NVR5208-8P-4KS2E + IPC-T5442T-ZE Buffer problem, recording unusable.

[coolheizer]

I've been running this combination for some time.

I've always pushed the buffering onto the old 1TB hard drive that I still had lying around.

Now I've upgraded to a WD Purple 6TB internal hard drive.

The old hard drive has been thrown out.

The buffering is still there.

I hope someone sees the video and knows straight away what the problem is.
I'm not using the NVR's POE.

Connection plan:
PC, Fritzbox 7490 (Power Mode: 1 Gbit/s), POE Switch (TP-Link TL-SG1005P) 2x IPC-T5442T-ZE+ 1xIPC-T5442TM-AS-3.6

The NVR is connected to the Fritzbox (Power Mode: 1 Gbit/s).

As an experiment, I operated a camera (IPC-T5442T-ZE) directly on the NVR POE, and here too there is the same buffering in the recordings.

I'm simply attaching a few photos of the settings on the NVR and the camera, maybe there's an error somewhere?

If there is something missing I will gladly take more pictures.

Disable SMD...
Use only IVS...
doubling the same events (SMD + IVS) creates a lots of problems...

and if for some crazy reason You need SMD & IVS, enable in storage->schedule storing General + Motion + Inteligent/IVS... Like...

ps check in MAINTAIN menu S.M.A.R.T reports for disks.. does they have high read / seek error rate?

Looks like the problem is caused by not using a fully compatible web browser. Internet Explorer is ideal or Edge in IE mode.

Actually I think there's something else to it.
My 16P (same NVR) does it also. It's not buffering, if you look closer you'll see its actually skipping the IVS recording.
The NVR records the full time Main stream and IVS/MD events as separate files.

I typically set the substream under Record Mode to Manual

I've just set it to Auto and will record for a bit and report back.

use smartpss and check if problem still there, if not its a browser problem.

if you want browser, you need blueiris or frigate.

dahua and hikvision had always bad browser implementation

Its not a problem in SmartPSS nor the playback tab of the NVR itself, nor DMSS.

ONLY happens in that AI Search tab

You are correct. I checked it and its only on AI search. Never used it and for some reason only one cam have this function.

I just confirmed, @duplo and @steve1225 are correct, its a browser issue. Works fine in Edge in IE mode (and I assume native IE), but skips the actual IVS file in plain Edge, Pale Moon and I assume other browsers

MANY thanks for the great article and quick help.

It is actually due to the poor browser support.
It runs smoothly with Edge right from the start, but it keeps crashing during playback.
It's not really a problem though, SmartPSS works great.

I was always annoyed about this supposedly bad hardware from the start, but now I realize that it was just a layer 8 problem.

I noticed that sometimes several recordings were made of the same event, so I have now switched off SMD as suggested.

The NVR records the full time Main stream and IVS/MD events as separate files.

My English is not the best, so I use Google Translate.
There are sometimes translation/communication problems here.

Is my setting now correct? :





I also took screenshots of the other settings, could you please take another look here to see if I can optimize anything?

If there is anything missing, I'll be happy to take more screenshots.
