As others have stated, this operator needs to be flogged and educated. A computer based video ingestion/playback system with disk storage and a complex filesystem is not a tape deck. You can't can't simply power it off as if it were a tape deck. I would assume based on your description that this is a mobile storage system, often moved from one location to another, probably in a van, and this is why the operator simply hits the power switch?
