City residents are advised to not be alarmed by gunfire in the area of Seventh and Swift streets as the Troy Police Department will be testing its newly-acquired ShotSpotter system with live fire from 10 p.m. to midnight near the Department of Public Works.

The city acquired the $250,000 piece of technology, which is able to pinpoint the location of gunfire within five feet of where it was discharged and even distinguish between different calibers of weapons, back in November.

Police plan to use the system in various areas around the city in an effort to stop gun violence, quickly apprehend criminals, and defend the use of their firearms in court if someday necessary.
