Question

CCTV

Answer 1

Maybe.
You need to get at least one white ip - then the task is easier to solve.
At all points where there are cameras, you need to organize access to the Internet.
Next, you need to study the question - which cameras, what their firmware can do (and for sure, your cameras cannot connect to the provider's Internet and vpn), is it possible to connect a usb modem directly to the camera, or even insert a SIM card into it, and so on.
