Sorry for being obtuse - it wasn't my intention.

I'm thinking of "Unifi Video" that is going out (EOL announced six months ago), where you could either buy their appliance OR download an official .deb package and install the NVR software on your own server.

They replace that with "Unifi Protect" that comes ONLY as an NVR appliance. No more .deb packages. It also requires you to buy one of their other products (Cloud Key 2), IIRC.
