Thanks for the great feedback.
Pretty much the only limitation to added cameras is that they use the MJPEG video compression format, as opposed to MPEG-4.
In the past we have looked for public cameras that were linked to from various places around the web, and included the interesting ones. People have submitted other webcams that have been a little more buried, but still linked directly to from the web.
If you can access it from the web, then we should be able to add it if it is a JPEG or MJPEG stream.
If you have a list of cameras that you would like us to add, you can submit them by either using the form in the app, or by sending us an e-mail at support@skjm.com
Thanks again!
