So far so good then. Problem is that audio/video use rtsp and ptz use http. So entering the rtsp will never get you ptz. To get all, the protocols need to be combined in a predefined template. This is a drag so therefore the manufacturers started to develop a standard for devices like IP camera so it should be easy to connect to them from softwares like NCS. Problems is again that it is standard within quotation marks. So ONVIF is the only way to make it all work.
Since you are working with ODM and got the rtsp string you should also be able to find the http onvif URL that should get the different profiles. Go to ODM again and login to the camera and go to
At the red arrow you should have the magic URL. Copy that URL and paste it into where the red arrow is pointing below in NCS
Add username and password and click on Get Profiles. If everything is as I hope you will now have some ONVIF Profiles to select and then select PTZ mode. I recommend to use static IP to make it more stable.
I keep my fingers crossed!!
