"High-tech gadgets that can trace gunfire to its source are being installed around the city with the hope of getting police officers to crime scenes more quickly. The ShotSpotter Location System will use acoustic sound sensors mounted on sides and rooftops of buildings to feed data to a computer if a shot is fired. The computer will then pinpoint the location of the gunfire by measuring the distance of the shot from each sensor. Rochester will join a handful of cities already using the technology developed by Mountain View, Calif.-based ShotSpotter Inc., including Charleston, where officers have said it has helped them determine the location of shootings in neighborhoods where people have been unwilling to get involved."
