The Chicago Police Department is expanding the use of a gunshot detection system and surveillance cameras in areas of the city that are dealing with high rates of gun violence.
Known by the brand name ShotSpotter, the sensors system uses technology that listens for the sound of a gunshot then triangulates its exact location.
After being used in other cities, the system was launched in Chicago in 2012 in two 1.5-square-mile areas of the same police districts.
Under the new expansion, the ShotSpotter system and crime cameras will be in police districts on the city's Englewood neighborhood on the South Side and Harrison on the West Side. Chicago police Superintendent Eddie Johnson said the 13.5-square-mile area is where the majority of gun-related violence is taking place.
Johnson said the technology "allows us to police smarter and be more proactive than reactive when it comes to responding to and investigating shooting incidents across the districts."
