Security cameras are fine for filming your own property.
Any cameras are fine for recording any public property. That’s the whole idea of being in public: others can see you, you can see them, and you aren’t (shouldn’t) be doing something you wouldn’t mind being recorded. You have no expectation of privacy standing on a sidewalk.
50 years ago you didn't have privacy walking around outside but you weren't subject to constant surveillance and tracking. The current state isn't some inevitable fact of life. It's fixable without any draconian action.
