Hmmm
I think being introduced to someone who then produced a IR camera would freak me out

yeah, but it's near IR*
it will just give you a picture that looks like a funny coloured version of an ordinary camera, as it will only pick up IR frequencies near the visible spectrum.

You want far-IR to get proper heat tracking. The stuff that's heading down towards radio wave frequencies.

*I'm assuming this, based on the £18 price tag.
