I am currently running 28 4mp and 6mp Dahua cameras setup for substreams and am running between 14% and 17% CPU on an I7-8700 @ 3.2GHz . Amazing. The best upgrade yet, worth the money and then some for yearly licensing.If you are going to run bare metal, and you have 17% GPU with 5 cams, you should be fine with 11 cams. Especially once you enable sub-streams and direct to disk. Having SSDs might help your recording if you are running max resolution and max FPS on all cams.
On initial set up, I DIDN'T check record to disk. Now i want to, is the a box somewhere else in the 3 menus ? or delete cams an start over ?
Actually that may be the wrong thread but it is the right answer.Camera Settings -> Record Tab -> Video File Format and Compression -> Direct to Disk
Wrong thread...
