Instagram shows me too many videos of "pick up artists" doing POV videos of their douchey interaction with girls, recorded on these. I wonder if it's too stealthy that the people being recorded don't notice. Slash, maybe they have release forms and the videos published are just the ones where they consented to being recorded (heh, as if the pick-up scene cares so great about consent...), and the failed ones are where they immediately say "Is that a camera? Fuck off!".
It does have a glowing LED: https://youtu.be/X95mWoTgjaE?t=105 but I feel like they're easy to hide with some black tape.
