The invention relates to a method in a theft detection unit wherein the unit is secured to a movable object. The method repeatedly receives acceleration data from a three axes acceleration sensor (4), determines a reference orientation of the three axes acceleration sensor from the acceleration data, determines a difference signal representing a change in angle of the received acceleration data with respect to the reference orientation; and generates a control signal for activating an alarm when the difference signal exceeds a first threshold value for a predefined period of time. The method is very suitable for an object that rolls repeatedly from one side to the other without generating a false alarm due to said regular movement.
