Wouldn't you need a way to tell DYNDNS what your camera's IP address is? I would think that you would need a router that can updated to DYNDNS on it's own, OR, you could run the little updating program on your computer, and have your router forward a request on a certain port to the camera's IP address. Therefore, the camera would have to be on a different port, but that's probably not a big deal. Does this make sense?
