Shotspotter lets police pinpoint where gun was fired
. In Milwaukee, for example, if you fire a gun in some neighborhoods you might find yourself surrounded by police in just a few minutes.Thatís thanks to a technology deployed in Milwaukee and 74 other cities both in the United States and other countries created by ShotSpotter. The company, which was founded in 1995, uses an array of acoustic sensors deployed in a neighborhood that listen for one thing: the sound of gunfire. The sensors are paired with software that can analyze the sounds in real time, triangulating and pinpointing the location of each round fired down to the latitude and longitude. The software also filters out non-gunfire sounds that might have triggered the sensors, and the sound is also sent to trained officers who act to confirm that itís gunfire before an alert is sent to officers on patrol.In the first quarter of 2013, the company told me, their system detected 7,584 separate gunfire incidents in 30 cities they pulled data from. In those incidents, 26,617 rounds were fired Ė about 3.5 rounds per incident. One of those incidents saw 63 rounds fired. 63% of gunfire, they found, takes place between 8pm and 4am (local time) with 54% of that gunfire happening on Friday, Saturday and Sunday.
