Which Dahua NVR's dont have fan inside?

Yes. Dav is very problematic. I will use MP4

Anyone have issues with Dahua Smart Play app? It have problems with dav files. I can't use red bar to jump to another part of the video because it stops playing. Whole Dahua software is really poorly written.

And why Dahua don't support new browser based on Chromium? Who uses IE in 2023?

How to check it? Ping NVR from Windows is blocked (request timeout).

I want best quality. Does 6144 vs 8192 is noticable?

For me this fan is placed wrong because it blow air to the hdd. Hdd don't need fan. It should cool the CPU which is very hot in my opinion. Passive cooling is not efficent in this case.

Thanks I didn't know that. One more question. Can I unplug fan from NVR? Will it run too hot because of this? Where I can check temperature of NVR, HDD, etc.?

Internet Explorer on Windows 7? On Windows 11 I have only edge.

Last question. I can't find. I can't download file through web interface? I don't see any download option or scissors icon. Only way to download is via PSS app? My interface is little poorer than this on the picture...

Will try with lite version tomorrow. I will try to change fps and bitrate also. My NVR is connected to the LAN through Tp-link switch LS105G. Maybe that's the problem.

DMSS playback is ok. Web playback is ok too. Problem is only in PSS. I have only one camera. Substream works ok in PSS. But why it have problems with main H264H CBR 20FPS 8129kbps stream? I have Intel 13th cpu.

Is there any alternative for Smart PSS? I noticed that it stutters on live view. Web live view is ok but SmartPSS stutter for some reason. I don't know why.

I have one more question. If camera is connected by PoE directly to the NVR it does not need LAN connection to record? It directly saves to HDD without router?

I have problem with Live playback. I choose camera and it looks like it want to play substrem by default. I have disabled substrem. How to set default view and parametrs so I don't have to choose camera and mainstream every time?

I disabled https because of problems. I can't view live video with https

Can I still record to microsd card in camera and to NVR at the same time? If my camera changed IP to 10.x.x.x then how to access it from DMSS app?

Problem solved. Blue short Dahua SATA cable was broken. I replaced SATA cable with another from Asus motherboard and it worked. Honestly I didn't expected that new SATA cable could be broken.

That's what I did first. Plugged factory new drive to NVR and nothing. I can't see HDD anywhere in the settings. That's why I tried under Windows. I also tried two other HDD's and NVR only beeps and red led from hdd is light up. I don't know what's wrong. At all I tried 3 hdd's and two sata...

Can I still access camera web interface through NVR? I noticed that NVR changed my camera IP adress to 10.x.x.x from 192.x.x.x

I bought Dahua NVR and it won't see WD Purple 2TB HDD. I initialized and formatted HDD under Windows with NTFS file system and still nothing. What to do?

And NVR have better H265 support than camera? My camera have problems with fluid H265 playback.

Basically I don't want to lost any feature that camera offer. I mean IVS, motion detection, etc. So 5000 series will be ok and even more that what camera can offer?

Hello Which NVR should I buy for IPC-HFW3549T1 camera?

Did you managed it? How to install MCU file?

How to view snapshot saved on SMB server in web interface? In playback section I can only view content on sdcard. There's no SMB option.
