If you stick a camera inside a window then any IR lights on the camera will just reflect off the glass and it'll be useless at night, but you can also just stick an IR bulb outside and illuminate things that way, which is kind of magical

Anyway this is where we seem to have ended up, so rather glad we escaped last night

Not sure about that alt-text.

If it were infrared surely the snow would be dark and the trees would be light.

@resuna Why? It's about what they reflect, not what they emit.

@mjg59 @resuna "Infrared" is huge part of spectrum. There will be difference between near infrared and thermal infrared.
