He means the camera web interface. You need to setup the cameras with a reserved (dhcp reservation) or static ip..this has nothing to do with blue iris. Its basic networking. You need to do that before going any further.
Yeah, when i try to go directly to the camera at the default IP, it just shows a bkank page. The default IP is 192.0.0.64 and thats what SADP shows it as, as well
