I don't think the model of the NVR matters. Safari is currently the only "supported" browser for MacOS. For me the Hikvision plugin for Safari works once, for awhile, then takes a dump until I restart the Mac. Oddly, it will work, for awhile, for other users on the same machine. I've experimented with all the older plugin versions with no joy. They've been promising a specific fix for Safari for awhile. At this point I think running within a windows VM might be my only solution but, crap! Now my Hikvision Stockholm Syndrome will show it's head here - "At least I can still adjust the settings on the cameras, thank you Hikvision! (But what if they break that too?...)".
