Today drones are used for search operation like SAR to find lost persons or victims in area where physically human search is costly and less effective. Drone offers aerial vantage point to cover much more larger area. When added by low light or infrared camera, drone can detect people in low visibilities. In addition, the drone is useful either for delivering important things for victim such as water faster than transporting it with standard carriage. It is often that drone is used to deliver important tools to rescuers in hardly reached places.
SAR operations in night situation will require light source to cover dark and large areas so SAR drones equipped with special lighting will help much from altitude so rescuers can locate and navigate their searching task. In other hand, victims or lost persons can spot the light and respond it effectively to be found by SAR team. In large scale disaster situation where many infrastructures have destroyed a drone can bring very useful information to rescuers concerning with condition of roads to be passed and to locate survivors.
Among drone for SAR classes is DroneBase Gemini (HD + VIdeo + Thermal Dual Camera). It comes with onboard 16MP Sony EXMOR CMOS daylight sensor parallel with FLIR thermal sensor. There is also DJi Go App Ready plus Thermal/Daylight Video Feedback and advanced remote control for FLIR Camera, Geotagging System and Target Lock.
Dronebase Gemini Pro (HD 10x Zoom Video + Thermal Dual Camera) comes onboard full HD 10x optical zoom @ 3MP daylight camera parallel with FLIR thermal camera. It is also equipped with Horizon computation system with dual IMU, Onboard Daylight FUllHD 3MP camera, FLIR Ready, Advanced remote control for FLIR Camera and Real time Geotag System.
There are many other SAR Drone classes we can find but at least two above can explain general specifications found in drones at this class. In conclusion, drones for SAR operations play important roles to rescue victims or lost persons as fast as possible. Long Flight Drones will give much support for rescue operation in large scale disaster.
