Omnilert delivers a proactive, AI-powered gun detection and automated response solution that leverages existing security cameras to help prevent active shooter incidents by identifying firearms the moment they are brandished. Once a gun is verified, Omnilert’s open network system seamlessly integrates with your existing security infrastructure, triggering a rapid, multi-layered response—locking doors, alerting first responders, providing real-time intelligence with images, location, and video of the shooter, and sending immediate warnings and guidance. By reducing response times and delivering actionable insights in seconds, Omnilert not only helps mitigate threats, save lives, and reduce the operational, legal, and social costs of gun violence but also connects with trusted security partners and evolving technologies to ensure maximum flexibility and comprehensive protection for today and the future. Recognized by the U.S. Department of Homeland Security’s SAFETY Act as a designated anti-terrorism technology, Omnilert’s patented solution is engineered from deep experience in military defense technology but tailored for commercial and public safety needs. Since its founding in 2004, Omnilert has been a trusted partner of organizations across many industries, including K-12 schools, higher education, government, healthcare, retail, enterprise, corporate campuses, manufacturing, critical infrastructure, transportation hubs, entertainment venues, and places of worship.
