Hi all,

So I had everything working fine on my setup, although after various updates (physical and firmware), my cameras started triggering on motion instead of triplines. Well I got that all fixed, and during some research on camera settings, I read a post of someone stating to put the encoding at h.264, FR of 15 fps, with a matching iFrame, max out the bit rate, CBR, and sub-stream to D1. Well, I did that for all my cameras. The next morning, I went to check a few things on the NVR, and noticed that it had just froze. I had to power cycle the NVR to get going again. At that point, I noticed that my LAN IP changed back to 192.168.x.x, when it should have been 10.0.50.x. All is good viewing on the monitor connected to the NVR, although with my DMSS, I get sporadic results. Very rarely will the cameras connect, even thought he app says that the NVR is online. I mostly get a full screen of the Refresh arrows. When it does come through, I can double click on an image to expand it, and when I double-click to go back to multi-view, all the cameras time out again. Oh, and sometimes I get message on each camera that says "Please enter device password" or the Lock Icon, which go away if I refresh the screen. And the times when I can view the cameras, the time stamp also pauses for multiple seconds at a time and suddenly jumps up to 5 seconds ahead, is good for 1-2 seconds and then pauses again. This never happened before I changed camera settings. I also noticed that I am no longer able to remote into the NVR through chrome. Edge and Palemoon work fine. I went to change the cameras back to h.265, but I noticed that they were already set. I found out the H.265 Auto Switch was likely the culprit, and turned that off. I also changed Bit Rate Type back from CBR to VBR (based on another article I read). I even tried switching Stream settings on DMS to Sub-stream, but still the same issues...

I attached some screenshots, and although two of them show that the Bit Rate Type is CBR, I can assure that it is now VBR...

So, my cameras are all run through a 16-port POE switch, with one port going to the LAN port on the NVR, and from one of the ports of the NVR to my router. All cameras are static IP. I would say that I am in bridge mode because my LAN is 10.0.50.x and all the cameras are on 10.1.1.x, although I have never been able to find the Bridge Mode button that I see on other posts.

Hardware
NVR = NVR5216-16P-4KS2
Cameras = (11 @ 2MP & 2 @ 4MP) ALL Dahua through Andy, except for an Amcrest IP2M-841B Nanny Cam
Internet = 350Mb down and 25Mb up

I hope someone has an idea of what might be happening...

Thanks,

Mike

Your post is very chaotic one..

1. does NVR over HDMI shows video feed from all cams on main page? if yes, on cams side is everything ok... if not, then start with description what works on NVR and what no...

2. if NVR changed ip address, go (using HDMI/mouse) to network settings and correct ip address to proper one.. then You should be able to connect to NVR using web browsers and old IP..

Also check You computer and router, does both are in 10.0.50.xxx class (the same class as NVR)?

3. if you corrected ip and can connected with web browser, check are the all functions over web browser works correctly? if not, describe what works wrong..

4. if you have full working NVR and web browser, then You can try repair DMSS.. the simplest solution is to delete your actual configuration (NVR device from DMSS) and add it one more time two times:
  • by IP/domain address - and put here NVR ip address,
  • by scan option - where You can scan (or enter manually) NVR serial number - to connect over P2P (which must be enabled in NVR in network options)...

The first configuration will only work in Your local network, but it should working more stable and connect faster.
Second NVR configuration is for use outside Your network.

Check how both configurations works with NVR..

PS. if something is not working, try to describe one thing at once.. not all Your history of problems from past at once..

So you have the POE switch connected to a POE port on the NVR and to the NVR's LAN port?

IF he's actually in bridge mode, all of the PoE ports become like normal switch ports, the NVR becomes essentially a normal switch

Other than his network mess, it sounds like he has overloaded his NVR (not sure model#?) which is why he's having stuttering, skipping, blank screens etc. and having to run such horrible low bad video settings.

Another note for the OP- you should NOT make those setting changes on the NVR, make them on the cameras themselves

  • I also noticed that I am no longer able to remote into the NVR through chrome. Edge and Palemoon work fine. << Yep thats how they work after you "upgraded them"
  • All is good viewing on the monitor connected to the NVR, although with my DMSS, I get sporadic results. <<< So its a networking issue

Sorry about that... :) I also included screenshot of other screens just to show that things like sub-scream were active, what all the bitrates and other settings of cameras were, and anything else I thought might help.

