I've been debating if I should move my frigate off an aging Unraid server to spare mini PC with Proxmox. The mini has a N97 with 16gb ram. How cameras do you have in your frigate instance on that N97? Just wondering if a N97 is capable of handling 4+ cameras. I do have a Coral TPU for inference & detection.

I have around 6 cameras, mostly 1080p, and about 8 GB RAM and 3 cores on the VM (plus Coral USB and Intel VAAPI). CPU usage is about 30 - 70% depending on how much activity there is. I also have other VMs on the machine running container services and misc stuff.

There are some camera stability issues which are probably WiFi related (2.4 GHz is overloaded) and Frigate also has its own issues (e.g. with detecting static objects as moving) but generally I’m happy with it. If I optimize my setup some more I could probably get it to a < 50% utilization.

Perfect thanks. I'll give the N97 a go and put it to good use as a dedicated frigate NVR box. It certainly has a much lower power draw than my Unraid server.

I'm running thingino cameras off wifi and the stability is kinda meh... Want to try a wired setup with a PoE USB Ethernet adapter...

My Thingino camera seems to have some RTSP issues, which is a shame because I’d like to use it on more devices.

2.4 GHz sucks though. Wish my mesh allowed me to use multiple 2.4 GHz channels concurrently or per node.

I might just succumb and do the prudynt restart by cron every once in a while as this does seemingly fix it.
