To provide an antitheft device capable of suppressing an erroneous notification in repairing while making it difficult for an illegal person to release a notification.SOLUTION: An antitheft device 10 is operated by receiving power supply from a main battery 16 of a vehicle 14, so as to communicate with a server 12 via a main antenna 20. A monitoring section 36 monitors power supply from the main battery 16 and a connection state of the main antenna 20. In accordance with a monitoring result of the monitoring section 36, a notification section 42 receives power supply from a preliminary battery 40 so as to notify the server 12 of an abnormality when power supply from the main battery 16 is interrupted, and notifies the server 12 of an abnormality via a preliminary antenna 32 when the main antenna 20 is not in a connection state. When a notification prohibition instruction is received from an external terminal device 100 for holding key data to prohibit a notification of an abnormality, a control section 44 prohibits a notification of an abnormality by the notification section 42.SELECTED DRAWING: Figure 1

    【課題】不正者による通報解除を困難にしつつ、修理時の誤報を抑制できる盗難防止装置を提供する。【解決手段】車両14の主バッテリ16から電源供給を受けて動作し、主アンテナ20を介してサーバ12と通信する盗難防止装置10において、監視部36は、主バッテリ16からの電源供給と、主アンテナ20の接続状態とを監視する。通報部42は、監視部36の監視結果に応じて、主バッテリ16からの電源供給が遮断した場合、予備バッテリ40から電源供給を受けてサーバ12に異常を通報し、主アンテナ20が非接続の場合、予備アンテナ32を介してサーバ12に異常を通報する。制御部44は、異常の通報を禁止するための鍵データを保持する外部の端末装置100から通報禁止指示を受けた場合、通報部42による異常の通報を禁止する。【選択図】図1
