Yeah good questions, I think you'll always end up with a long cable plugged into the pi, so through a window or something. They don't usually need external power sources so that's good, the pi should be enough.
I have a tree just outside my window so I'd plonk it on that, but it would have to be weatherproofed.
Some of the setups I saw they just ran lavalier microphones out through a window.
I can’t do that at my place so I’d probably get an outside power supply, enclosure, and a mic that I can run out of the enclosure.
Yeah some kind of microphone through the window sounds like what I'd try.
You could probably do it with some kind of battery pack too, though having to recharge that all the time is a pain in the ass.
