Sounds like something you could use a balloon for.

  A drone would give you control, when you want it. You could add drone-like control mechanisms to a balloon (or a balloon to a drone -- same difference, I guess), but that adds complications, so doesn't seem worth it.

  This is true. The neat thing about the drone is that you can deploy it super rapidly though. I haven't seen it done but I am imagining 30 seconds or so.
