  • 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’ve tried a few of the things you mention over the years.

    However, I’ve lately gotten into the used business PCs. The performance of even a 6th get Intel CPU more than double an RPI4 or the ATOM in my NAS, depending on how you count. Sure, it’s quite a bit more power, and they have their place (RPI in the garage), but I’ve gotten a few SFFs that have room for multiple HDs for like $50-$60 shipped, as long as i’m patient, since I don’t care for the windows license.

    The CPU benchmark sites are what convinced me that more SBCs was not the solution for me.

    I also tell myself that i’m recycling what could have been ewaste otherwise. I am afraid to calculate the energy cost.
