Jason, he used a simply infrared thermometer.

Is he using some kind of infrared night-vision device?
Anything that produces heat will show up on that. Soldiers
use such devices to see the enemy at night -- living,
warm-blooded bodies will show up glowing brightly against
the darker (cooler) background. If he is using an infrared
viewing device, he will see the heat given off, and that may
be what he is interpreting as infrared light.
