Cameras slow when plugged into Dahua NVR switch

[mephisto_uk]

I have a very weird situation where cameras plugged into the dahua NVR switch are sort of skipping frames or is slowing down and then is speeding up when doing life view but when I plug the same cameras a normal network switch and then connect that switch to the NVR everything behaves as it should. It is very weird and I have tried different ports on the NVR, different settings on the camera and it's still I can always see the video accelerating a bit and sometimes it's slowing down and sometimes skipping frames. Has anyone experienced this before?

Based on the TOTAL camera megapixels (resolution) you're attempting to connect, are you right at or exceeding the NVR's rated total bandwidth ?

Yes. I have experienced this. So now all my cams are off the NVR. I run BI and an NVR. logging into the cams while attached to the NVR direct was slow as f.
