ST. LOUIS, Mo. — A system that can recognize the sound of gunfire and identify its location will be installed in St. Louis with money from a federal grant, the police department announced Wednesday.
The "urban gunshot detection monitoring system" compares sounds reaching microphones at various locations to triangulate the exact location of a shot within seconds. The mikes have a range of about one mile each.
Police said it should provide quicker police response and result in more weapons arrests and confiscations.
