FIELD : engineering of systems for centralized protection of vehicles and real estate property objects.SUBSTANCE : inside protected property objects stationary alarm signaling complexes are set up. In each of them alarm alerters are included, connected by means of loop lines to receipt-control device, to which radio-channeled terminal stationary device is connected, made with possible transmission of messages along radio-relay network, stationary cell communication network transmitter, made with possible transmission of messages along standard cell communication network, and terminal phone device. Also present is radio-receiving device. At vehicles parked near protected buildings, mobile alarm signaling complexes are set up. Each of them has alarm alerters, connected to controller, which is connected to mobile terminal device, made with possible transmission of messages along radio-relay network, to mobile cell communication network transmitter, made with possible relay of messages along standard cell communication network, and to satellite navigation block. Also present is radio relay device, made with possible transmission at high-frequency bearing of messages about changes of status of mobile alarm complex to radio-receiving device of stationary alarm signaling complex. Center for accumulation and processing of information has serially connected cell communication network receiver, made with possible receipt of messages along standard cell communication network, and terminal control panel device, made with possible receipt of messages from radio-relay network and transmission of received messages to centralized observation station. The latter includes information input adapter, information processing central microprocessor unit and block for storing map of the area. Central microprocessor unit processes cartographic information and displays on area map the position of vehicle parked near protected building. Thus, invention makes it possible to extend the class of protected objects by including vehicles parked bear protected buildings in aforementioned class. In case of hijacking of vehicle aforementioned system provides monitoring and information support of interception operation on city territory scale.EFFECT : increased efficiency, expanded functional capabilities.2 cl, 5 dwg
