Or is this like some government cameras that are in public spaces filming ?
It's a nationwide network of cameras used by federal, state, and local governments to track and profile people in public. It doesn't just record, but builds a database of information on every car, license plate, and person that's filmed, so it's seen to be very dystopian.
Even worse, the tech gets it wrong and mistaken identity is common, and it ends up endangering people due to the violent methods US police employ. However, it's privacy concerns that are foremost, because there's an amendment in our country's Constitution that should prohibit this kind of privacy violation.
If you'd like to learn more, I made a YT video on the topic recently.
