should I buy a steath cam stc I450
 

I want to buy 1 with the 12 volt battery. I think the price is right on this camera. Do other company have better than 1 year warranty. I did ask rep about a upgrade for dealing with the white outs but she has never heard of it. Does this camera work in the cold, anybody find away to keep the cam warm. Do you think I would need a solar panel to keep that battery juiced!
