So ive reasoned that if i cover a hat, toque, or ski mask in enough IR led’s out of salvaged remote controls and provide a proper power supply, I can render the wearer functionally invisible to night vision (IR) cameras. I imagine there’s a lucrative market for such a thing.
You’d shine like a lighthouse. Great idea. It also doesn’t affect thermal cameras btw.

It’s quite the opposite. That used to be the case with the earliest models of CCTV. I’ve watched an episode on Hawaii 5-0 where the bank robbers wore IR-necklaces. Nowadays all CCTV cameras have IR-filters that block IR-light.
I’ve made IR goggles from a VR headset, an old smartphone, and an even older webcam from which I removed the IR filter. As light source I used an old flashlight with an 850 nm Osram IR-led. I can see clearly in total darkness. Bystanders see a faint red dot when the light shines in their direction.
