Drones users may not be covered for invasion of privacy
Recreationally used drones that fly lower than 400 ft may not be covered for invasion of privacy. Common-law invasion of privacy, or introducing onto private spaces such as homes, and the publication of private facts are two areas of privacy that recreational drone use may be violating. States such as North Carolina, Florida, Oregon, Idaho, Texas and Tennessee have already passed laws dealing with private use of drones, prohibiting the surveillance of private properties. Insurance policy holders that own drones will need to ensure that their policies cover invasion of privacy claims, as generic homeowner or commercial general liability policies are unlikely to.
Drones, also known as unmanned aerial vehicles or unmanned aerial systems, can be equipped with cameras, thermal scanners, license plate readers and facial-recognition software.

Able to accomplish feats that manned aircraft and even traditional remote-controlled airplanes cannot, they can get within close proximity of a person or property, unnoticed, and take audio-video recordings and photographs.
