I meant to wave my camera around during the movie to see if it was illuminating much of anything...but I've been to my dad's office, where they have done image recognition of wheel hubs...and the IR array they use--the one that's meant to illuminate the hub--is *very* warm--almost like a heater. After all, IR is just another name for heat. I would think this array would actually make us feel warm if it was meant for illumination...and I don't think it's a jamming device anymore, either, because it doesn't seem to be high-powered enough.
I'm going with audio/captioning for the hearing impaired, though I thought they used RF for that...but with that many theaters in one location (they have like 20) I guess you'd want a signal confined to one room.
