SmartPSS and Dahua NVR and 4K IP-Cam

Hi there,

Can I ask for some guidance. I have the following setup:

4 x IPC-HDW5831R-ZE (plugged directly into the NVR)
1 x NVR5208-8P-4KS2

The NVR LAN port is wired into a Unifi Gigabit switch, and I have smartPSS running on my mac-mini which is also hardwired into the same switch. Whenever I open up SmartPSS, and view Live View - the video is incredibly choppy. I appreciate I'm running 4 cameras at full res, but I would still expect a 1GB port to handle this bandwidth.

Any thoughts - is this what others see or have I made an incorrect setting somewhere? I've attached the encode settings, these are the same for all 4 cameras.

I’m sure others will chime in but in the meantime I’d try to drop the resolution first and see if anything changes. If no change I’d try disabling smart codec but I think dropping the resolution down might stop it. Perhaps your computer can’t handle 4 steams with that high resolution.

What's the Mac showing for CPU usage? For decompressing H.265, that's probably putting a load on it. It would expect processor to be a resource constraint before the network.

You also might consider using VBR instead of CBR. These level of cameras are good at quickly ramping up when the motion in the scene requires it. This can significantly drop the bitrate being thrown at the Mac when there isn't a lot of activity going on.

Thanks. Smart codec cannot be enabled on the other channels. This is the only setting that is different from the other channels, it seems to only allow SmartCodec on D1.

I really want to retain the resolution, I bought them because I wanted to have this res on the recordings and live view. But the level of lag/shudder is too poor.

The CPU does ramp up heavily. I will try and switch to VBR and see if that improves things.

Thanks for the responses all. I have shifted down to H.264H encoding, as well as moving to VBR from CBR. The stuttering has improved a lot, and CPU load is reduced. It's still not 'smooth' video - but is enough for our needs right now. thanks again.
