Okay guys..... Here's the camera that we're using:

It has auto-humidity, temp control, auto-iris, etc
I didn't get the details of the setup for the computer at the field. Basically, it is a MAC with a digital video capture card that takes a snapshot and uploads it to our club's server. I'm trying to see if we can get a broadband service to the field to have DSL, but doesn't look good (24,000 ft from CO). We're out in one of the few remote areas of the silicon valley that doesn't have service. We're also going in install a better capture card that will make the images much larger.
