You should release an app for Synology or at least Synology should hire you to improve 'Photos'
It works fine at facial recognition for photos but it doesn't even try with videos, any meta data would be useful for hundreds of hours of family videos.
A terabyte of audio and video is only as useful as the time and date we've organised for, and imagine actual usable face ,object recognition for both media types.
Would this work offline for lowend hardware? E.g. Synology 920+
