Comment on Infrared contact lenses let you see in the dark
Brokkr@lemmy.world 5 weeks agoYour phone’s camera should be able to “see” the IR from security cameras and IR remotes. That can give you a sense for home much and in what direction they emit.
The sensitivities will be different, your phone should still help you some.

Phone cameras have very good IR filters. They aren’t perfect which is why they can still see the LEDs, but they aren’t anywhere near as bright.
I have an old RasPi camera with the IR filter removed, a remote control looks like someone used an old-school camera flash in pitch darkness. Which is how you can control your TV sometimes even from the next room over - especially at night with no ir from the sun - shine the remote at the wall, and the wall blinks bright enough for the TV to see it, often even after a few reflections.
