SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

what's possible depends on what this camera is... are they networked? usb? we can't really help if you don't actually tell us about what these things are. there's certainly no reason you can run multiple web services on different ports, apache can do that without thinking...
Assuming that the cameras are each connected to the same network, with separate network cards each, then that's not directly possible.
Each IP address on the network relates to one network interface controller (NIC), being one network card. Each NIC can have several IP addresses.
You would have to assign each network card its own IP address, and then set up 10.0.0.50 as a NAT-ing router. You can then redirect ports on the router to point to the various cameras.
e.g. let's say camera 1 is at 10.0.0.1 and camera 2 is at 10.0.0.2, and the router (any old linux box would do) is at 10.0.0.50 as in your example. You can then set up port redirection to forward port 10.0.0.50:80 to 10.0.0.1:80, and 10.0.0.50:81 to 10.0.0.2:80.
You could even set up the cameras on a separate subnet if the number space becomes a problem. The router would just need two IPs , say 10.0.0.50 and 10.0.1.50, and routing table entries to direct both subnets to the card. (Or change the netmask to 255.255.127.0 so the router thinks of it as one subnet, but that can get very confusing).
okay here is exactly what i, i just confirmed it lol,
there are camera's and these camera's will in LAN through a switch. Now ppl from other part of the world should be able access all the camera whenever they want (sort of a website kinda service u may think of). So how to achieve this using linux box?
