law by firing a gun in the city. "We hope to use the technology to identify people because most of the time when we get calls about gunfire, by the time officers get there, the suspects are gone," said Brunswick Chief of Police Edna Johnson. "These cameras would help us find and locate those who are actually discharging the firearms." The entire system of cameras and software – known as SENTRI – developed by Safety Dynamics has already taken a bite out of crime in cities like Los Angeles and Chicago.
