How about
eth0 eth1
box1: 10.0.1.1 10.0.0.1
box2: 10.0.1.2 10.0.0.2
camera1: 10.0.0.3
camera2: 10.0.0.4
Each interface would have a netmask of 255.255.255.0, and you
could, then, plug the 2 cameras, and the 2 eth1 interfaces into
a hub/switch. This way, you could have a little 4 node network
since both cameras would also be on the 10.0.0.* network. And,
both box1 and box2 could view the output from camera1 and camera2.
Both eth0 NICs could be plugged into a 2nd hub/switch,
and then head to the "main" network.
Any video that you wanted sent out to the main network would
easily be gatewayed from eth1 thru eth0.
