Cold Weather possible fix?

[DannyUPNorth]

I have 4 cameras. I have 2 hooked up with solar chargers and two without. Of the two with solar chargers the one that is in the ideal place for maximum sun angles has yet to shut down and the temp stayed between -7° and -28°F for 5 days. The solar one that doesn't have a great angle shut down once but I will build a platform to put it on to get is angled right.  Have also ordered 2 more solar charging panels and plan to set them up the same. I am also going to cut a cover out of 3" thick pink foam and put it over the camera shells just because I have it handy.

One thing I found in the past is that if I change the camera housing to black instead of white during the winter months, the cameras will charge on nice sunny days even when the ambient temperature is below the normal charging threshold.  Older cameras had silicone covers that could be added, but the newer cameras require the housing to be swapped.
