I suppose you could use one of those sub $100 security cams. Those typically
have IR LEDs right next to the lens to illuminate in the dark. They are
certainly sensitive to IR.
I caught some raccoons prying open the cat door with one of those. A closer
examination on how they opened the supposedly locked door helped me outsmart
the buggers :-)
Anyway, get a wired version (the 2.4 GHz ones generally suck) and be amazed
with the image quality. I record it 640x480 in Divx format right onto my
hard drive. My camera was a $50 special at Fry's.
