Looking For a Tiny IP Cam With 50mm Lens

I'm hoping you lads can help me out here.

I'm looking for a very small camera (think golfball size'ish), ip, which has a lens of 50mm of a CS mount.
We're looking for these for our Blast Furance to look inside to see if our coal is still being injected. So as you can imagine in regards in that it's a blast furnace, light sensitivity isn't really a subject here.

Any of you have some suggestions ?
