I have a NVR4216-16P-4KS2 that I like a lot however the live view dosen't do custom split. I was looking at the Pro Series NVR5216-16P-4KS2E and was hoping someone with this model can confirm that it can do custom split. I find the Dahua documentation to be quite confusing. Also can this model remove the white lines around the live view cameras? And how is the smart fan, quiet? Thanks all.
