Private investigators can use drones for many purposes, depending on the laws where they do business. For example, drones can be useful in litigation cases requiring aerial footage of a crime scene or search grid, as well as aiding with accident reconstruction.
Drones can also help with pre-surveillance planning, helping the investigator map out approach and exit routes and the best sites for stationary surveillance. They’re useful for finding out out what vehicles are parked at a particular location. And drones are also beneficial for photographing areas that are inaccessible by foot or vehicle, such as over water or in rugged, remote areas.
