Insane idea here, have you thought about just asking him not to?

"Hey neighbor, I was wondering if you might do me a small favor. I noticed your new drone, it's very cool. I'm sure you get lots of cool pictures and footage, but it makes me a little bit uncomfortable when you're flying over my garden and my home, do ya think you think you could still get your footage from outside of my property's airspace?

Thanks pal, I appreciate it."

OP mentions that he doesn't know which neighbor owns the drone. If he's in a neighborhood like mine, he may only have line of sight of his most immediate neighbor and past that it could be any of dozens of other houses within close proximity.

Hm, I skimmed over that.

He may have to follow the drone home next time he sees it.
