How much processing power is needed for a camera server? (self.selfhosted)

I was thinking of setting up a home surveilance system using Frigate, and integrating it with Home Assistant. I'd probably have somewhere on the order of 10-15 1080p 30fps cameras. I'm not sure what components I should get for the server, as I am unsure of the actual processing requirements.

EDIT 1: For some extra information, I did find that Frigate has a recommended hardware page.

you could use a lower quality stream (...) for motion detection, then use that to trigger recording on a higher quality stream.

Brilliant idea! Thank you for the suggestion!

If doing CPU-based motion analysis

Whyd do you specifically mention CPU-based motion analysis? Does this idea not work with the Google Coral TPU, for example?

I'm using ZoneMinder on my end with more rudimentary motion detection, hence CPU detection. (My current hardware is pre-IOMMU on the mobo, so no pci passthrough for me...)

That said, if you have hardware that can handle X (via CPU, GPU, TPU, etc), then you gotta decide how you want to spend that. Whether resources are spent more in analysis fps or evaluating higher detail frames is up to what you need.
