Abstract: A security system includes an autonomous unmanned aerial vehicle (UAV) including an airframe with a power source and a propulsive system operatively mounted to the airframe for sustained, autonomous flight of the UAV. A flight control system is operatively connected to the airframe, propulsive system, and power source to control the sustained, autonomous flight of the UAV. An imaging device is mounted to the airframe. A wireless communication device is operatively connected to the imaging device to wirelessly transmit data including images from the imaging device. A remote server is operatively connected to receive the data transmitted wirelessly from the wireless communication device, wherein the remote server is operatively connected to communicate the data to emergency responders.
