I'm sure there are areas, especially in London, where you can be continually tracked on cameras. But I think we were in Docklands one time and someone was told not to take photos as it is private land. Ages ago I looked at some site that gave access to loads of online cameras. I expect some use 'AI' to monitor what goes one. Our doorbell tries to tell if someone coming to the door has a package with them. I heard some may do facial recognition and that gets tricky when it comes to privacy. What would Orwell say?
