I live in ND and I use my stealth cam in weather down to 0 F or lower. The battery life is not very long at all and it will never rewind by itself you need to have brand new batteries and manual rewind it with the button. When the batteries where down some times it will not advance the film but it will keep counting so you don't have a clue how many pics are on the film. I always you Kodak film generally 800 it is better at night. good luck
