  • 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.





  • For what it’s worth, NFS in my experience is also faster. I had a very similar use case (but QNAP instead of Sinology) and switched everything over to NFS and saw performance gain. Little things like previewing IP Camera security footage would feel slow on SMB, but snappier on NFS. I’d gotten over the user thing, but the speed is why I switched.

    I did eventually wipe QNAP’s software in favor of stock Debian – but the prevailing wisdom seems to say Sinology’s OS is pretty good.
