Even from a security point of view, that's only true if they actually use it effectively. From direct personal experience, this is not always the case: just because a camera is there, that doesn't necessarily mean anyone will bother to check it, even following the theft of a considerable sum of money. I suppose in theory, if you blanketed the entire country with CCTV (just one town is no good, the crime can move to the next town over) then you might have a deterrent effect, but of course all the other concerns about mass surveillance would still apply.
