How to Protect Against Drones

Both the Tokyo police and the Human-Interactive Robotics Lab at Michigan Tech are using nets to catch smaller hostile drones. The idea is very simple: shoot a net or lure a drone into a net, entangling it. This electromagnetic field gun can safely bring drones down to the ground. However, it's not commercially available yet, and radio jammers are illegal in the US. DroneShield's Omnidirectional Sensor and Long-Range Sensor can remotely detect drones that are undetectable by radar.
