Can I Add a PoE Switch Between the Reolink PoE Cameras and Reolink NVRs

The answer is YES.

Applies to: All Reolink PoE cameras and NVRs

But the connection in this way is not recommended for RLN8-410 and RLN16-410. If we have to connect in this way because of the inconvenience to hook multiple wires in the scenes like between two buildings, please make sure we connect 8 cameras at most into the PoE switch and then attach the switch to the Reolink PoE NVR.

Note: For RLN36, you can connect 4 PoE switches, and you can connect 36 cameras in total. However, to avoid the overload of the switch, do not connect all cameras to one switch.
