What motion detection settings do have set? Don’t forget that a high resolution camera will mean more stream data for BI to analyse if it’s trying to detect motion.
CPU running at 100%?

On the driveway/frontdoor cams, no motion detection, only continuous recording and "capture alert image" in the trigger menu.
On the cloned driveway/frontdoor cameras that "feed" the AITool:

Tried changing the algorithms, didn't do much.
Disabled the "cloned" cameras, each uses around 2 - 3% CPU, I assume because they are doing the motion detection vs the main cameras.
If I keep the two cloned cameras hidden or show them on the main screen, it impacts in total around 2% CPU Usage.
Finally, I disabled everything other than the main front door camera (so motion is also off). I then went into that camera and adjusted the bit rate to a max of 256.
So before the camera was using 10% CPU at 6144 bitrate, now it is STILL using 8% at 256 bit rate (the lowest it will go).
Which gets me back to the same spot... something in the camera settings in BI must be causing the spike...but I can't seem to find it.
Tried disabling Webserver...didn't do much at all.

256bit rate ain't so nice either! I think the green smudge is grass 
Surely shouldn't still be using 8% at this bit rate and 15FPS.

Tried every decoder option, did nothing, tried using the NVidia GPU, changed to H265.... nada.
I think I've ruled out a setting in the camera itself (since the bit rates coming through aren't astronomical and even changing the bitrate to the lowest setting barely helps).
I guess I could try another fresh install of Windows...since I'm a pro at it by now and like to hit things with a hammer. But I keep thinking there has to be something in the settings posted above that is causing this.

Hmmm.... tried to set both the Dahua and Hikvision to the same settings on their respective Cam GUIs:
But this is what I get in BI:
The Dahua uses ~2% CPU, when enable the Hikvision uses 6% at that setting.
So that, I think, tells me something is up with the two Hikvision cams. Let me plug in a Dahua 5442 and see what happens as it's 4MP.

BINGO!
See below. I copied the "FrontDoor" camera (the Hikvision 2CD2347G1-LU) settings to create a new camera setting for the Dahua 5442 (which is named "Backyard"). Except that the Dahua is set to 4MP and not 2MP.
But, the Dahua only draws 2-3% CPU at 4MP while the Hik is consuming 6% in 2.1MP mode, and jumps to 9% in 4MP.
Dahua only in 4mp 6144 constant bit rate (2.5% or so CPU Usage for BI)
Hikvision only in 4mp 6144 constant bit rate (9% or so CPU Usage for BI)
So that is quite interesting. CPU usage is 3.6x times what it is for the Dahua camera, same bitrate.
So the question becomes ... why?
Thinking about it some more, when I had my other cameras all hooked up they were all Hikvision DS-2CD2142FWD-IS, and I was hitting such high CPU usage with them on. Unfortunately I sold all of them a couple days ago so can't check one to see how much it consumed.

Yeah, but I can't wrap my head around why that would be. Especially since I copied the Hikvision BI Settings to create the Dahua, so it's not like there is a setting difference in BI, and if BI is "seeing" ~61 MP/s for both cameras, what could possibly be causing the CPU usage difference??
Holy s&%t...I think I at last found the main culprit!
Saw this in my expanded status screen and never noticed it before. The two Hikvision cameras are outputting significantly higher frames or whatever the number means below via webcast, while the Dahua's were not, even though both have the same settings in the Webcast section.
Disabling webcast on those cameras drops the CPU usage to a strange but lower range of 2 - 6% vs the 9-10% before. I have no idea why the Hik is much more volatile.
Couldn't understand while the Dahua's only showed increasing numbers when I ran the BI android app, but once I turned that app off they stopped webcasting while the Hiks continued. Then I remembered that I had set up a sharptools.io dashboard to send video to a smart tablet in my house, and had it set up for all my Hik cameras but had never set it up for the Dahuas.
Man was that a painful exercise! lol
Now to figure out if in fact I am streaming too high a quality and that can be lowered, or I will just use my Raspberry Pi or something like that to do the streaming direct from the cameras vs using my BI server.

It was fun in a strange way, thanks to you and others that stayed along for the journey and assisted!

screen shot of the item you changed to reduce cpu. was it in BI or was it in the camera ?
I am on the road so have not access to my BI console

That's just it. Wasn't a BI setting at all. I had a tablet that was taking a stream from the BI webserver via a Sharptools.io action tiles sort of interface. So those two cameras were sending a constant mpeg stream and using a ton of CPU while the Dahua was not.
So for now went back to streaming from Tinycam Pro's webserver functionality and via a raspberry pi.
