No, it does not change the settings on the camera...it only changes the rate at which it feeds frames to icamsource. If you were to use that same URL in your web browser (I think it'd need to be Firefox if on Windows), but remove the rate limitation, you should see pretty fluid motion (assuming the internal camera settings are set to 25 or 30fps...and assuming the cameras have a strong wifi connection). Were you able to login to the cameras' webpages? I have a FOSCAM knockoff (LOFTEK), and I would think the web interface would be very similar. Mine has a fps setting on the page that displays the camera feed, along with a frequency (50Hz, etc) setting, resolution setting, and some other stuff. Do you you not have that?
