Welcome to the Forum, @rcmtncosmo! 
Since you tagged your topic for Web View, I think that’s probably the primary answer, especially if you’re using a subscription and have more than one camera. You also chose a tag for Cam Pan v3, and that’s one of the Cams that currently has the RTSP capability that you can enable and stream locally using various applications, such as VLC media player.
