Such IR LEDs have been suggested as a way to defeat facial recognition cameras and license plate readers, because most such devices are not IR shielded, so the IR light “blinds” them in the same way a bright flashlight temporarily blinds the human eye, without appearing to the naked eye to emit light at all. They may be attached to a hat or cap, or placed to surround a license plate. DIY Instructions may be found online.
