How do you distinguish between a dangerous drone and a delivery drone? Traditionally to detect drones, expensive equipment would have to be installed at each facility that required protection. STRATUS instantly creates a virtual bubble of protection to track drones and perform risk assessment in real-time, no install required. Sensors provide coverage in major metropolitan areas across North America. Customers simply need a computer or mobile device connected to the Internet to use STRATUS and instantly track drones intruding in their airspace. The system enables users to define geofences and notification criteria. Users can track, report, and log drone activity as it occurs with instant text or email notification. Users can also access historical drone traffic over their facilities and produce reports showing exactly what has happened.
