BREAK-IN SENSOR FOR MONITORING AN ENTRANCE TO A BUILDING TO BE MONITORED, AND METHOD

摘要

The present invention relates to a break-in sensor for monitoring an entrance to a building to be monitored, wherein the break-in sensor is arranged on the inside of the building on the entrance, comprising: an acceleration sensor, which is designed to detect motions of the break-in sensor in at least one spatial axis and to output an acceleration signal in the event of a motion in the at least one axis; an environment sensor, which is designed to detect at least one value of at least one physical variable in the environment of the break-in sensor; and a plausibility-checking device, which is designed to check the plausibility of the acceleration signal by means of the detected value of the physical variable and to output a break-in signal in the event of the plausibility check being passed. The present invention further relates to a corresponding method and to an alarm system having a break-in sensor according to the invention.
