Do we still call it CCTV if it's an IP network?

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?

I'm also non-native English speaker FWIW.

You can use IP on a LAN with no outside access.

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.

“CCTV” has better optics than “surveillance camera”.

Better as in better lenses?

Or better look (as in spyware vs CCTV). Curious, too!
