Real time facial privacy masking

[railcam]

Good afternoon. has anyone come across a Dahua camera that is capable of carrying out realtime facial mozaic masking for privacy of subjects in view? I found a page on the Dahua site that discusses this but clicking on the camera models indicated at the bottom of the page there is no mention of this feature on individual cameras.
