Active shooter detection systems are an important and evolving field of security technology, used to detect and alert medical personnel, law enforcement, and other personnel of active shooter incidents unfolding in real time. These systems can also be used for rapid response, enhancing coordination with first responders, and providing data for post-incident analysis. Based on the official business definition set forth by the U.S. Department of Homeland Security (DHS), an active shooter detection system is a technological solution that automates detecting, locating and identifying individuals engaging in hostile activity or exhibiting behavioral threats in private or public spaces. This system utilizes audio, video, optics, sensors, Artificial Intelligence (AI), user feedback, and other technologies to detect anomalies that can pose harm to people and property.
