In the US, photographing and recording police are first amendment-protected activities.
Likewise, the fourth amendement doesn't forbid a police officer from recording someone in public, because there's no expectation of privacy when out in public.
The courts have found that legally, one officer recording one person is no different from a large-scale, automated surveillance system recording everyone.
Well, that argument goes both ways. If the scale and automation don't make a difference, they don't make a difference.
