If there is some system that is supposed to benefit the public then its designs should be public and subject to public approval.
What would be reasonable would be something like open source designs and protocols and maybe an electronic bidding system for projects.
But it sounds like its one company embedding whatever spy-tech they want and controlling everything over a large area behind closed doors.
I actually am really looking forward to smart cities. But smart as in high tech and advanced, not smart as in monopolistic surveillance dystopia.