1. does NVR over HDMI shows video feed from all cams on main page? if yes, on cams side is everything ok... is not, then start with description what works on NVR and what no...
Yes, everything on this end shows correctly.

2. if NVR changed ip address, go (using HDMI/mouse) to network settings and correct ip address to proper one.. then You should be able to connect to NVR using web browsers and old IP..
I had already fixed this issue. Just mentioned it as an anomaly... All browsers connect except for Chrome (all of a sudden)...

Also check You computer and router, does both are in 10.0.50.xxx class (the same class as NVR)?
NVR is on a separate VLAN. My main VLAN has access to all others. None of this changed...

3. if you corrected ip and can connected with web browser, check are the all functions over web browser works correctly? if not, describe what works wrong..
As long as it isn't Chrome, I can connect. I haven't verified any of the functionality though... I can check when I get home.

4. if you have full working NVR and web browser, then You can try repair DMSS.. the simplest solution is to delete your actual configuration (NVR device from DMSS) and add it one more time two times:
  • by IP/domain address - and put here NVR ip address,
  • by scan option - where You can scan (or enter manually) NVR serial number - to connect over P2P (which must be enabled in NVR in network options)...
I actually thought about doing this, just hadn't yet. And now that you mention it, I think I do remember turning off the P2P switch in the interface, don't ask me why... LOL If I did do that, why would it still even work at all outside of network? As stated, it may load one time, but any refresh of the screen, and everything just times out. And if I try again later, it may or may not load again, but if so, only once.

The first configuration will only work in Your local network, but it should working more stable and connect faster.
Second NVR configuration is for use outside Your network.
Second NVR configuration is the way that I use... Now to make sure I turned that P2P switch back on... :)

Check how both configurations works with NVR..

I will update...

NVR Model is NVR5216-16P-4KS2
As for overloading, it shows that I have plenty of bandwidth available, assuming I am reading this correctly...

The stuttering/skipping is only on DMSS, when it works. It ran fine before this latest issue.
All camera settings are made in the camera using a web browser. I notice that sometimes the NVR doesn't properly reflect the actual settings of the camera, which may be why some screenshot show CBR rather than VBR.

And you mention "...and having to run such horrible low bad video settings." What are the horrible settings?

Perhaps with all using 2048 bitrate and H.265 but you are severely sacrificing video quality. I run my substreams at 1024-2048

It is impossible for this to work.
Probably it is in reverse (LAN port on NVR to router and one of the POE ports on NVR to dedicated for cams POE switch, where are only cams connected, nothing more).

I will have to verify this when I get home. I may be mistaken... It wouldn't be the first time... ;)

I have done a lot of reading/videos and created a reading list of different settings, but still need to go through them more. I notice that a lot of people have different theories, and that's where it gets confusing...
 
Its not a theory that 1024-2048 is compromising video quality on 2MP and 4MP cameras. Its kinda fact. But if it's adequate for your use thats all that matters

What model NVR do you have?

It is not adequate, although I am still learning...

I run the same NVR at home (actually the newer model with an “e” At the end.)

I run 10 cameras currently

8 - 4MP at 10240, 30fps, CBR, h.264.h
2- 4K cams at 16386, 30fps, CBR, h.264.h
All substreams are 1024-2048

With mostly 2MP cams, no reason you couldn’t run them at 8192, 30fps, CBR, h.264h
Yes many here who run BI will tell you that you only need 15fps which is sorta true, but if you CAN run 30fps why wouldnt you?

NVR's won't always handle max bitrate on all cams. it may be unable to stream all the bits/bytes. You probably need to reduce the data stream from the cams to regain control of the NVR. and then troubleshoot from there.
or possibly something your network is a choke point.

Thank you! I will give those settings a try. I realize it affects recording retention, but I am usually good with a week. I see that you are using h.264h rather than h.265; Is this just for better quality and your hardware will handle it? Kind of like your last sentence "but if you can... why wouldn't you?"
