replying to lots of people but not using quotes or reply will be a mile long

cameras are good ip rated, and they last a long time, but temperature fluctuates a lot, a few of them are in blast freezers where they're empty, then loaded up and pulled down to -30, few days later it's emptied (and left open) filled again and back down to -30.... leaving them empty so we can load/unload without needing a load of warm gear on

link works for me too now, not sure what was going on

I thought about enclosures but couldn't find any that looked decent or weren’t a fortune

guess I'll just go with a small heater and hope it loses heat quick enough to not get too hot

I assumed there'd be some kind of industry standard low power anti freeze heaters that I just didn't know about

older external cctv cameras might be a better thought as they are designed for really bad external weather

but extreme weather which is what your on about needs a better camera and there not cheap
