The invention relates to a method and a device for determining the unauthorized intrusion through a door, the method including the steps: a) determining a movement path of the door as a function of time in all three spatial axes by a receiver and evaluation unit with the aid of a movement sensor (10) in an active mode; b) determining parameters, by the receiver and evaluation unit (12), in all three spatial axes on the basis of the movement path of the door determined by the movement sensor (10) as a function of time, the receiver and evaluation unit (12) determining that an unauthorized intrusion at the door exists when the actual value of the particular parameter is within an assigned parameter range for the unauthorized intrusion, the parameter range being stored in a memory unit (19); c) determining an opening angle of the door using the receiver and evaluation unit with the aid of an angle measuring sensor (11) when an unauthorized intrusion has been determined; and d) comparing the opening angle of the door with a threshold value for a closed door using the receiver and evaluation unit; e) the receiver and evaluation unit (12) determining that the door has been opened when the opening angle exceeds the threshold value for the closed door, and the receiver and evaluation unit (12) outputting an alarm signal if the door has been opened. |
