Dahua Live feed skipping, stuttering

[trust120]

Hello, sorry if my problem was discussed earlier. I couldn't find anything similiar to my case.
I'm using Dahua 2108-S3 NVR and IP POE Camera - Dahua ipc-hdw2849tm-s-il-0280b. When im watching live feed on DMSS app using P2P the live stream is skipping, stuttering every 2-3 seconds. There is no problem with recordings, only live stream is lagging. If i add camera via local network the problem is not exist. Live stream is clear with no skipping stuttering. I need to have a remove access so i've enabled P2P and using it in mobile application.

Could this be a problem with my home internet connection? Should I additionally configure the NVR to eliminate the problem? There was no such a problem with the previous reolink recorder and POE camera.

Thank you in advance for your tips.

Try the following settings and see if there's any improvement:

• Encoding strategy: General (or Smart Codec: Off)
• Encode mode: H264
• Bitrate type: CBR
• Bit rate: 8192
• Frame rate: 15 FPS
• Frame interval (iFrame): 15

ok, i will try to make those changes. Do the frame interval shouldn't be minimum twice greater than frame rate?

Let's try "equal" initially.
BTW, 8MP @ 30FPS is right at the max decoding capability specs for that NVR.

yeah but im using 20 FPS, so it shouldn't be an issue?

It should not but......

the problem is with the live preview on P2P mode, recordings and local preview is working great, so i guess it's not a decoding capability. Hmm.

Also, try disabling/deactivating WDR.

Sound like network bandwidth issue, not NVR bandwidth.

where do i find this setting?

P2P connections are using UDP protocol to encapsulate Dahua private protocol and works exactly as form of VPN.
As each VPN, they are very dependent on the quality of the connection - especially delays and IP packet resends..

If you have problems with connection, use secondary stream with small bandwidth usage..

In the camera.

I'm thinking it's network issues, though.
If settings in post #2 alone don't help, also lower resolution / use sub stream to see if improves.

It’s a network bandwidth issue. P2P can be like that from time to time.
