Closed circuit television (CCTV) is a term to describe video transmission that is not broadcast. Traditionally with BNC cables going to a control room, monitors and recorders.
I think this software-only post is meant for IP cameras / surveillance cameras. Internet is the oposite of closed circuit.
Maybe CCTV is used as a synonym for surveillance now in some regions of the world, but certainly confusing for a non-native speaker.

I think in this case, IP is referring to IP from TCP/IP, meaning "The Internet Protocol", not necessarily over/through "public internet links", so as long as you're only within your own local network/WAN, wouldn't that still be CCTV then? Or maybe the "closed circuit" thing is more of a physical property than I read it to be?
It's even recommended when building out a CCTV system with cheap Chinese IP cameras that like to phone home all the time. Stick 'em on a VLAN which can't access anything besides your local NVR.

I'm also non-native English speaker FWIW.
You can use IP on a LAN with no outside access.

“CCTV” has better optics than “surveillance camera”.
Better as in better lenses?
Or better look (as in spyware vs CCTV). Curious, too!
Yes.
Makes sense. :)
No.
