Chicago police are using a new technology that can listen for gunshots and help the responding officers pinpoint where they were fired. The technology, called ShotSpotter, relies on an acoustics-based, GPS-equipped system to feed police the location of a gunshot. "Not only do we learn where the shots are being fired but now those officers can actually turn cameras on the location, get actionable intelligence that they can feed to the officers in the field as they're approaching," Police Superintendent Garry McCarthy explained Thursday via an NBC Chicago broadcast.
The newer systems that are supposed to have improved accuracy come just a few years after the city originally questioned the reliability of the technology, which neighboring Gary, Ind., has been using with good results since 2005. Police officials gave the ShotSpotter technology used in Gary a chance before quietly pulling the initiative. The city tried a different system in 2004 in which microphones and cameras were mounted on poles. NBC Chicago reports the newer system comes with a price tag of roughly $100,000 for every 1.5 square miles its used. The technology is currently used in three square miles.
