Agree. If you never have any plans on using any CVI cams I would also recommend an NVR. I was simply stating that given the two models the OP asked about, that XVR was more capable.
For a comparable NVR look at the 5000 series
Pro Series

For information
So, at the end there is a big difference, i received the XVR and even if it's accept ipcam, i lost some function, like IVS ( tripwire), i have configured it on the camera and it's work with my NVR4104
But when i use the XVR all camera function don't import on the XVR and all IVS notification on DMSS don't work, i can use mvt detection only because of it's the only function XVR accept for IPCAM
All function are really lock on COAX cam and IPCAM only accept for basic usage but the XVR change some configuration ( or impact notification configuration)
Other problem
i can't see multiple Views if it's IP CAM, i see only on fullscreen for 1 ip cam
I see the green camera Icon on the little view but it's stay black until i put on fullscreen ( 1 view full screen)
So, i think for ip cam, we really need NVR
I know i can configure all ipcam on DMSS for notification but when i launch notification i won't have the event record (only the event notification) because of stockage ( on the XVR) ?
I think i will buy the NVR in one or two month
But the NVR record only one ipcam with 4k resolution ( i have 2 ipcam 8MP) and the rest only in 1080p... Bad but no choice...
Sorry for my english
For information i have an NVR4104-4ks2
