I've changed my 4mp hikvisons to 5mp Swann cameras and now the cpu is on 98%. I have 7 cameras. 8gb ram i7990 Intel. Any ideas. I've ordered 32gb of ram.

I've ticked the intel option on hardware acceleration and it's gone to 12% now! Bonus. Thank you.

Ok I now have the cameras dropping connection and no signal. If I go for no he acceleration it works fine. That's annoying I was hoping it would lower the cpu. Any thoughts?

hardware acceleration would not cause drops and it would not drop 98% cpu to 12. What other changes did you make? h.265 is not supported with intel HA, so BI will change it back

They are in h265. Am I better to use HA and h265 or 264 and no HA

Are these new camera profiles? I assume you turned off overlays and selected direct to disk?

Also what was your cpu load prior to the change?

Just for comparison, I have 14 cameras ranging from 1 to 5 MP on an I7-8700 and am sitting at about 14% cpu.

I know this is an older post, but I am thinking about a Blue Iris set up (vs. nvr) and am wondering what typically causes the most cpu usage. Number of cameras aside, is it the act of recording 24/7 at a given bitrate or the motion detection or something else or all of the above?

I seem to remember reading somewhere (been so much info I have been looking through) that if you have Blue Iris do the motion detection, that can be pretty demanding? But, at this point, I could be misremembering.

in the op's case its an outdated slow cpu with no hardware acceleration as well as setup errors.
All that matters to BI is the megapxiel per second, which is frame rates x megapixels.
if you dont have BI do motion detection you can use the limit decoding option to use very little cpu. See wiki. Even without this function, most high cpu usage is user setup error.
