The real estate drones used to get a bird's eye perspective in stills and video needs to be registered with the FAA. Back in the end of July 2015 the National Association of REALTORS had an opinion on aerial real estate drone use.
Quote "Given the current FAA prohibition, the National Association of REALTORS® recommends that its members not use this technology for any purpose related to selling property."
We have had a drone for real estate photography, videos since early in 2014.
The quad copter drone uses, carries a Go Pro camera not the big model we have in the video arsenal.
Which would be too heavy to lift tree top high.
Like anything, a good thing can be used for harmful purposes.Drones are no different in the wrong hands.
And accidents happen when a drone goes astray or is too close to an airport.
The take off, landing of real airplanes, helicopters needs policing. Rules to regulate drone aerial photography were pretty wild in the beginning. Needing a pilot's license batted around.
A the FAA, the public, the media thought about what was needed. To sky marshal herd and police the swarm of drones. As lawmakers came to the party way way late. After the drones were already out of the barn.. I mean DJI box.
