How is your network configured? Are your cameras going through the router at any point or are they isolated from the internet with VLAN or dual NIC in the BI computer? If they are going through the router and the cameras are on the same IP address range of your other devices, that is likely the problem.
But even if your cameras are isolated from the internet, for a Xeon processor with 6 cameras at 40% CPU, it is clear you have not done every optimization or you are using the computer for other things, and that will cause the problem as well.
Do
EVERY optimization in the
wiki and you will be sub 10%, but more than likely even sub 5% CPU at idle. Substreams are a must, especially once you get over 4MP cameras.
I am on a 4th generation with way more cameras than you and my idle is 10%. Another member here runs 50 cameras on a 4th generation CPU at 30%.
And by EVERY, I mean
EVERY. Too many people come here complaining of high CPU usage and claim they have done every optimization in the
wiki and once they post screenshots, we see they are not using the substreams and that is probably one of the biggest CPU savers. Do not skip one because you think it isn't important or won't make that big of a deal. Even dropping frame rate a few FPS can make a big difference. No reason to run more than 15FPS, and many us have cams running at 10 to 12 FPS.
If you do not understand what something does in BI, then ask. Too many people also change a setting not realizing what it does and actually makes their performance worse.
Please post a screenshot of your BI camera status page that shows FPS, MP/s, etc. so we can see what is going on. 40% for 6 cameras on that processor is too high.
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...
