Security cameras afaik usually don't record audio, but all phones can. And they don't even need to be pointed in any specific direction.
On a separate note, (and this is a genuine question) are you by any chance aware the term Non-consensual intimate imagery / NCII?
I am beginning to suspect that the average HN goer isn’t aware of the scope and scale of the Trust and Safety problem.
Smart glasses, however, are always aimed at whatever the wearer is looking at. They may or may not be recording (note the reports of people hiding the LED indicators), and at a fair distance could easily be mistaken for a normal pair.
The general populace is much more likely to notice the former recording rather than the latter.
Just because you don’t notice it doesn’t mean it doesn’t happen.
However, this is still a different thing than smart glasses which can further be segmented into who designed the smart glasses.
