Hey Saltser, The H-series line of cams are OEM Hikvision and the R-series is Raysharp. Both work with Dahua NVRs via ONVIF.
I dont have any experience with the HDW5231R-ZE camera, but Nellys has youtube videos on a lot of their current cameras - Nelly's Security
And sometimes its easier to reach out to Nellys directly at [email protected]
I have the R series cams running well on Dahua NVR's, If you mix mash brands don't expect anything other than Video and motion to work if thats all you need.
