Unsurprisingly, this technology, and presumably utilizing the surveillance to find any reason for eviction, is being applied to poor people. You rarely find this being rolled out in luxury apartments. Let's be honest here, poor people are stereotyped as being lazy, sneaky, untrustworthy, and stupid, so they have to be subjective to a more paternalism.
I thought it's not uncommon for luxury NYC apartment buildings to have a 24hr concierge / lobby attendant who's main task is to keep strangers out. (In Hong Kong this is pretty much the norm in all residential buildings, upscale or cheap government subsidized ones alike.)
To memorize not only each resident's name and face, but also those of their occasional out-of-town guests, is quite a feat.
