Same way as the police body cameras do it: disclose what you’re doing. Which really is all OP is asking of the Ray-Ban spy cam wearers, too. A blinking red light is the conventional method.

In the police’s case, there’s rarely a choice, but at least you’re reminded you’re speaking For The Record instead of with a person. In your case, that way I know not to talk to you.

I wonder why stealth is so foundational to these devices’ success…
