SENTRI System Recognizes People

Safety Dynamics is creating a system to separate the gentle susurration of the waves from the sound of an invading amphibian army. Designed to pick out unnatural noises – glass breaking, chain link rattling, the odd, inopportune cough – SENTRI can tell the difference between natural, repetitive sounds and unnatural breaking and entry. Planned chemical sensors will even allow it to tell the difference between shots fired and a truck backfiring.

SENTRI, designed for the U.S. Office of Naval Research, is now being used by two police departments and can call in for back up or aim cameras at a certain location. Up next is a mobile version. Maybe something that shocks you when a raccoon is rustling in your campsite trash? (Via Gizmodo)
