Help adding Reolink TrackMix

I have a URL that works in VLC but I can't seem to find a tutorial on how to add that to my DVR. This is what I'm using: rtsp://admin:[email protected]:554/h264Preview_01_main

I seem to have the basics working. I put my info into this and plugged it into the add source wizard
