Face recognition and comparison event

[avantcv1-commits]

I have DHI-NVR2116HS-I/L and DHI-VTO2101E-P-S2, on the NVR there is an option to use one channel for face recognition and comparison with the face database. I would like to implement opening the door upon positive recognition and sending a notification about such an event to the phone (possibly with a photo from which the recognition was carried out).

Using curl, I saw an event that corresponds to positive recognition, but unfortunately I do not see this in your integration. If there is an opportunity to implement this in your integration, I will be infinitely grateful.

It would be wonderful if face recognition could be added to the integration. Many Dahua cameras and NVRs already support face detection and recognition events, and exposing them in Home Assistant would greatly expand automation possibilities. I'd like to add my support to this feature request as well.
