I have a second option, what if I buy the same Dahua recorder and use it to read the harddisk from the other recorder? Has anyone tried this?

I've been trying to read video from a dahua harddisk using the Dahua DiskManager program, however, very few of the videos are playable. Trying to read the big mayority of them gives a "Failed to open record ! Please check disk..." But the disk is fine and the recorder was working fine, I...

The problem I think is not anything you describe because: -The DVR and PC use ethernet -I can playback all the 8 cameras' main stream at the same time without issues so I don't think this is a network problem The problem is when viewing on live. As I said, it's been working well until yesterday.

Hi everyone, I have this Dahua DVR I have been using for months with SmartPSS. The PC and the DVR are in the same house network. Suddenly, SmartPSS can't load the main stream for 6 of 8 cameras, only sub stream. When I try to display the main stream, it gets stuck on searching video forever. The...

So today the problem got worse. Now the XVR can't live stream the main stream to smartpss or the ios app (the PC and XVR are connected via ethernet). I even disabled all recordings and this issue is still there. Something is wrong with this device and I will replace it probably this week. I'm...

I understand but, is using a dvr optimized drive so critial that a desktop drive gives these problems? I mean, the bit rate it's writing at is not very high.

It seems that some brands count that time in seconds. So this is the thing: I tried to open the RTSP video with VLC, I opened the VLC menu to see media info and it's already using h265. This means that the video encoding is happening wether or not it's recording, this suggest the problem may be...

The purpose of doing this is not fixing bad sectors, but to see if the xvr says something is wrong with the drive. Also I didn't know there were series of HDD designed for recorders, I thought any good drive would work.

I'm doing a HDD detect now (that function the xvr has to detect bad sectors). It started at 3Mb/s. I disabled all recordings and it's now 185Mb/s.

My SMART shows this: Apparently the HDD is this one.

Thank you for the help :) I'm using the last version of smartpss I downloaded from dahuawiki.com last week. The firmware is version 4.000.0000002.11, built on last august. I will try to disable MD, but if that is the problem, then why does the xvr have so many other functions like face...

I'm afraid I don't know, I didn't install it. However do you think it could be the harddisk? I mean, this xvr is supposed to work with 16 coaxial 1080p@25 cameras, I don't know the required HDD bandwidth for that, but I'm not using 16, only 8 and two of them are inside the house and almost never...

No brand here, just standard coaxial PAL cameras.

I already tried to switch to h264, but I will retry. With network, you mean my internet connection? It's gigabit, but anyway the network is not the problem since I can't even playback on the device itself, using a monitor and a mouse. It gets very laggy and slow when all cameras are recording.

The manual on page 57 says it is the time between reference frames, and it's set to 1s, I'm not sure that's the problem. Edit: I can only choose between 1s and 2s in that menu.

Hi there everyone, I hope you can help me with this problem I have. The story: I have had installed some cameras in my house. The system consists of 8 cameras, all of them AHD 1080p coaxial. I bought a Dahua XVR7116HE-4KL-X and I noticed something strange the day I turned it on, I was unable...
