I'm interested in the TP Series long range IP cameras for use at our business to get a good view of the parking lot across the street.  Unfortunately being in Wisconsin we also have winter weather -20F and below.

If these cameras were mounted on the side of our building, what would you recommend to protect them from the cold weather?  We currently have dome analog cameras that have survived several winters, but they just don't have the video quality to get a clear enough image at the distance we need.

Thanks, Brian.
