The area with potential for innovation is drone surveillance for large rural plots. A farmer with 1000 acres and a herd of cattle may have to spend a day or two searching for a lost head. A drone could methodically surveil the plot, seeing through tree cover and working through the night with IR. I can imagine "cow tippers" of the future being tailed by a drone. The legality of this seems already settled to me. If it is legal to have fixed surveillance cameras anywhere on your private property, why wouldn't it be similarly legal for that camera to take flight, assuming it adheres to any applicable FAA regulations?
