I'm just running the basics at this point. Dell optiplex 7010 with a Intel Core i7-3770S 3.10GHz. 32 GB ram. Yesterday i snapped a photo showing CPU 27% Mem 2.65 Gb. I havent reduced any of the streams from defaults. I have 6 Cameras running at the moment. 4-5Mp and 2-2Mp. ( but Nightowl is using CPU Clocks also for Windows based viewer from the local DVR. )
Video/jpg's are saving to a WD Blue 5.0 TB. OS( Win 10 64) is on a Samsung Evo 256 GB SSD.
Blue iris is version 5(paid). The original processor was a Core i-3. The i-7 runs a bit warm in this maintenance room with the stock cooler. I have 4inch boiler pipes and domestic hotwater pipes running across the ceiling. Once i saw the temps climbing past 70C-75C, I switched the bios to "fans at full speed", now its hovering around 59-65C.
I think I might like an Optiplex Minitower with more room for a larger fan at some point. Or a maybe a 3rd gen Dell precision MT cooler if it's any bigger.
POE switch is a Cisco WS-C3560X-24P-S Catalyst 24-Port Gigabit PoE+.
Router is a piece of crap a homeowner threw away from Dlink. System is offline. but I can use the Wifi from it to view Nightowl CMS DVR another room on my phone away from the noise and heat.
Also can peek in on status and see what ip addresses are showing up.
Running
cat5e riser cable from Fast Cat on Amazon. terminates nicely, pulls out of the box nicely. Of course having said that, I shoulda looked under my nose first. Menards had Cat5e solid core about 12 bucks cheaper.
doh.
I am not experienced with BI. So I flip switches and turn features on and off, go home and see how it recorded over night, tweak some stuff, read some stuff, crash camera's, ruin working configs, and bumble my way into decent camera setups for now.
