What are shot detection systems and why is there demand for these systems?
Shot or shooter detection systems were first developed and used by the military to detect incoming fire and assist in determining where this incoming fire originated. These systems were then developed and adapted to be used by law enforcement across the country to enhance their ability to detect, locate and respond to gunfire in a more effective manner, and in a much shorter timeframe. In most cases, deployment of these systems in certain areas of a city rely on the acoustical detection of gunshots only due to distances, line of site obstructions, and potential other issues. However, setting up several detection sensors in an area not only detects the gunshots, but allows the system to triangulate the shot’s origin by measuring and comparing the amount of time or delay of the detection across several detection units in the area.
These systems were further developed to be used for indoor applications, to include schools, colleges, or any commercial or industrial environment where concerns may potentially exist to address active shooter events. The shot detection systems for indoor environments are typically developed to cover shorter distances, and depend on additional technologies to deal with walls, hallways, gyms, warehouse spaces, and other room or area designs that would cause echoes or other detection issues. These additional technologies would include sensors that would detect specific acoustics and infrared flash detection, or other sensors that sense the gunshot due to the energy level and wave form of the shot. The accuracy of these different systems, to include false alerts, will vary depending upon the system installed and the number of sensors used.
Finally, why is the demand for these systems growing? Most everyone has heard about the active shooter events that have occurred in all business and educational environments and would like to see these events eliminated or the lives lost greatly reduced. There are two primary ways that these shot detection systems can assist in reducing the impact of these events.
The first is to create automatic alerts to the local authorities, reducing the
