Well, I guess whatever camera you get should give you a power requirement and you can work backwards from there as to storage and panel requirement. My off the cuff notion would say you’ll need a deep cycle or a group 31 of 100aH to last for a day or two depending on weather and length of day, and lithium batteries will get plating if you try to charge below freezing so they’re out.

It’s all in the math, then double it because nature hates you.
