Hi bcre3306,
You need to find info on the rtsp feed and ONVIF settings. Once you find those you can test with VLC. If that works you can then use the info you got to connect with the Dahua OEM NVR.
Do you have any info if the camera meets an ONVIF profile?
Any info on an rtsp feed from the camera?
fyi - for those following:
The C6C (ez360) delivers a 360° horizontal field of view with smart tracking.
