That an ominous-sounding, yet totally empty and meaningless response. Most of those cameras are privately owned and operated, and would be incredibly difficult integrate into a centralized state surveillance system. We're mostly talking systems you can buy yourself at Costco:

Furthermore, a "backlash" in the case of cameras in "elevators, convenience stores etc." would have to be a backlash against private photography.

In some areas, i.e. highways in LA, they do track license plates, and there is backlash and at least concern.
A 'timed security camera' is barely related to the idea of 'ubiquitous cameras that identify you and track your movements in a government DB and input into a social credit score' a system I might add citizens have no recourse to alter.
