I'm amazed you can't see the difference.

Body cam - used to protect the police and people being policed in a potentially hot conflict. Recording is scoped to these specific interactions that rarely occur for most people.

Doorbell cam - highly controversial. See response to dog-finding superbowl ad.

Body cam wore on face - Mass surveillance in potentially every conceivable social context. Data owned by Meta, a company known for building a profile on people that don't even use their products.

Door bells also had a popular movie made that revolved around their use: Weapons.

And that didn’t raise an uproar of suspicion even as one character went door to door asking if he could look at his neighbors recordings.

People are comfortable with the idea of being recorded, so long as accessing many recordings is a drawn out and manual process.

Eh, doorbell cams aren’t that controversial (ad aside). A lot of people have them already, both from ring (with the concomitant privacy issues) or from other providers (with different but similar issues).

They’re controversial on hacker news but I don’t think people in the “real world” care all that much.

How that connects to the meta glasses is certainly up for debate —- the doorbells provide a lot of value to the user (know who is at the door remotely!), the glasses are more of a mixed bag.
