I wouldn't do it, myself. I had an i7-3770K (third gen) for quite a while and while it was fine running 4x 4K cameras in H.264 with direct-to-disk recording, substreams for motion analysis and all the usual tweaks, it started bogging down a bit running DeepStack AI, didn't have hardware...
How many instances of DeepStack are you running? You're queueing up ~22 seconds of CPU time in 1,2 seconds so it might be some kind of buffering issue. You have 8 threads so I'd be running 6 instances - one per analysis leaving two threads free.
I have four cameras that all monitor our front yard from different angles with BI simple motion detection triggering CodeProject.AI analysis and sending JPEG alerts via Telegram. All that works well provided I don't mind receiving 4x alerts (ie one per camera) every time someone walks into our...
For a short while I ran 4x 4K 25fps cameras on an old i3-3220 with H.264 direct-to-disk and direct-to-wire (4K main stream; 720p substream) with no issues, and that was with the i3 handling simple motion detection. I can't remember what CPU utilisation was with that chip as I swapped it out for...
Top work on UI3 - Blue Iris wouldn't work for me without it.
Feature requests if I may:
1. Option in 'UI Settings' to auto-switch resolution for tiled and single camera views. Eg allow me to pre-set 720p for tiled view and 4K for single camera view and apply those settings on switching view...
