I plan to use my Pi and the Pi camera v2 no IR version as a wildlife camera. Now my question is can I run the camera in the winter (maybe -10 degrees Celsius) and will it still work like the Raspberry Pi? My other question is can the Raspberry + camera survive some dust?
Raspberry Pi devices themselves do not have any proper International Protection Rating, therefore device itself is not recommended for such usage. From my own experiences, Raspberry Pi devices can survive temperatures as low as -20°C(at least one in my backpack worked well) but need to be treated as a bare motherboards - with great care, far from any dust/electricity conducting materials. I'd suggest finding proper case for the Pi AND the camera before risking the damage.
