I've always wanted to sew very bright IR LEDs into a hat that would blind a camera. Your face would naturally be shadowed by the bill of the hat as that's its intended purpose. The IR would hopefully make the camera want to adjust shutter speed and gain/ISO while assuming a fixed aperture lens.

There was a fictional version of this in the Artemis Fowl books. My old camcorder picked up a lot of IR outside of visible range, but I think newer sensors are much less susceptible to this.

Wasn't there something about how the LIDAR in self-driving cars destroys camera sensors?

Depends what your threat model is, but this will literally turn you into a glowing signal that says "hey, look at me!" Your face might be protected but anyone manually reviewing security footage will be paying way more attention.
