Yes I had lags directly at the NVR when watching with a monitor even @15/1000Kbps. Camera loads were between 250-750Kbps. 2000Kbps maximum when set at H.265, 1080p, VBR, 20FPS, 2000Kbps. I tried powering the cameras with a PSU and connect them to the NVR switch, just to exclude a PoE management...
Yes I tried 264 with as low as 15fps, 1000kbps. I didnt try Smart codec because I read somewhere it was problematic.
I will try adding one camera at a time, but it would be really interesting to read system loads on the NVR and learn what is overloading, CPU, network, whatever.
I have a Dahua NVR4208-8P-4KS2 and 4 Honewell H2W2PER3 cameras plugged on its PoE ports. The NVR connects to a 100Mbps switch where I have two computers that show two cameras each on two FHD monitors. Video is continuous, no motion detection. I have tried all possible settings, but my favorite...
