Has anyone ever tried anything like this, using infrared cameras to find a cave entrance? Seems like a good idea to try....

Re: Locating new caves
One of my profs in college took a job mid semester in Washington to do that the flew infrared cameras over winter landscapes looking for the heat difference to find caves.
Cool project, but that prof was a douche.

More online investigation than onsite exploration these days.

RE: Locating new caves
I wonder if you could just use any low cost infrared camera and walk around the woods with it or if you'd need some expensive one? Or how accurate it is?
Re: Locating new caves
I don't know but digging out a cave would be a lot of work.
Btw I'm a douche. That is all...

When they were digging into the cave all I could think of was if they were at the top of a large dome digging in. Like what if they dug into the top of the big room of marvel cave...

Re: Locating new caves
The cheap IR cameras you're thinking of actually use a night vision technique called Near Infrared Illumination. Basically they emit their own IR spectrum light and allow you to see in the dark.
For finding the heat signature of a cave, you'd need full on thermal imaging. This technique detects IR heat energy, whereas the near infrared illumination only detects the IR light put out by the camera itself (usually with little leds).
