Frigate HW accelerator recommendations for QNAP TS473A NAS for PCIe slot

Hello everyone,

I have HA running in VM on a QNAP TS473A with 64 GB RAM (actually 20 GB for HA). I would like to run frigate with running object (=person) detection for

  • 3 Cameras in the beginning
  • 12 cameras in a later stage

Frigate lists some accelerators, but does not recommend Coral TPUs for new set-ups.
Both M.2 slots are occupied with SSDs, so onle the PCIe slot is left free for an accelerator.

What hardware would you recommend?
Or is there upcoming hardware, which is worth waiting for?

Best wishes
