ANTI-THEFT METHOD AND APPARATUS WITH WIRELESS TECHNOLOGIES
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.
1 . 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.
2 . The anti-theft method according to claim 1 , wherein the alarm apparatus is a surveillance server and the surveillance server receives the alarm signal in wire or wireless way.
3 . The anti-theft method according to claim 2 , wherein step (a) further comprises:
reporting the detected information about whether the monitored object is in the area of the dock to the surveillance server.
4 . The anti-theft method according to claim 2 , further comprising the step of:
receiving information inputted by an user that the monitored object is permitted to leave the dock;
sending the inputted information to the surveillance server;
receiving response information from the surveillance server about whether the monitored object is permitted to leave the dock, the response information being obtained from determination of the surveillance server based on the inputted information.
5 . The anti-theft method according to claim 4 , wherein the inputted information includes user ID and/or password.
6 . The anti-theft method according to claim 4 , wherein the user inputs the information via a smart card or keyboard.
7 . The anti-theft method according to claim 1 , wherein at the step (a), the active peer sends radio RF signals periodically, to detect whether the monitored object is in the area of the dock.
8 . The anti-theft method according to claim 1 , wherein if the monitored object is the active peer, further comprising the step of:
detecting whether the monitored object is moved;
starting operation of step (a) when detecting the monitored object is moved.
9 . 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.
10 . The anti-theft method according to claim 9 , further comprising the step of:
receiving information sent from the active peer about that the monitored object is permitted to leave the dock, the information being inputted to the active peer by a user via a smart card or keyboard;
determining whether the user is an authorized one based on the information; sending determination result to the active peer.
11 . The anti-theft method according to claim 10 , further comprising the step of:
displaying related information about that the monitored object is currently being used, based on the information about that the monitored object is permitted to leave the dock.
12 . The anti-theft method according to claim 9 , further comprising the step of:
receiving detection report sent from the active peer, the detection report being obtained from the active peer by detecting whether the monitored object is in the area of the dock.
13 . The anti-theft method according to claim 12 , further comprising the step of:
displaying current location of the monitored object based on the detection report.
14 . The anti-theft method according to claim 12 , further comprising the steps of:
detecting whether the detection report is received every predefined time period;
generating an alarm indication if the detection report is not received within a predefined time period.
15 . The anti-theft method according to claim 14 , further comprising the step of:
sending a control signal based on the alarm indication, the control signal used for controlling an alarming apparatus near the dock to issue alarms.
16 . 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.
17 . The active apparatus according to claim 16 , further comprising:
means for receiving information of user ID and/or password inputted by a user;
the receiving means again receives response information from the surveillance server after the transmitting unit sends the information inputted by the user to the surveillance server;
wherein the response information is determined by the surveillance server whether the monitored object is permitted to leave the dock based on the information inputted by the user.
18 . 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.
19 . The surveillance server according to claim 18 , further comprising:
means for determining whether the monitored object is permitted to leave the dock, based on the information when the receiving means receives information of user ID and/or password from the active peer;
means for sending the determination result to the active peer.
