Batch video file analyzer - human/face detection

[simonchello]

Hi.
I am looking for software that can scan/analyze multiple video files and detect which clips contain human motion or face.
There are more than 100 000 clips in .mkv format from my security cameras, but lots of clips are wind or sun/shade triggered (despite object detection, zones and hotspots setup in my security software). Is there a way to find and delete such "blank" clips?

Possibly skin tone detection ? Perhaps an Avisynth wizard will chime in regarding how to do that ! If nothing else, this may be helpful.
