Abstract
An anti-theft method to be executed in an active peer, comprising: (a) transmitting radio RF signals to a passive peer to detect whether one of the active peer and the passive peer as a monitored object is in the coverage area of the radio range of the other one of the active peer and the passive peer as a dock; (b) checking whether the monitored object is permitted to leave the dock when detecting that the monitored object is going to leave the area of the dock; (c) sending an alarm signal to an alarm apparatus if the monitored object is not permitted to leave the dock.
Claims19
An anti-theft method to be executed in an active peer, comprising the steps of:
- (a) transmitting radio RF signal to a passive peer to detect whether one of the active peer and the passive peer as a monitored object is in an area covered by radio range of the other one of the active peer and the passive peer as a dock;
- (b) checking whether the monitored object is permitted to leave the dock when detecting that the monitored object is going to leave the area of the dock;
- (c) sending an alarm signal to an alarm apparatus if the monitored object is not permitted to leave the dock.
An anti-theft method to be executed in a surveillance server, comprising the steps of:
- receiving an alarm signal sent from an active peer, the alarm signal indicating that a monitored object leaves an area covered by radio range of a dock without authorization, wherein one of the monitored object and the dock having power supply component acts as the active peer while the other one acts as a passive peer to receive radio RF signals sent from the active peer;
- generating an alarm indication based on the alarm signal.
An active apparatus, comprising:
- means for transmitting radio RF signals to a passive peer, to detect whether one of the active peer and the passive peer as a monitored object is in an area covered by radio range of the other one of the active peer and the passive peer as a dock;
- means for checking whether the monitored object is permitted to leave the dock when detecting that the monitored object is going to leave the area of the dock;
- wherein the transmitting means again sends an alarm signal to a surveillance server if the checking result shows that the monitored object is not permitted to leave the dock.
A surveillance server, comprising:
- means for receiving an alarm signal sent from an active peer, the alarm signal indicating that a monitored object leaves an area covered by radio range of a dock without authorization, wherein one of the monitored object and the dock having power supply component acts as the active peer while the other one acts as a passive peer to receive radio RF signals sent from the active peer;
- means for generating an alarm indication based on the alarm signal.
