Gunshot Detection Systems use an array of sensors placed throughout the coverage area to detect and communicate the location of a gunshot source. Militaries, law enforcement, and security agencies frequently employ these systems to determine the direction of gunfire and the source and type of weapon used. They provide the situational awareness required to respond to hostile attacks quickly and accurately, allowing the public to be better protected from snipers and other gunfire threats. Furthermore, such systems may have military applications, allowing soldiers to detect and localize enemy fire on the battlefield. The market for gunshot detection systems is uplifted by the rising demand for advanced security systems. Shooting in cities poses a significant threat to public safety faced by law enforcement, ambulances, and other rescuers. According to the Centres for Disease Control and Prevention, nearly 81 people were killed by gunshots in the United States every day in 2004, or one every eighteen minutes. As a result, demand for gunshot detection systems has been steadily increasing to provide advanced security systems and improve public security. These systems are found on armored vehicles, soldier armor, border crossings, and military installations on buildings and bases in militaries.

Because law enforcement agencies and militaries are focused on protecting the public, apprehending criminals, and gathering forensic evidence for investigations, gunshot detection systems are expected to be widely adopted in these fields. Law enforcement agencies have deployed gunshot detection systems in high-crime urban areas to reduce the use of illegal firearms and, therefore, obtain better real-time geospatial information on shootings in public spaces. More than 90 cities have adopted this technology, including New York, Milwaukee, and Miami. In addition, one of the fastest-growing market trends is the installation of gunshot detection systems as part of smart city projects. The Indian government concentrates on developing 100 smart cities and has already set aside funds worth 98,000 crores (USD 980 billion) for this purpose. For example, the crime rate in Surat, India, has dropped by 27% since implementing security measures based on artificial intelligence.

Gunshot Detection System Market Growth Factors

Increasing Incidences of Shootings in Public Places Are Driving the Market

In the United States, major cities have begun tracking gunfire or gunshots near schools, colleges, and universities, as educational institutions increasingly face gunshot attacks that endanger students and staff. The Federal Bureau of Investigation (FBI) detected potential gunfire targets in a study of 200 active shooting incidents. According to the survey, shootings in commercial areas accounted for 44.0% of all shooting incidents, while shootings at educational institutions accounted for 22.5%.

A gunshot detection system can be installed both indoors and outdoors, and it provides coverage in the event of a shooting attack. When a gun is fired, the loud explosive sound activates a network of sensors, cameras, or both, which sends summarised data about the acoustic event to a review centre where acoustics experts review and classify the sound. Gunshot location technology can be used in any size building with many floors. The incident detection area is the coverage range within which shots fired will register with the technology and trigger the alert. As gunshots and gunfire become more common in public places like schools, colleges, and universities, the demand for gunshot detection systems increases.

Rapid Response to Local Authorities

A witness called may be a great way to encourage faster dispatch and prevent crime. Still, some people may be hesitant to call the officers or be in a state of panic, resulting in the wrong demographics being provided. Providing accurate information to the police during a gunfight is critical for a quick response.

GDT was designed to identify, authenticate, and notify officers within seconds of detecting a gunshot. Specific times and locations of gunfire are included in the data. Several acoustic sensors gather data and triangulate it to determine the source of the sound and the date and time. The audio is then sent to law enforcement, and the data can either be verified as a gunshot or dismissed as a false alarm.

Crime Prevention in the Locality Giving A Push to Market

GDT provides data that crime analysts use to spot trends, locate gun violence hotspots, and create maps that assist law enforcement in making tactical decisions about where to deploy patrols and other resources. This analysis can also encourage social workers to recruit community members who want to help with a street outreach to prevent conflicts between social groups, crews, and gangs from becoming more serious. Though residents must continue to report gunfire incidents, GDT is an effective tool for addressing firearm violence because it generates a comprehensive report that allows for faster Response and lowers crime rates.

The High Installation Cost of the Gunshot Detection Systems in Cities

In homeland security applications, gunshot detection systems are widely used. These systems are costly because they require installing many spatially distributed sensors over a large area. These systems require additional maintenance.

Market Opportunity

Security of Emerging Smart Cities

To improve security, futuristic smart cities are expected to use cutting-edge technology. Gunshot detection is one of the technologies that is helping to improve civilian security services in cities across the United States, such as Fresno, California, and Peoria, Illinois. These systems provide forensic evidence to law enforcement and security firms for gunshot investigations. Gunshot detectors are digital microphones installed on buildings and streets that record evidence of gunshots, provide near-instantaneous notification, triangulate the location of shooters and the direction of a shot, detect the type of gun, and help catch fleeing suspects and solve crimes.
