Look in the BI help file.
In terms of recording, in each camera on the record tab select "continuous and triggered". That records sub streams until the camera is triggered then the recording switches to main stream.
In terms of display, on a multi camera view BI uses the sub streams, assuming sub streams are available, but will switch to the main stream for a single camera view. If full streams were used in multi camera views there would be no reduction in CPU utilization and, therefor, no reason to use sub streams.

Thanks, I will give that a shot. I`m tryin to get my deepstack dialed in. I`m using the CPU version on an 11th gen i5 1145g7, 64gb ddr4 ram, 1tb NVME boot drive, 1tb mpcie ssd, and a 6TB WD NAS drive.

You may have trouble writing a lot of video streams to your NAS. Not all of them are "created equal" and don't have enough cache to handle multiple streams. YMMV depending on resolutions, frame rates, bit rates and how many triggers happen simultaneously.

I meant 6TB nas disk not a NAS itself

OK. Just be aware that video is constant write process with only occasional reads . That can effect the life expectancy of non surveillance drives, unless their "enterprise" level drives.

its and enterprise drive, needs to be replaced soon too. wierd i have 8 cameras, all 4k dahuas at 15 fps, BI is doing the motion and my CPU is only peaking 30%

Is that 30% with sub streams enabled? I'm running 21, mix of 2MP and 4MP, and the CPU is normally at 20% or less. What does the BI status page show for total throughput down on the bottom right, lightning bolt graph icon on the upper left top bar of the BI console?

8800Kbps 72.7MPS
Weird because i ave my cameras all on CBR a they highest bitrate

I'm over double that, ~16000Kb/s and ~160M/Ps. Are you recording in bvr and not re-encoding?

yes BVR, i thought i had everything maxxeed

Optimizing Blue Iris's CPU Usage
Blue Iris uses a lot of CPU time. In most Blue Iris installations, your CPU is the limiting factor which determines how many cameras you can have. As such, it is extremely important to optimize your configuration to ensure you can get the most out of your system while consuming the least...
