Ways to reduce CPU when multiple people are logged in?

[Jared]

Hey guys, So i have a system with 41 cameras and it runs around 60% when there is a lot of activity, 45-50 when no one is around. When a couple people are logged on, the CPU jumps up in the 90's and i cant have that. I have 90% of the cameras running at 7 fps and a few running at 10fps. All direct to disk. Just looking for some help hopefully to bring down that 90% drastically, i hope that anyone of 5 people or 5 people can be logged on at the same time viewing the cameras without killing the CPU.

I guess i can bring the 7fps down to 5fps. But any other suggestions would be helpful. Maybe a way to throttle the users back?

Depending on the method of live view being used, (anything that streams H.264 video) you may get some benefit from modifying the 3 encoder profiles under Blue Iris Options > Web server.

Particularly the "Preset" option, "ultrafast" uses the least amount of CPU. I would say to also enable the option to resize the output frame (to something small) but I don't think it has worked in months.

Thanks a lot fenderman. I really do appreciate your help. I will give it a try and let you know.

i did change preset option and it did help quite a bit. Id say it brought it down 8-10%. I think i am going to bring frame rate down to 5fps on most cameras. I want to get that % down as low as i can. 70% and under what im shooting for. Sucks i have to go into the camera settings again. 41 cameras takes a long time. I read that nvidia cards raise cpu also but i needed an hdmi port for my monitor which is 100 foot away from the nvr. Is there a better solution?

Are you using hardware acceleration, and are you sure that it is working?

41 cameras is a lot if they are more than like 1 MP. You may not be able to hardware accelerate more than a certain number of streams without actually increasing usage... I'm not sure.

If you have the Blue Iris GUI open, make sure you limited live preview frame rate to like 1 FPS -- Blue Iris Options > Cameras tab.

I have them all set at 1.2 MP. I do have hardware accelerate checked, however im not sure how to check to see if it is working. Currently i have live preview frame rate set to 5. I will adjust it. One question. If i minimize, or just have it run as service with no GUI open, would that cut down on cpu? Looking at the main monitor is not important 99% of the time. I guess i can just check it out myself, i just downloaded your UI2 yesterday and now i can see the cpu, something i couldnt see before on BI web server page.

You can run as service to reduce CPU usage. Minimized should have a similar effect.

You can know if hardware acceleration is working 2 ways: 1) it should reduce CPU usage. 2) A tool like GPU-Z should show your intel graphics adapter as having some significant usage.

Thanks for you help again. I did limit live preview down to 1 on the main GUI and that cut 20+% off cpu, now im running in the 60 percentile range with 3 people logged on. AWESOME!!!! I will check out the GPU-Z tool later today.
