Belonging to another Hunting Forum, I came across this camera. Here is a link to the website: http://www.reconyx.com/hyperfire_detail.php?model=PC800
I found the following information worth while: 1)two year warranty, 2)operating temperature -40 degree Fahrenheit to +140 degree Fahrenheit, 3)IR flash range up to 70 feet, 4)uses 12 AA batteries for extended battery life up to one year, 5)has an external power port. There is more information on the website.
This camera would be ideal for cold weather when using Lithium Ultimate batteries. I was very surprised at the suggested MSRP of $549.00 and found it very reasonable.
