Wireless Spotlight Cams with Solar Panel in Colder Climates

Does anybody living in northern United States (Wisconsin, Michigan, Minnesota, Etc.) have wireless spotlight cameras with and without solar panel? Are they working for you? Or is it a big no-no considering the cold temperatures we get here? I'm in Southeast Michigan. I cannot get wired ones at this time. I cannot invest in extensive electric wiring and I'm kind of in a bit of a situation right now. Therefore, I'm considering the wireless spotlight camera with solar panel until I can move to an electrical installation. But they are not necessarily inexpensive. So if they are not going to work in our current weather conditions, I don't want to spend the money. Thanks!
