Here is another solution for removing unauthorized drones from your air space safely. The DroneCatcher is a multicopter with a netgun. It can shoot a net to capture rogue drones and move them to a safe zone. It can also deploy a parachute for heavier threats.
The DroneCatcher can approach hovering and moving threats rapidly. It uses sensors to lock on to the target and launch a net. The above video shows it in action.
