You can test 2 things.
-It seems that the camera support the ONVIF standard so when adding the camera use the tab for ONVIF Source. That should also give you PTZ, maybe.
-From the address above rtsp://… it is probably the port number that is missing. So write …201:554/onvif1 test also with onvif2
-Test also with stream type RTSP_UDP
Please, report back which works.
