They aren’t directly connected to a social network and promoted with vast marketing resources however.

I remember playing with one of these about 10 years ago that looked like a car key fob, it recorded somewhat subpar footage in a weird format to a microSD card. A neat novelty but not very practical to use unless you really had a need to do covert surveillance of something, which most people don’t.

However if it’s made to be effortless to push watchable footage to social media, and people are heavily encouraged and incentivised to do so and it’s a different proposition.
