You could create virtual or dummy interfaces (I don't usually recommend virtual interfaces since you can usually assign more than one IP to the physical interface or you have a sophisticated bridging toolset, neither of which is going to help you in this particular case).
Basically I imagine something like this: "sudo /sbin/ip li add dummy0 type dummy" and then again for a dummy1 interface. Bring up the fake interface with "sudo ip link set dummy0 up" and assign an IP to it with "sudo ip addr add 192.168.1.1/24 dev dummy0" and then a different IP from a different subnet on the other dummy interface. From here you set up a NAT with the dummy interfaces acting like the external interface and the real ones connected to the cameras as the "internal" interface. All the usual NAT things like forwarding will need to be enabled. Hopefully this is not for a production environment. Ideally you would need to be able to change the IP addresses of the cameras to play nice on their respective networks, since what I have outlined will be a pain to maintain. You might get lucky and these cameras might support IPv6; "sudo ip neigh is kind of like arp but will also show IPv6 addresses (this is the short short description of "ip neigh", the reality is a little more complicated under the hood). If you are lucky you will see link local IPv6 addresses that are listed as "REACHABLE". You might then be able to connect via the IPv6 address that starts with fe80.
