We have never yet encountered a problem where the capacity of a hard disk is too big for a Hikvision NVR.
e.g. we have 10TB HDDs running in their most basic 7604 NVRs.
We are frequently asked this question because Hikvision's literature states some arbitrary maximum HDD capacity e.g. 4TB.
However, that 'maximum' stated on for instance their datasheets is simply the biggest drive that you could purchase at the time ...
