I was recenly reading an issue of Wired and learned about shot spotter technology. I have actually heard about it before because it has been implemented where I live(Rochester, NY). When a gun is discharged the technology used sound sensors and triangulation to find ut where the shot came from and even the type of gun. Authorities are notified and dispatched to the location. Shotspotter is borrowed from army technology, it seems like a trend that once the army has used it for a while it goes into civilian production.
