Sandra Turner-Handy Detroit, MI | Resident
We can't have a violent crime violence reduction strategy if we don't know about 80% of the gunfire...To me 2 lives saved, 47 guns recovered and a police response to 80% more of the crime is pretty exceptional.

[ShotSpotter] is saving us time, making us more efficient and allowing us to solve crimes, and to link crimes … the linking of the shell casings allows us to see trends, see pictures and to realize if we’re having a spike in a certain group, and be able to address those needs better.

ShotSpotter Respond Frequently Asked Questions

Police rely on the community to call 911 if gunshots are fired, but only 20% of incidents are ever reported on average. This creates a situation where police departments have a large data gap that makes it difficult to be able to effectively “serve and protect” when it comes to gun violence. ShotSpotter fills the gap with a network of acoustic sensors that can detect, locate and alert police to nearly all gunshot incidents. The system is in operation in more than 135 cities and is used by police to: 1) be able to respond to a higher percentage of gunfire incidents; 2) improve response times to crime scenes to better aid victims and find witnesses; and 3) help police locate key evidence to identify and prosecute suspects.

ShotSpotter uses an array of acoustic sensors that are connected wirelessly to ShotSpotter’s centralized, cloud-based application to reliably detect and accurately locate gunshots using triangulation. Each acoustic sensor captures the precise time and audio associated with impulsive sounds that may represent gunfire. This data is used to locate the incident and is then filtered by sophisticated machine algorithms to classify the event as a potential gunshot. Acoustic experts, who are located and staffed in ShotSpotter’s 24×7 Incident Review Center, ensure and confirm that the events are indeed gunfire. They can append the alert with other critical intelligence such as whether a fully automatic weapon was fired or whether there are multiple shooters. This entire process takes less than 60 seconds from the time of the shooting to the digital alert popping onto a screen of a computer in the 911 Call Center or on a patrol officer’s smartphone or mobile laptop.

ShotSpotter is used in more than 135 cities and is highly regarded by law enforcement as a critical component of gun violence prevention and reduction strategies. ShotSpotter protects a wide range of city types and sizes ranging from urban metropolitan cities such as Chicago and New York City; to medium-sized cities such as Boston, Denver, and Oakland; and small cities with populations less than 50,000 such as Richmond, CA and Pleasantville, NJ. More about ShotSpotter cities can be found here.

Gunshot detection by itself is not a panacea for gun violence, but if used as part of a comprehensive gun crime response strategy, it can contribute to a reduction in response times, help to save the lives of GSWs, and improve evidence collection rates. Please visit Results for more details.

The ShotSpotter system is highly accurate at detecting outdoor gunshots. From 2019-2021 the system had a 97% aggregate accuracy rate across all of our customers including a very small false positive rate of less than 0.5% of all reported gunfire incidents.
