For cameras, it's a mix. Mostly chinese P.O.E. largely from Amazon (Jidetech - $39 possible, Sunba - $250ish, etc.) some PTZ, but they are not internet connected - all segregated into their own POE lan. (Don't internet connect any cameras, period, they are the #1 hacking entry point). The server - which has multiple NIC's of course, is internet connected through a separate interface, and can present video/pictures etc. from these non-internet cameras through the Blue Iris app / web interface.
For laypeople,
POE = Power Over Ethernet, it means you don't run power to any camera, you just have to make sure your network cable makes it there. Special routers "inject" power into spare wires of the network cable - and it can power well over 100' away on most cameras. It makes installation much easier and makes them more weatherproof.
NIC = Network Interface, e.g. servers have multiple network cards/network ports, so one network port plugs into your camera router (which has no internet) and the computer treats that as network #1, your other network port plugs into your regular router/gateway, your computer treats that as network #2 (which has internet), and they are segregated from each other. You can also get this by buying network cards and putting them into the PC expansion slots on the motherboard of a regular desktop.
....so even if the server is hacked, they can't access the cameras, because they are not, in any way, internet connected - worst case, archived recorded files would be exposed in severe "nation state" style hacks.
...yet, Blue Iris (server) can still send out notifications to your phone including screenshots, you can access BI through your phone, etc.... and B.I. is going to be inordinately harder to hack than the physical cameras, by many, many orders of magnitude.
