Doesn't have to be. Here in the Netherlands it's actually illegal to (permanently) film public space, and people can and will point that out to any offenders.
They are everywhere. Knowing the old “Germany is the land of privacy” I was shocked to walk about in many neighborhoods, from pretty run down to affluent, and see Ring, Nest, Arlo, all cloud connected cameras hanging over doors but turned more towards the public road in front of the house.
There's permanent cameras pointed at the street in the red light district in Amsterdam, along with warning signs saying that photographing the women in the windows is illegal.
