ROCHESTER, N.Y. (WHEC) — Twelve seconds after the radio call for shots fired Friday morning in an incident that led to a deadly shooting by police, ShotSpotter indicated gunfire.

News10NBC went in-depth on the ShotSpotter system.

Ron Teachman, Director of Public Safety Solutions, says computers and trained technicians distinguish gunshots from firecrackers and cars back-firing. 

News10NBC Chief Investigative Reporter Berkeley Brean: "How does the system work?"

Teachman: "The system works by setting up an array of acoustic sensors. (31) placed strategically in a city where they have experienced gunfire."

Recently in Chicago, groups criticized shot spotter for sending police to false calls. 

One led up to the recent shooting death of a 13-year-old boy.

Brean: "How accurate is the system?"

Teachman: "Well our customers tell us, in the aggregate, 97% accurate with a 0.5% false-positive rate."

ShotSpotter has been in Rochester since at least 2013. 

It was used in high-profile murder cases including the boys and girls club shooting and the murder of RPD Officer Darryl Pierson.
