That's neat. Is there any visible light in the spot? Pure Infrared?
I guess I'm wondering why the trees are so hot and the surface of the road is so cold?

It is pure infrared. The installed filter blocks out all visible light.
The LED Headlights were on the whole time for example, but they appear off because those wavelengths did not hit the cameras sensor.

The glowing effect has nothing to do with thermal radiation.
We thought so too at first and hoped for "hot" surfaces to glow.

It is an optical effect that has to do with the wavelength of infrared light. The trees glow white due to the contained chlorophyll which reflects those wavelenghts very well.
