AirRing is a drone-detection radar for critical infrastructure, businesses, and homes. Twelve radar panels form a half-meter dome that watches a site’s low-altitude airspace in every direction, including the sky directly overhead. When a drone enters that airspace, AirRing immediately shows where it is and where it is moving on screens and phones. The system delivers three values. First, users know the moment a drone threat appears—without blind sectors, day or night, across changing weather conditions. Second, AirRing makes military-grade drone detection accessible to facilities, businesses, and homes—without the size, cost, and operating complexity of conventional systems. Third, users can install it on a rooftop, pole, or tripod, move it as needs change, and maintain it easily through modular panels and no rotating parts. One dome monitors the airspace above a property; added units extend coverage across a larger site. AirRing brings security to the sky—from infrastructure to homes.
