I wouldn't expect anything like predator vision from my set up, but you're
definitely right.  I'm wondering if I'll see anything at all (obviously
while minimizing other sources of IR in the area I test it in).  Everyone's
favorite dictionary has some info on the ranges in question:

My setup worked more like traditional night vision.  TV remotes become
flashlights.  Still a cool project.
