Throughout captivity, Manny and Richard converse through the television monitor, as if they are looking at each other. The camera, however, is behind Manny, so Richard would only be seeing the back of her head, as she faces the monitor. He wouldn't be looking at her face. Also, when they show Richard at his console, there is no camera facing him, that would be televising his face into the room. The bathroom wall where the camera is hidden is an interior wall, so the camera would be sticking into the room, in order to be shooting into the bathroom.
