Method and system for operating electrical consumers in a building

摘要

A method and a system are provided for switching at least one electrical consumer in a building comprising an elevator system. The switched electrical consumer is, for example, a camera. The camera is activated if when using the elevator system the user does not actuate a building door within an ascertained route time, i.e. the user does not arrive at his/her destination. It is possible using an image recorded by the camera to establish whether the user is possibly in a dangerous situation.
