can you use other cameras with this nvr

I have a few extra cameras they are qcam 2 megapixals they are ONVIF Compliant will these work on this nvr

The NVR will usually work with up to 2 non Reolink cameras I believe. They have to be on the same network as your NVR, they cannot be plugged directly into the NVR from what I undertsand. I only tried this out with one non reolink camera and it worked fine a while back.
