San Mateo Country, in California, after a successful test at the country’s Youth Services Center at the beginning of April 2019, has launched a drone detection system to protect critical facilities like jails and courts.

The center includes juvenile courts and detention center with open yards where drone could conduct surveillance or deliver contraband. The detection system showed a large number of drones operating in the air nearby.

The technology includes long-range detection and early-warning systems that track the drone’s flight path and position, as well as the pilot’s location, on the same map. It also can tell the difference between commercial drones and hobbyist drones, while a built-in application identifies threats.
