What Does ShotSpotter Do?
ShotSpotter helps police departments transform policing practices from reactive
to proactive by instantly notifying officers of gunfire location (gun crimes in
progress) with real-time data delivered to dispatch centers, patrol cars and even
smartphones. With real-time alerts, first responders receive precise gunfire
incident information, allowing informed decisions for faster emergency response
while also improving situation intelligence and increasing first responder safety.
ShotSpotter gunfire data also enables law enforcement agencies to improve
evidence collection, prosecution and overall police effectiveness.
➢ What Exactly is ShotSpotter?
The ShotSpotter technology is a series of audio sensors deployed high above the
street. When a gunshot goes off, and at least three sensors are triggered, the
sensors triangulate the sound. The exact time of arrival enables us to pinpoints
the exact GPS location of the gunfire. ShotSpotter trained acoustic experts
review and qualify all gunfire incidents and alert law enforcement immediately,
along with contextual information such as the number of shots fired, all within a
minute, and usually within 30 seconds, of the gunshot occurring.

What are the Benefits of ShotSpotter?
• Better ability to strategically and safely deploy into area and scene
• Locate possible suspect(s)
• Better probability to find critical evidence
• Locate victims and get EMS faster
• Better directed area canvass
• Helps identify problem areas (hotspots)
• Helps allocate proper resources (man power, cameras, lighting, etc.)
• Able to respond to shots fired calls more accurately and faster.
Sometimes before the first 911 call comes in, if one is even made.
• Able to conduct a better investigation with more resources and
information. (Time of Shooting, Number of Rounds, Audio, Enhanced
Report, Forensic Report, etc.)
➢ What has Miami Police done with ShotSpotter?
• We are doing next day knock on doors.
oCommanders assign uniformed personnel to visit each address
that had an alert go off and talk with the resident.
• We can now better plan ahead for celebratory gunfire by using last
years detected gunfire.
oWe do research weeks in advance to identify hot spot areas and
address where celebratory gunfire was detected last year.
• We can now address hot spot areas with more resources.
• We remind residents of the criminal consequences of celebratory
gunfire or test firing.
• We encourage media to report about the dangers of celebratory
gunfire and test firing.
