My has been outdoors (sheltered ceilings) throughout the winter and it still works!
It has passed temperatures down to -20, snow, rain and debris as well as hot weather, but as it is said, it is sheltered under roof so it is not exposed to snow / rain directly to the camera.
Really good camera, pulls off a star because it sometimes gets a bit of play when it's recording. However, do not know if it's the app or the camera itself, but I've set up the camera to record 2 minutes in motion, it's up to 99% of the times but sometimes when I'm watching a recording it says recording is everything from 35 minutes to a couple of hours.
However, after a while, I'll get up and I'm watching the recording the day after, it's only recorded for 2 minutes.
