Bit of a newbie here, so apologies if I'm missing helpful or necessary info. I manually added a Reolink POE Doorbell (via static IP), which is connected to my unmanaged network switch (NVR on same switch). I was able to get my EmpireTech NVR to recognize it and the POE doorbell status is "green", but the doorbell image does not load on the NVR interface live camera view (perpetually spins). It also perpetually spins on DMSS. However, the image does successfully load on the Reolink app. RTSP & HTTP port information match between doorbell & device settings within the NVR. What am I missing?
