I once worked in a child care center, and the center had video cameras pointed at staff in more ways than I can count. Even when a staff member took a child to the potty, the bathroom door had to be left completely open so the cameras could pick up on how the child was being helped, or touched, or not touched, etc., to prevent any incidences of child abuse in their center. Marvelous idea, I think, because some children aren't that mature when it comes to what "healthy touching" is by a staff member, and "unhealthy touching", so having them on camera is a much better means of being able to tell how a child was "managed" in the potty room.
