Surveillance drone for disaster management and military security

The concept of surveillance drones arises to aid the problem of tracking humans quickly without risking more human lives in desperate times like disasters or terrorist attacks. The design consists of a Quad-Copter with a Wi-Vi sensor, infrared camera and GPS to quickly track humans from distance on areas which are not quickly reachable from land and/or are not safe for a human to reach unknowingly. The key element here is the detection of humans below rubbles in case of disaster and terrorists hidden behind walls.
