I can’t speak for all. But in Norway it’s illegal to have a doorbell camera that records the street.
It’s also very limited for police to set up recording cameras. They need to serve a special purpose. So you will have some in city centres and places where there’s a lot of people, for crime prevention.
In general the right to personal data is extremely well protected under law. Both offline and online
I don’t data hoard. That I pay usenetserver to do for me. You could never hoard all that anyway, and nor should you.
