A Gunshot Location System is a system which identifies the location of a gunshot or other weapons-fire using acoustic, optical or potentially other types of Sensors . These systems are used by law enforcement, homeland security, military and commercial customers to identify the source and, in some cases, the direction of gunfire and/or the type of weapon fired. The efficacy of these systems is generally reduced by flash suppressors and silencers, and most of them do not detect weapons fired indoors or under ground. TYPES OF GUNSHOT LOCATION SYSTEMS Gunshot Location Systems generally require one or more ''sensing technologies'' to detect either the fact that a weapon has been fired or to detect the projectile fired by the weapon. To date, only sound and visual or infrared light have successfully been used as sensing technologies. Acoustic Gunshot Location Systems Acoustic systems use the Bullet Bow Shockwave (the sound either of the projectile or bullet as it passes through the air), the sound of the muzzle blast of the weapon when it fires the projectile, or a combination of both. Because sound waves can bend (refract) as they travel through the air, and because sound can travel as far as a mile or more away from its origin, it is possible for acoustic gunshot location systems to detect gunfire events at long ranges, and do not require that they be within line of sight of the weapon being fired. Acoustic systems can generally be defeated by "silencers," more technically known as Suppressor s. Optical Gunshot Location Systems Optical or electro-optical systems detect either the muzzle flash of a bullet being fired or the heat caused by the friction of the bullet as it moves through the air. Such systems usually require that they have a clear line of sight to the weapon being fired or the projectile while it is in motion. Such systems can generally be defeated by specialized Flash Suppressor s. EXTERNAL LINKS
