NIC1 (eno1) is red on the left; NIC2 (enp2s0) is white on the right.

The primary interface is on the left, closest to the display ports (the red ethernet cable is attached to the primary NIC in the above photo).
The secondary NIC is to the right of that, closest to the "DC IN" power port (the white ethernet cable is attached to the secondary NIC in the above photo). Connect the primary NIC to your WAN and the secondary NIC to your camera LAN via standard Ethernet (Cat6) cables.
