Yes, that is what you need.
Note that if you are trying to segment those cameras, it is up to the Win7 router to filter what the cameras can and cannot access on the pfSense LAN segment. pfSense is not involved in communications between 10.0.1.0/24 and 10.0.0.0/24.
You will have a pretty hosed asymmetric routing problem there that might help keep reply traffic from making it back though.
I would, personally, use another interface on the firewall for that. If you need the windows PC on that segment, put it there.
