Vivotek cameras with OnVif movement detector (not working)

[GiovanniG11 0]

Hi, I moved from Vivotek IP system (Vivotek cameras+Vivotek VMS free software) to a Dahua NVR, there is no possible with any Vivotek model to receive OnVif triggers about movements, it looks Vivotek uses a property protocol to work with its VMS only.
Do you share this? There is any way to trigger Dahua NVR record on movement? Thank you!
