NVR RLN16-410 with separate POE network switch

[Guest]

I am looking to create a system using a separate network switch for 3 of the cameras that have longer runs. The attached picture is what I am thinking. Can this model NVR be used with a network switch for 3 of the 8 cameras? Will the NVR be able to see/connect and record the 3 cameras on the separate switch? Thank you in advance.

In your picture, there is only one mistake:
You should connect the PoE switch to the router, rather than to the back of NVR.

Thank You, what is the reasoning or technical reason for plugging into the router vs the NVR?

The LAN ports on the RLN are behind a router and NAT internal to the RLN box. DHCP is provided putting all RLN LAN devices in the 172.16.25.x subnet. DHCP IP addresses will only be provided to devices that have a Reolink MAC vendor ID. There is no IP connectivity from one LAN port to another LAN port on the RLN. You can see it's a very non-standard configuration from what you would normally expect to see. I'm not sure why they did it this way, but it really limits what you can do with the RLN LAN ports other than hooking up Reolink cameras.
