If the MJPEG or JPEG URL isn't something that can be found by searching around with Google or by contacting their support, we actually have another solution available, although it is currently in its very preliminary stages, and that is:
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
If you already have port forwarding configured on your router, I would like to try and confirm that your port forwarding is functioning as we expect it to. If you visit this link in your computer's web browser:
http://portchecker.net/udp.php?p=12001... it will open a webpage that contains a Java Applet in it (similar to iCamWeb) that will be able to listen on port 12000 for a UDP packet to be sent from a server on the Internet to your computer.
If your port forwarding is functioning correctly then you should see a message saying that the port is "open." If it is not functioning correctly, it should say that it is blocked.
Also, please send me a screenshot of your router's port forwarding configuration to support@skjm.com, so we can verify the settings. Please reference this post and your username in your email.
