Drone use by burglars is going to become a problem, imagine the ability to check the yards for dogs, whether cars are in the driveway, which model of cars are available for stealing or parts, etc all without having to enter the neighborhood or gated community until you are ready to make your theft raid.
Think of camping in an area of mostly empty summer or winter cabins and being able to research and plan your quick in-and-out burglary strikes from your campsite or motor home, or car.
Maybe there’s already some kind of motion detection device which let’s the home owner know if any drones have been flying overhead below a certain altitude and within a certain time frames. It’s a defensive response vs offensive. Better than nothing.
