Sound Surveillance For The Spots That Cameras Can't Quite Get
from the they're-listening dept
There seems to be tons of innovation these days in the surveillance industry. New technologies are springing up that allow law enforcement to detect the presence of microscopic (but incriminating) objects, like drug residue, and in the future, surveillance cameras may be able to automatically recognize when suspicious activity is going on. But any technology that relies on a line of sight will fail to detect someone lurking behind a building, or in a shadow. That’s where ShotSpotter comes in. Using a network of sensors, the technology instantly identifies the exact location of a gunshot and relays it to police. So where it’s hard to capture every square foot of an area with cameras, sound can fill the gap. Of course, false positives will probably be a problem, unless it can be certain of the difference between the sound of a gun, and other loud noises that are often heard in a city. Update: Turns out this is fairly old news. We had stories about it nearly four years ago.
