...uh no? If the camera is physically not pointed at you, it can't record you. It's clear and concise.

EDIT: My exact thought on this subject has been that the camera needs a mechanical shutter. But I'd say thinking of Glass like sunglasses is probably also the way to go - a way to "take it off" without having to take them off (i.e. like when you put your sunglasses on your heard to talk to someone indoors).
