As in many other cities in the U.S. like in Detroit or Saginaw, the city authorities of Hartford (Connecticut) are planning to install audio sensors in high-crime neighborhoods to detect gunshots and determine location.

The City´s Mayor Pedro Segarra announced yesterday the implementation of the ShotSpotter program.

The city will spend $150,000 on the sensors, which allegedly can differentiate between gunshots, firecrackers, and cars backfiring, and then notify police over a computer network when a shooting has occurred.

The computer can report where the shot was fired from, by using tringulation (similar system to the GPS) and by calculating the amount of time it takes the sound to reach the sensors.

These sensors has been also allegedly used in urban areas in military conflicts abroad the U.S.

The technology was first implemented in Redwood City, Calif., in 1996. The ShotSpotter system,  is composed of a series of acoustic sensors mounted on telephone poles, building rooftops, and other inconspicuous locations in a predetermined area. The pizza-box-sized sensors employ GPS technology to triangulate a gunshot’s location, using a formula based on the speed of sound to calculate the exact location from which a noise above a certain decibel level emanates. The time between when a gun is fired in a ShotSpotter zone and when police receive detailed information about its location on their in-car laptops is measured in seconds — a span that could mean the difference between life and death.

There is another great value with the Shotspotter Program, is a strong deterrence force against crime.
