Try to have the 24/7 cameras at chest level or lower, you'll find people starting to get uncomfortable. You can easily reach those angle with the glasses, and different with smartphone which also can, the glasses can be hard to distinguish.
I've said this out loud several times while reading the comments defending Meta under this post.
It's so interesting to see so many weak or misdirecting justifications. It's almost as if people are here to attempt to control the narrative for financial reasons.
If I enter a public space I consider that anybody could watch me at any time, therefore I am always careful in public and always consider that walking out of my property is consenting to anybody else seeing me. Cameras are already everywhere.
Personally I dont see a difference between someone watching me on the street or recording me and watching it back. Its just no different to me.
