NVR16CH-16P-2AI Questions

Your internet speed has nothing to do with your problem.

Using WiFi in any form in the chain for the cams is asking for trouble. Everything should be hard wired with no camera data passing through a router.

It's showing that the link between the router and my laptop has sufficient flow to support the streams, therefor within that same LAN, it's at least that fast.

As stated above, all cams are connected directly to the NVR, and the connection between the NVR and laptop is 1 gigabit, unless I'm on wifi, which is also more than fast enough unless you're suggesting 650 Mbit (~80MB/sec) isn't sufficient bandwidth to stream a 2K feed at an ~8K bitrate. The diagram above shows nothing is passing through the router - unless I'm accessing it via DMSS from outside the house, in which case it is, and it still works fine through DMSS.
 
How many cameras are you running?
 
Change from H265 to H264 and see if the problem is fixed.

H265 is still not a standardized code across all platforms like H264 is and this can cause many problems.

Most here run H264.

H265 storage savings isn't real world.

I switched over to H264H x CBR @ 14K and loaded up 4 streams on the browser and 1 in PSSLite and the network flow came up to ~75 Mbps as it should have. Seems more like the browsers either aren't utilizing sufficient CPU and GPU power to decode these streams or there is another issue, but I don't think it's bandwidth related.

What encode settings do you use for 2K cams? VBR x Quality or CBR x XX Mbps? H264, B, H? SVC Off (1)? I Frame and Smooth Frame?

I tend to only change my encode and camera settings in the camera specific web config pages, not within the NVR since not all attributes are available in there - I feel like I've made changes to a camera setting in the NVR and it changed some other stuff too, so I'm just using those camera pages directly for everything I'm able to. Is that a good practice?

I should mention that the user experience in a web browser was no different after changing codecs, however when using AI search, there are no longer thumbnails for the results...

Most here will use H264 or H264H

For a 4MP camera most will use 8192 bit rate and CBR.

Those with Blue Iris tend to run 15FPS and 15iframes.

Those with NVRs tend to run higher FPS. Many run 30FPS. Just keep in mind movies for the big screen are shot at 24FPS.

Yep, you should make all changes in the camera GUI. Only the alerts and recording should be set within the NVR.

Also make sure codec and FPS match main and sub streams.

I can think of any other settings that would cause this. Maybe give old Internet Explorer a try. It is still baked into Windows.
 
So are you trying to stream Four cameras at Main stream bitrate over wifi?

Lets get this one out of the way

SmartPSS and DMSS are likley pulling the substream
 
OK so here are 4 4MP streams playing on the NVR Web GUI from my laptop over wifi (Netgear 8000)
(Three) at 4MP, 30FPS, 10240 bitrate, H.264.h, CBR, Iframe matches FPS (One at 8192)

This is Edge in Edge mode on a Win 11 laptop

Some slight choppiness but it smoothed out after a few seconds

When you say this

Are you talking about using a web browser to connect to the NVR and using the "LIVE" view page as I did above???

Either wifi or wired, it makes no difference at all. There is more than sufficient bandwidth over either, and the experience isn't changed one way or the other. SmartPSS is pulling main streams at 10000-14000 Kbps as I have them set. It's smooth. The web interface, regardless of browser is clunky, stutters and the playback and live view frame rates are significantly slower than via either SmartPSS or DMSS. I can't say for sure if DMSS is pulling toned down versions of the mainstreams, but I can toggle between "HD" and "SD" and it's a considerable difference. Both work well over wifi.

I've since enabled hardware decoding on SmartPSS, but can't really tell if there is much difference in user experience if any. PSS works pretty good for what it is.

Is your viewable feed actually close to 30 fps though? Mine is set for 30, but through any browser it's much much lower, and there will be pausing and catching up. I see the timestamp on all of your feeds is within 1 second, it's normal for my browser to walk out a few seconds more than that too.

I just finished watching some playback side by side with web browser and PSS, and even with playback of saved video, the browser interface is choppy and the framerate is far lower and not as smooth as in PSS. Additionally, there are substantial user issues with moving the time navigation bar to navigate to different events. It'll go to an unrelated time while playing a selected section and is essentially unusable. It seems like too much for the browser to deal with. Whether this is an AMD exclusive issue, or some sort of problem with my specific computer not providing sufficient hardware resources to the browser, I'm not sure.

Here's an example of how the live stream from Web Browser looks with one feed playing vs the playback in PSS to give an idea of the choppiness. It's often much worse, but moving the mouse cursor around, clicking on other tabs, or opening screens is all about the same experience. Trying to navigate in playback is worse than this appears.

Your feed looks to be smoother than mine. Even Chrome shows the bitrate and has the functions - I have yet to see a difference in experience between Edge, Chrome or Pale Moon. Here's a ~30 second clip of loading up the interface in Edge. It'll give an idea of what it looks like loading up and how smooth and quick (or not) the feeds are.

They are matched to your settings of "4MP, 30FPS, 10240 bitrate, H.264.h, CBR, Iframe matches FPS"

I notice that your time seems to be accurately counting seconds bu the video looks to be sub 10fps very odd

I'm using an older NVR. Is you're relatively new?

I gotta think there's some resource being challenged
 
Can you show a full res clip sample of recorded video/exported at 8-10MBs?

Yes it's a brand new order from Andy. Straight out of the box other than adding the 8TB Skyhawk AI to it and running the cables. All runs are outdoor double jacketed CAT6 with gold plated connectors. I tested each cable run to gigabit rates before connecting them to the cameras. I'm using the default network settings (TCP), other than the assigned gateway and IP for the NVR.

I'm trying! SmartPSSLite isn't so smart. I've pulled up CH1 on Playback and selected the time trim section, and it's in the queue to export, but wont.

It works great once you learn it

Two methods, timeline (more accurate) and pre-indexed clip

I'm doing exactly the same. The blue progress bar doesn't move. It will not proceed with the export. If I click on a bunch of stuff like pause, and start, occasionally it will glitch out and pop up a read fail icon. Then if I click the download button it will download. I did a screen a screen capture of this happening, but the pop-up export window doesn't show in the screen capture.

Is it just me, or is it hit and miss with clicking on and dragging the timeline to move it? Half the time it does not work...

Here's one after many many tries.
