Drone surveillance is the use of unmanned aerial vehicles (UAVs) to capture still images and video from a distance or at a high altitude to gather information about specific targets, which may be individuals, groups, or the environment.
Drones' small size, ability to fly, and withstand harsh environments mean they can often survey objects that may be out of reach and can get a first-person view that photographers don't usually get. Nowadays, security drones equipped with live video cameras, infrared cameras, thermal sensors, and LiDAR are used in large numbers by law enforcement.
