Unmanned aerial vehicles (UAVs) are experiencing a major increase in popularity in both consumer and industrial markets as prices fall and the technology matures. No longer are drones limited to military purposes as manufacturers begin to mass produce civilian models, ushering in a new era of transportation technology. While consumer drones are still in their infancy stage, there is little in the way of rules and regulations regarding privacy issues of these new devices. In this paper, we design an energy efficient off-the-shelf hardware system capable of detecting and selectively disabling video feeds of WiFi based consumer drones if they enter a defended area.
