BI Slows Down Computer After 1 Hour

[rfj]

When I start BI my system starts responding very sluggishly after about 1h. After a few hours all HikVision and Dahua cameras freeze up (the time embedded by the cams is not updating anymore). Only a couple of cheap wireless cameras are still responding. When I go to the settings of a HikVision or Dahua camera and simply just click ok BI freezes up for a while and then crashes.

The reason I am saying the slowdown is caused by BI is because when I shut down BI the system becomes responsive again. As mentioned, the first 1h or so it work fine. This just happens after some time. Windows task manager doesn't show anything extraordinary. BI takes up about 10% of CPU time (total around 20-50%), approx 2GB of memory (total about 40-50%), 1-10MB/s, 50-60Mbps (total 6-10% network). I do not believe it is the cameras that are being hacked (UPnP is off, cameras are not configured for outside network access).

What could be causing this or where can I look for further clues?

The typical suspects are video driver updates, not helping type updates, and hardware acceleration. Which version of Windows, 10 or 11? What version of Blue Iris? Are you using sub streams? Have you followed the steps in "Optimizing for Blue Iris" in the Wiki? What processor, specifically as in i7-12000K? How much memory is on the system? Are you recording direct to disk? Are you running anything besides Blue Iris on the machine?

Make certain that you have correctly excluded Blue Iris from any antivirus scanning. Including Windows Defender.
See the topic in the Blue Iris help file.

Windows Defender is turned off. Instead, I am using Malwarebytes and in that software I excluded the folder to which BI stores the video clips. Regarding is 24/7. The computer is my regular computer so I do other stuff on it but nothing much. The biggest resource hog is Chrome. But even when I close everything I see that slowdown. I did not have this problem before. In add/remove programs I see that "NVIDIA Graphics Driver 512.15" was installed on 8/6/22. However, despite the work "Driver" that doesn't seem to be the actual driver because when I go to the properties of my GTX 970 (yes, old) it says Driver Versioni 30.0.15.1215, Driver Date 3/17/2022. I also attached a screenshot of the Cameras tab from BI Status. I do see a bunch of "No Signal". I am not sure if that is normal or not. I haven't looked at this much before so I don't have a reference. Is there a way to record those numbers lets say every minute for 24 hours? Then I could check if I suddenly see some big changes.

PC: i7-9700K, 32GBytes, Win10 Pro

You are on an older version of BI where hardware acceleration was ok, but for kicks and grins, go ahead and turn hardware acceleration off at both the global and camera level and see if it levels off.

Windows Defender is turned off. Instead, I am using Malwarebytes and in that software I excluded the folder to which BI stores the video clips.

Then you still don't have everything properly excluded from Malwarebytes. Read the BI help file!
That is most likely the problem.

I did turn off hardware acceleration in the global settings and for all cameras. I also set GPU to 0 for all cameras. After that I restarted BI but this didn't help. Then for Malwarebytes I also added the exe files according to the documentation (see attachment), again restarted BI but unfortunately that didn't help, either.

 

[wittaj]

Did you exclude where the video files are recording to as well?

Do you have any other utility going that may be bogging it down like a disk defragment program or cleanup utility? Maybe as part of malwarebytes?

 

[looney2ns]

You still don't have the database excluded.

After trying a bunch of other things incl. reinstalling BI I got an "approximate" source of the issue. I disconnected my LPR camera from the switch and the issue disappeared. I made my own connector at the camera so I suspected that. I connected the cam to the switch again and then changed the CAT6 coupler with a different brand. Then it worked. I switched the old one back in to see if it is really the coupler but it still worked. So I suspect there was some bad contact. In any case, it is working now. Thanks for all the input.
