Abstract

A method and system for detecting an intruder is provided. The method includes monitoring received signal strength in a wireless router and creating a profile of the received signal strength as monitored during a learn mode. The method includes comparing activity of the received signal strength in the wireless router, during an intruder detection mode, to the profile and issuing a notification, based on the comparing, wherein at least one step of the method is performed by a processor.

First claim

What is claimed is:

1. A method for detecting an intruder, comprising:
monitoring, by an analytics module, received signal strength in a wireless router from wireless devices during a learn mode or a training mode, wherein the learn mode is initiated by the analytics module and the training mode is initiated by a user;
creating a profile of the received signal strength as monitored during the training mode, wherein the profile includes at least one time-based range of activity of the received signal strength from the training mode to be applied during an intruder detection mode;
comparing activity of the received signal strength in the wireless router, during the intruder detection mode, to the profile;
issuing a notification, based on the comparing during the intruder detection mode;
detecting, by the analytics module, one or more events and patterns of activity during the learn mode using the received signal strength;
detecting, by the analytics module, that the one or more events and the patterns of activity are a false alarm of an intrusion while in the learn mode or the intruder detection mode based upon the profile and received signal strength; and
updating the profile in response to the false alarm of the intrusion, wherein at least one step of the method is performed by a processor.

2. The method of claim 1 , further comprising:
monitoring, by the analytics module, received signal strength in the wireless router during the intruder detection mode; and
monitoring, by the analytics module, received signal strength in the wireless router while not in the training mode or the intruder detection mode to learn about the one or more events and the patterns of activity.

3. The method of claim 1 , wherein the profile is created by updating an initial profile that is generic to a plurality of wireless routers.

4. The method of claim 1 , further comprising:
starting the intruder detection mode in response to a request from a user; and
stopping the intruder detection mode in response to a further request from a user.

5. The method of claim 1 , wherein the learn mode includes training by a user.

6. The method of claim 1 , further comprising:
updating the profile when not in the intruder detection mode.

7. A tangible, non-transitory, computer-readable media having instructions thereupon which, when executed by a processor, cause the processor to perform a method comprising:
forming an activity profile based on a received signal strength from wireless devices as indicated by a wireless router in a training mode initiated by a user, wherein the activity profile includes at least one time-based range of activity of the received signal strength from the training mode;
monitoring the received signal strength in an intruder detection mode;
detecting a physical intruder using the received signal strength based on the activity profile and the monitoring in the intruder detection mode;
producing an alert responsive to the detecting;
detecting, by an analytics module, a false alarm of an intrusion while in the intruder detection mode based upon the activity profile and the received signal strength; and
updating the activity profile in response to an indication of the false alarm.

8. The computer-readable media of claim 7 , wherein the activity profile establishes at least one threshold for detection of human presence within a detection zone of the wireless router.

9. The computer-readable media of claim 7 , wherein:
the wireless router is configured to receive a signal transmitted from a further wireless router; and
the training mode includes training to the signal transmitted from the further wireless router as to detecting a human presence.

10. The computer-readable media of claim 7 , wherein detecting the physical intruder is based on a change in the received signal strength as indicated by the wireless router in the intruder detection mode.

11. The computer-readable media of claim 7 , wherein the method further comprises:
updating the activity profile to include patterns of activity of the received signal strength outside of the training mode and the intruder detection mode.

12. An intruder detection system, comprising:
a wireless router configured to indicate a received signal strength from wireless devices;
a memory configured to store at least one profile from the received signal strength;
an alert module configured to issue a notification responsive to being triggered; and
an analytics module configured to generate or update the at least one profile, based on the received signal strength as monitored during a learn mode initiated by the analytics module, and further configured to trigger the alert module responsive to detection of an intruder based on comparison of the at least one profile and an activity of the received signal strength during an intruder detection mode, wherein the at least one profile includes at least one time-based range of activity of the received signal strength from a training mode initiated by a user to be applied during the intruder detection mode and wherein the analytics module is further configured to detect a false alarm of an intrusion and to update the at least one profile in response to an indication of the false alarm.

13. The intruder detection system of claim 12 , wherein the alert module is further configured to couple to a server and to send the notification to the server, wherein the server is configured to perform one of: sending a text message to a mobile communication device, contacting an authority, or contacting an agency, in response to receiving the notification.

14. The intruder detection system of claim 12 , further comprising:
a timer configured to apply to timing activity of the received signal strength that exceeds a threshold for detection of human presence.

15. The intruder detection system of claim 12 , wherein the wireless router is further configured to share information regarding the detection of the intruder with a further wireless router.

16. The intruder detection system of claim 12 , wherein the wireless router further comprises at least one input configured to perform at least one of: activation of the learn mode, deactivation of the learn mode, activation of the intruder detection mode, deactivation of the intruder detection mode, or delayed activation of the intruder detection mode.

17. The intruder detection system of claim 12 , wherein the wireless router is further configured to couple to a server, wherein the notification issued by the alert module is such that a mobile communication device can, via the server, receive or check for an intruder alert per the notification from the alert module.

18. The intruder detection system of claim 12 , wherein the analytics module is further configured to modify the at least one profile responsive to at least one of: a false alarm, training, and activity of the received signal strength in a mode separate from the learn mode.
