They’re all outdoors, although at least partially covered by something (roof overhang, gutter, etc). The cameras themselves aren’t truly waterproof and do have a “grill” cut into the back panel for the internal speaker, but since I don’t use them for 2-way audio, you can seal that off with rubber cement, flexseal, rubber tape, etc. Mine have been fine in all four seasons.

That said, all the modifications and tinkering is definitely less turn-key than some people prefer, but I’m a glutton for punishment haha

I have some V3s outside, somewhat covered by a rain gutter. They definitely get wet when the rain comes down sideways. Never had a problem.
