Drones for surveillance are unmanned aerial vehicles (UAVs) that are used to monitor and observe areas from the air. They are equipped with cameras that can be used to capture images and videos of the ground below. Drones are often used by law enforcement agencies, militaries, and other organizations to monitor large areas or to survey terrain or buildings. They can also be used to observe and track individuals or vehicles in order to help identify potential threats or criminal activity. In addition, drones can be used to provide search and rescue teams with an overhead view of an area, or to deliver supplies or medical aid in remote or difficult-to-reach locations.
