Good question. Anticipating somewhere between $100-$200, but that’s a wee bit flexible if the end results would be worth it.
Problem with a waterproof shell for our DSLR is wanting to use it for other things. Even if it’s mounted somewhere, taking it in and out will likely throw off the angle enough to be jumpy. I’ll look into pricing out a basic DSLR, a case, and an intervalometer—let’s see how ebay works out.
The digicam idea is good too—I didn’t think to match those terms in Google. It seems there are a few out there that combine all-weather housing and interval shooting. My quick glance only shows settings up to 3-minutes, but there could be more. The Canon/CHDK combination is also worth looking into.
I also have a wireless-enabled NAS that ostensibly is set up to connect to security cameras. That’s a whole other avenue to look at.
So far, I was hoping that something like this would have everything I needed/wanted, but don’t know if they’re gimicks that will be a letdown or exactly right and I’m overthinking things.
