If that URL doesn't work, you can try our MJPEG URL tool at:
http://skjm.com/icam/mjpeg_test.phpWhen you enter the camera's IP address and port into that web page, it will attempt to connect to the camera using all of the common MJPEG and JPEG URLs that we are aware of. If any of the URLs produce an image, then that is the URL to use in iCamSource.
If your camera requires a login and password, you can enter them in that webpage right before the address : login:password@Camera_address
