Woah, this might change the face of crime as we know it. of course, for the benefit of the community! This technology detects the sound of a gunshot and calls for aid accordingly. It also can pinpoint the shooter's location within 10 feet.

It involves placing a series of sensors 1,500 feet apart, then linking them with surveillance cameras throughout the city. The sensors go on existing structures, such as buildings and telephone poles.
The ShotSpotter system is only triggered by gunfire and it can discern the type of weapon (rifle, shotgun or handgun) being used. The software in the sensors also commands the surveillance cameras to rotate and focus on the spot where the shot was fired.
The sensors are so sophisticated that they can trace the path and direction of drive-by shootings.
