The difference is "recording". Or, more specifically, recording and never deleting the recording.

I guess it isn't so much the surveillance itself that bothers me, its three things: 1) the idea that technology now allows surveillance to be ubiquitous, 2) that the security guard's observations don't attempt to identify me and observations don't "persist" across multiple visits/venues, and 3)that all the surveillance data is archived forever - ready to be abused/sold/profited-from whenever somebody thins of a way to make a buck out of it (or, more paranoid/cynically, invents new retroactive laws then goes looking for past indiscretions…)
