Getting the Dlink DCS-2121 with Time Capsule

I am having som difficulties setting up the Dlink DCS-2121 serveillance camera with my Time Capsule wireless router and the mac.

I have a Windows computer as well, so I have managed to get the web based setup interface up and running on 10.0.1.113 while the camera is connected via ethernet cable to my Time Capsule router.

My aim is to detach the camera from the router and use my wifi network so that I have a little more flexibility when positioning the camera. However, I am not able to do this. Clearly I am missing something here, but the documentation is pretty poor.

Can somebody shed some light on this for me, please?
