scoot12: Here is another link with Reconyx camera comparisons, prices etc. http://www.reconyx.com/page.php?id=138
Comparing the PC800 to the HC500, I would go for the PC800:
HC 500: 1 year warranty
temperature range -20 Degree F to +120 Degree F.
50 ft. range
PC800: 2year warranty
temperature range -40 Degree F to +140 Degree F.
Infrared flash range up to 70 ft.
The PC 800 costs $100.00 more. I feel the addtional cost is well worth it.
I live in Canada where It can either be pretty cold in the winter with no
wind or warmer with a high wind giving a very cold wind chill. The majority
of the trail cameras will not operate in lower temperatures unless coupled
up to an external battery which gives a much larger power source.
Cameras exposed to the sun in the summer can be subjected to high
temperatures.
