What ports for RTSP

What port is being used for RTSP? I am trying to add to my nvr. What would the ip address be for the camera?

I’m using Blue Iris and having no luck as well with 554 / 8999

It’s port 554. Are you able to view the stream in VLC?

I had it working on my Blue Iris v4.8. I moved it to a different location that has Blue Iris v3, and it does not work on that version. I am trying to get it to work on a different NVR. I wonder if ONVIF is in the works for another firmware.
