It may be a fact that we all should have and are by law(at the moment)given the right to privacy. We also need to understand that this technology is here to stay. There will always be a couple of pervs that are dumb enough to try and "spy" on people with a loud non-stealth quad buzzing above. They used to call them "Peeping Toms" So now they'll have to start calling them Aerial Adams? The law will take care of them. We will, like it or not, see drones, delivering goods, transporting people etc. and just like any other annoyance, we'll get used to it. Educate people on the facts. Let them see what the camera sees. Even when only 50 ft. up, there's really not much a person with EVIL intentions can see.
I personally got the 4k to use for it's outstanding aerial video. Used to be, a helicopter or crane was needed for imagery like this. This surpasses those "old school" methods by far. My neighbors were very open to it flying 50 ft. up above, while watching themselves waving on the iPad Air monitor. They got excited watching as it took them up above the treeline and suddenly they were able to see 20 miles and the whole city. Then just seconds later 50 miles of panoramic splendor. A slow 360 pan and they were HOOKED! As drone pilots with cams, we have that magic ability to take people visually where they have never gone before. When shown the stability and handed the controller, they are all planning on their own quads! That was 4 neighbors in one flight. Mark 4 WINS in the drones for good column !!
