I read the title as “NVR hardware for a frigate” and was like WTF kind of self-hosting are you doing with military hardware on a warship.

Now I kind of want a warship.

I just run it on an old mini-pc that had a free pcie slot for a Google Coral chip

About 5 cameras, nothing crazy.

And yes I use it with home assistant as well

The hardware isn’t super important if you can get a Google Coral TPU. You can run Frigate on a Raspberry Pi that way. Without the TPU, it can be fairly CPU intensive.

I run Frigate on an old laptop and before the TPU it would run really hot. After it runs much cooler.

I found a used HP business small form factor i5 6th or 7th gen intel for very cheap, slapped a few SATA drives in the thing, and one of the M.2 Coral TPUs.

it is running 20-30% CPU load with 6 cameras on it - but they standard HD - I pumped one at 4k, and it loaded up much higher, so I scaled back to all 1080p or less. The TPU doesn’t even hit 1% from what i’ve seen. I should probably load a better TFLite model. Nothing mission critical - mostly a novelty.

not the most power efficient setup.

I have 4 ethernet cameras feeding into Frigate inside HAOS. HAOS is running in a Proxmox VM with 4 cores, 4GB RAM, 128GB storage and an m.2 Coral TPU passed through.

The host machine is a Lenovo m910q with an i7-6700T processor that pulls about 35w, 32GB RAM and 1 TB NVMe.

Frigate is set to retain clips for 5 days, after which they are deleted. I have a Samba Backup job that runs every night and retains 10 days of backups.

With this setup, disk space never exceeds 50%, and CPU usage never exceeds 35%.
