Product Summary

Sound & Optics Systems has developed a unique security platform that provides integrated real-time solutions for a variety of criminal and threat challenges. The Sentri II system is a neural stimuli blended technology product that is able to “hear” a sound, recognize it, and focus a camera on the sound source in less than a second. Within seconds, a command center or local patrol vehicle is able view the incident in progress, as well as zoom in on possible suspects or other activity.

This unique leading edge sound recognition logic combined with a camera and other optional detection devices, such as seismic or vapor sensors, creates an intelligent remote surveillance system that will increase patrol effectiveness, decrease patrol unit risks upon scene arrival while also providing prosecution evidence 24 hours a day, 7 days a week, in any weather or location.


Potential Applications

The Sentri II system can provide significant benefits to many potential application areas such as the following:

  • Law Enforcement
  • First Responders
  • Border Patrol
  • Sea Port
  • Parking Facilities
  • Educational Facilities
  • Private Security
  • Forest Service
  • Commercial

For each of these application areas, the Sentri II system:

  • Provides real-time, pre-determined threat recognition for specified enforcement and/or protection areas
  • Extends capacity of current force by providing ‘on-site’ monitoring, reporting and recording of designated events such as gunshot or seismic occurrence
  • Enhances responder effectiveness by providing on-going real-time on-scene information
  • Serves as key witness with ‘photographic memory’ of criminal events and suspects

Product Description

The basic Sentri II System is an enclosed weatherproof platform that contains acoustical recognition detection capabilities, a high performance security camera, wired or wireless communications, an alert system, operating software and other optional equipment. When a pre-determined sound (e.g. gunshot) is recognized, the camera automatically moves/zooms to the sound source. It then sends an alert, other pertinent information and video images to the command center or control room while capturing and displaying information about the incident in real-time.

This provides law enforcement or other personnel critical and timely information, assisting them in making rapid decisions and enabling them to quickly deploy additional officers and activate public safety protocols.

Sentri II units can be mounted, in networked groups or as single units, to existing light or telephone poles in a problem locations such as a high-incident neighborhood, boat docks and piers, potential drug trafficking and border crossing trails or singly in targeted areas such as warehouses, research labs and high-traffic train crossings. The units are easily moved from one location to another.
