[NVR Linux based] Can't control PTZ after adding my ONVIF device to the NVR

I can't control PTZ after adding my ONVIF device to the NVR, what can I do?

 

VIVOTEK NVR's  start supporting ONVIF PTZ capabilities after firmware version 2.2.0.X that was released on February, 2017. If you want to use the ONVIF PTZ capabilities in your NVR be sure to upgrade your device to firmware version 2.2 or above.
