I live in Alberta, Canada where it gets pretty darn cold for most of the winter. Sometimes my Bushnell Trophy Cam shuts down when the temperature gets around -20c (-4f) or lower.

This camera is overlooking my yard. I'm wondering if using a DC adapter instead of the batteries would allow it to keep functioning in a deep freeze. This because there wouldn't be the voltage drop you get with cold batteries.

I guess it would then only be limited by what cold the cameras internal components can handle?
