#Do you report the sound of a gunshot to the police software#

Lahr modified the software typically used for locating earthquakes and recorded the data at a higher sample rate than is used for regional seismology. A network consisting of one wired and four radio-telemetered microphones was established, with his home in eastern Menlo Park becoming the command center. Lahr decided to go ahead with his plans to demonstrate the feasibility of locating the gunshots, relying on his background in the earthquake location techniques and monitoring in Alaska. One key attendee was Robert Showen, a Stanford Research Institute employee and expert in acoustics. At that time there were no solutions to tracking gunshots, only a desire to do so. The police chief arranged a meeting with local inventors and entrepreneurs who had expressed an interest in the problem. Others had also approached the Menlo Park police department suggesting ways to help the police by means of gunshot location systems. Lahr, a PhD seismologist at the nearby United States Geological Survey, approached the Menlo Park police department to ask if they would be interested in applying seismological techniques to locate gunshots. The Menlo Park police department was often called upon to investigate when residents reported gunshots however there was no way to determine their source from scattered 911 calls. During 1992 there were 42 homicides in East Palo Alto, which resulted in East Palo Alto becoming the murder capital of the United States. In the early 1990s, the areas of East Palo Alto and eastern Menlo Park, California, were besieged with crime.

The DGA & Section Technique de l’Armée de Terre (STAT), the French Army’s engineering section

In 1990, a unique algorithm was used as a starting point : Metravib defence, working with Délégation Générale pour l’Armement (DGA) – the French defence procurement agency – studied the acoustic signature of submarines. Some indoor gunfire detection systems utilize detailed floor plans with detector location overlay to show shooter locations on an app or web based interface.ĭetermination of the origin of gunfire by sound was conceived before World War I where it was first used operationally ( see: Artillery sound ranging). Systems used in urban settings integrate a geographic information system so the display includes a map and address location of each incident. In general categories, there are environmental packaged systems for primarily outdoor use (both military and civilian/urban) which are high cost and then also lower cost consumer/industrial packaged systems for primarily indoor use. A user-interface that displays gunfire alerts.An array of microphones or sensors ( accelerometers, infrared detectors, etc) either co-located or geographically dispersed.Most systems possess three main components:

These systems are used by law enforcement, security, military, government offices, schools and businesses to identify the source and, in some cases, the direction of gunfire and/or the type of weapon fired. A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, vibration, optical, or potentially other types of sensors, as well as a combination of such sensors.
