Not inside the US. There is no expectation of privacy when you are in public.

Not here either - I can take a photo of anyone in the street. However, I can’t mount a fixed surveillance camera on my house and do the same (for some reason).

Please provide a citation on this.

This is Swedish law (or at least clear authority guidelines). I can’t find an English link but if you absolutely don’t believe me I could translate (but just want to make sure you didn’t think I was talking about US law before I waste that effort :D )

relevant passage >

"Camera surveillance of a location where the public has access. Permission 8 § Camera surveillance is required for a surveillance camera to be posted so that it can be directed to a place where the public has access."

(In separate guidelines it explicitly mentions the case of home cameras covering public area).

Ah, ok, I thought you were somewhere in the US, in which case whoever told you you couldn't have an outdoor camera was lying to you. Thanks for clarifying.
