I must say that when You doing 10+ cams systems in one day, then NVR interface for camera firmware update / image options / encode options / Smart Plan / IVS / Video Metadata is much faster way to configure everything..
And in case of Dahua and newer Dahua NVR (5xxx-EI) it works...
The only thing which have lacking options are NVR camera settings for image, where manual shutter options & time plan settings are missing..
