You set up the second NIC with a fixed IP address. You set up the cameras with fixed IP addresses on that same subnet scheme. Everything is accessed, remotely, using either the Blue Iris app or UI3, the web GUI built into Blue Iris. If outside your own LAN, use a VPN so it's like being on your own LAN. The only direct access to the cameras is from the machine with the second NIC.
