The appliance has one or more microwave sensors (11) fitted on or in a wall (24) of the transport container (30). The sensors, which react to any movement within their detection area (12), are located so that this area lies within the monitored interior (25). The sensors can be located under the floor area of the container, and they can be positioned in rows so that their detection areas abut one another, or overlap, to form a curtain along the outer edges of the floor. They can be arranged only along those outer edges of the floor which are normally accessible from the outside |
