Gunfire detector

Safe Zone says its Safe Zone
Gunfire Detection System is an active shooter security breakthrough. President
Mike Anderson said, “The Safe Zone system responds within ten seconds to an
active shooter situation, analyzing the on-the-ground situation and
automatically communicating with all key personnel, from first responders to
school administrators to parents and management.“

According to Anderson,
statistics show it takes an average of five minutes for police to be notified of
an active shooter situation by someone on scene, due to the chaos and immediate
danger presented.

Priced at $149 per unit, the
Safe Zone Gunfire Detector combines the latest infrared and sound detection
technologies with immediate cloud-based data analysis that can analyze more
than 3,000 data points of each loud noise that exceeds ambient levels by a
certain threshold.

Utilizing the data from
multiple detectors simultaneously, the system determines the location of shots
fired, the number of shots, and the type and caliber of gun being used. Within
ten seconds of the trigger pull, an alert is sent to Public Safety Access
Points in the appropriate dispatch center, giving local 911 dispatchers all the
critical information right on their computer. This can greatly reduce the time
needed to locate and engage shooters, as experts say officers arriving on scene
would normally take up to 12 minutes to obtain usable information from shocked,
and often conflicting, witnesses. 

The Safe Zone Gunfire
Detector is a small (less than 3” x 3”) triangular unit that mounts in a
ceiling corner and provides gunfire detection for an area of up to 9,000 ft3.
Safe Zone utilizes the latest WiFi communication and cloud-based machine
learning technologies to send and analyze data that returns usable information
to local law enforcement and on-site administrators in less than 10 seconds.
Unlike many other gunfire detection solutions, Safe Zone can be connected to
third-party alarm, surveillance, door lock and mass notification systems.

Each detector monitors
ambient noise and infrared level, with a full second of data recorded around
any instance of a sudden increase in noise or light level. If an Infrared flash
or sound more than 10 dB louder than ambient noise is detected, all detectors
in range send the captured acoustic and IR signals to Safe Zone’s cloud-based
machine learning system where they are compared against a database of thousands
of signatures of known firearms and other non-firearm disturbances. The system
analyzes more than 3000 data points in each record. False alarms like car
backfires, firecrackers or balloons popping are filtered out through their
distinct acoustic signatures.
