which way to best implement motion sensing and facial recognition?

[AnduriI]

Hey there,

this forum has been a huge help for me the plan and build my magic mirror. It will have indirect lighting included and needs a way to switch that on.
I planned to do this controlled by motion. I found the various modules here, but don’t know which is best to use. I also plan to use @paviro’s MMM-Facial-Recognition and read that some are not compatible and block the cam. Is there any motion detection module that uses camera and is compatible with the facial module?
If not I might use a PIR, but that’s only the worst case (I don’t like the hole in the front, maybe I mount it below the frame and adjust sensitivity to trigger with moving feet…).
