It seems to be the opposite near me. There's a few well off neighborhoods that I've noticed have cameras all over, but the area near my work where there's new piles of broken glass every morning has nothing (not that I want more surveillance, but it makes the intent clear).

The neighborhoods that are less well off I spend less time in, so maybe I just haven't seen them, but usually surveillance there seems to be in the form of parking lot camera trailers.
