Hi @Mathyas 

Thanks for posting in our business forum.

When you remove the cameras from the NVR, will the camera still keep the 100% CPU?

That's a way to identify the problem of whether the cameras are to blame.

Make sure your computer is configured with a static IP address and connect it to the NVR and view the CPU settings through the web page.

Usually, the loop is the reason it stays 100% because of the retransmission of the packets and this would eventually take down the network. This is what I want to confirm first before I assume its a firmware issue.

Hi,
Thank you for your answer.

I have removed the cameras, and my computer has always been configured with a static IP address.
However, the NVR CPU is still running at 100%.
What should I do next?

Reset the NVR in the current setup. Will this persist?

Do you have any firmware upgrade to the NVR recently?

Any changes to the network?

Can you record a short video of the device stuck at 100% usage?

This is not a camera or NVR issue!
The Vigi Security Manager is simply faulty! It is still good until v1.6.51, but in later updates it shows 100% CPU usage. I have a TP-Link VIGI NVR1004H-4P with 3 C540 cameras. All device use latest firmware! The CPU usage displayed in VSM is usually: 10-15%.
When I updated to the newer 1.6.71, it immediately became 100%. 15% before update, 100% after update. Joke.
I reported it to support, but they insisted that there was no such thing. Can't be 100% etc. I also tried with later VSM versions 1.6.77, 1.6.85. All show 100%. I didn't even upload the last one (1.6.96), it's unnecessary.
I stay with the older version 1.6.51. Unfortunately, you can only revert to the older version by reinstalling. 

You and I and OP may not be on the same page.

He first reported the NVR instead of the VSM. I double-confirmed several times to make sure it was a problem residing on the NVR instead of the VSM.

I think what you brought up is a different story.

The OP has not yet replied to me. I cannot judge if it is a hardware issue on the NVR which makes it run at 100% or firmware.

VSM is off the topic yet. If you have a problem with the VSM, you may start a new thread and I will check that for you.

Hi,
First of all, I would like to thank everyone for their help!

I reset everything to factory settings and started over. With the up-to-date VSM version, the CPU usage is still constantly at 100%.
I tried Hevesi_J's advice, and with the VSM version 1.6.51, the CPU usage varies between 7-22% with 5 cameras.

Edit:
As part of future development, could it be possible to view the CPU speed through the browser? This way, such issues could be ruled out.

Best regards from Hungary.

• Is the VSM on your computer increasing the CPU usage of your computer to 100% instead of the NVR? This thing.

• Or is VSM in certain software versions increasing the CPU usage of the NVR to 100%?
• Or is it just the NVR itself surging to 100% CPU usage?

It is completely three different topics.

In your original context, it gives a feeling that it is the NVR itself malfunctioned and increased to 100% CPU usage.

I am clueless after reading what J wrote and your last reply. It has not been clearly described until now.
