Just a quick update on Zoneminder and the kind of processor load you can expect; We seeing, and receiving feedback from customers, that with a modern I7 based Dianemo X86 NC/Core equipped with modern IP based cameras, careful configuration of cameras features/setup and zones (the areas of a video image that are processed for motion detection) its easily possible to run 10-12 cameras in 'modect' mode and only see about 15-20% processor load from ZM.
This is an incredible performance gain over our previous Dianemo X86 12.04LTS Kmotion based installations on the same hardware.
If you have any performance stats you'd like to share for ZM post them here of PM me.
Best
