Applies to: All Reolink PoE cameras and PoE NVRs.
The Answer is yes. But we don't recommend to connect in this way. If you have to connect in this way because of the inconvenience to hook multiple wires in the scenes like between two buildings, please make sure do not add more than three cameras into the POE switch and then attach the switch into the PoE port on the NVR.
If you added more than 3 cameras on the one PoE switch and connect the switch to the PoE port on the NVR, the video stream may be delay or freeze.
