Optimization an max camera number

[matteopizzoli]

Hi,
i'm running frigate on HA like add on (virtualbox) and i'm migrating in docker (same computer) for use coral on minipcie.
Hp 8200 sff 8Gb 256 ssd disk.
in the VirtualBox i see inference at 130ms in Docker 18ms.
the question is:
inference time increase with number/resolution/FPS or is a parameter that is not influenced by this?
what parameter and relative value i have to see to reach the maximum (and usable) number/resolution/fps of cameras added?
thanks
Matteo

Inference time is not impacted by any of those. Lower inference times are best. Intel NUCs typically see under 10ms inference times.

intel NUC without coral stay under 10 ms??? it's so fast
i woud use more than one pcie coral (it's quite cheap, 21 euros..) but ufortunately i have only one minipcie expansion, by the way i've added 6 camera (720 x 576 detect, full hd clips 4fps) in docker and 2 in VM and everityng work fine (i've not tried with a lot a movement, we are in lockDown :-) )
