PROBLEM TO BE SOLVED: To provide a security gadget which can appropriately suppress a false report resulting from action of a qualified user.SOLUTION: The security gadget which surveys intrusion to a surveillance object building includes: a sensor which detects the intrusion action to the surveillance object building and performs reporting; an operation part to input cancel operation; a surveillance controller to perform abnormality determination according to reporting of the sensor and cancels the abnormality determination if the cancel operation is input; and a storage unit which stores a predetermined time zone set beforehand. The surveillance controller does not cancel the abnormality determination in the predetermined time zone, particularly the surveillance controller quickly and reliably detects the occurrence of the abnormality, while disabling abnormality canceling and suppressing a false report, since the possibility of false report by the user is low and the possibility of intrusion by a thief is high when hitting the time zone when admission itself is restricted. |
