Your phone or tablet will open an app to play the RTSP stream. If your device has more than one app that it thinks is capable of playing the stream it will present a list of apps for your choice. Try each app until you find one that works. If none of the apps on your phone work you will have to go to your app store and search for “RTSP players” until you find one that works.
Desktop Computers, Laptops, iPhones, iPads, and iPods should not have to use these streams. Instead use the Player found on the “Live Stream” page for best results.
