My non-pan v2 survived low single digit temperatures this February (during which we also had more snow in a few days than we normally have for several winters). Back on the moving parts, however, that window heat pump unit I mentioned had developed a problem with its fan bearing when I fired it up again when the temps got back up into the upper 30’s.
As you seem to be jumping into the deep end (replacing all your cameras), I wish you luck and hope my pessimism is unwarranted.
