I've got the FI8904W (FI8098W still in the post) and just got it setup today, I think setting it up with iCamSource was the easy bit!
What you can try is, if you click on the URL link where you enter the camera address, it will take you to the SKJM support page, enter the details and it will generate the link for you.
Select the MJPEG link, paste it in add username and password and that should do it.
Hope that helps.
