Hi JiPe and welcome to the forum!
I am happy that you like what you see and I hope we can continue together ;).
Yes, the manufacturers change these things sometimes and it causes some problem for us and the users. In this case they have changed from play1.sdp to live1.sdp. If you only want video and audio it is easy to connect using the Custom URL or ONVIF if the camera support that. But, if you also want the PTZ we need to make a new template since PTZ and video/audio use different communication protocols. I assume you have changed default port 554 to 22222.
The process is to find the URLs for video and audio which is relatively easy since we already have that. The more tricky part is to get the PTZ commands. Hopefully, they are the same as for the DCS-5222L-A1 version. So, I need you to check that. Can you connect the camera using the old version and test if the camera moves when using PTZ. If that works I can combine these commands and add the new URLs and create a new template for NCS. If you cannot check that I need to get access to the camera for some testing.
