The short answer
ONVIF can help discover services and profiles; RTSP addresses a media session. Choose the workflow required by the camera without assuming one successful stream provides all controls.
Work through the checks
Write down the exact outcome you need: live observation, a saved event, camera movement or long-term retention. Check each outcome separately instead of treating a visible stream as proof of all functions.
Check the model manual for an ONVIF service switch and any separate ONVIF account. Use the configured service port; do not assume it equals the RTSP port.
Run local ONVIF discovery on the intended adapter. Discovery may not cross routed networks; compare the discovered address with a manual connection to the known camera IP.
Copy the RTSP path from the documentation for the exact product family. Keep the address, service port, channel and main/substream selector as separate values during diagnosis.
What to verify
Verify that the device reports the required ONVIF PTZ capability and that the local account has control permission. Begin with a small supervised movement and confirm the stop response.
