NVR kit vs NVR + standalone cameras (RLC-1212A)

[XeviaN360]

Hi all, i'm trying to understand if there are differences between buying an RLK16-1200B8-A kit and an NVR with standalone Reolink cameras, in terms of functionality and hass integration.

I'd like to buy a reolink nvr (16 channels) and 11 RLC-1212A, but they are not out yet and Reolink doesn't respond to availability questions of that camera.
So, the RLK16-1200B8-A is a brand new kit containing an NVR and some "RLC-1212A like" cams. They are named B1200, and here you can find the specs: https://reolink.com/fr/product/rlk16-1200b8-a/#specifications

Seems that they are RLC-1212A with some features striped out. No sd-card, no autonomous streaming, they do not work without the nvr. This could not be a problem, but i'd like to know if i'll miss some feature or some integration in hass with that kind of kit.

Any ideas? :)
Thanks!

Some doubts: could i get multiple video camera stream from nvr ? Could this be a bottleneck for the nvr, instead of taking the streams froma cameras directly?
Also: does the person/alarm/notifications works with this plugin, having only the nvr to exchange data with?
