Abstract

A wireless router configured to detect an intruder. In one embodiment, a method may include 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 may also include 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.

Claims (53)

1. A computer-implemented method for detecting an intruder, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:

monitoring received signal strength in a wireless router from wireless devices during a training mode;

creating a profile of the received signal strength as monitored during the training mode, the profile comprising at least one time-based range of activity of the received signal strength during the training mode;

monitoring received signal strength in the wireless router from wireless devices during an intruder detection mode;

determining whether the received signal strength as monitored during the intruder detection mode deviates from the profile; and

in response to determining that the received signal strength as monitored during the intruder detection mode deviates from the profile, issuing a notification that an intruder has been detected.

2. The method of claim 1 , further comprising:

determining that the detection is a false alarm of an intrusion; and

updating the profile in response to the false alarm of the intrusion.

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 training mode in response to a request from a user; and

starting the intruder detection mode in response to a further request from a user.

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

6. The method of claim 1 , further comprising:

updating the profile when not in the intruder detection mode.

7. The method of claim 1 , wherein the issuing of the notification comprises posting the notification to a server, sending the notification in a text message to a user device, or sending the notification to an alarm monitoring agency.

8. One or more non-transitory computer-readable media comprising one or more computer-readable instructions that, when executed by one or more processors of one or more computing devices, cause the one or more computing devices to perform a method for detecting an intruder, the method comprising:

monitoring received signal strength in a wireless router from wireless devices during a training mode;

creating a profile of the received signal strength as monitored during the training mode, the profile comprising at least one time-based range of activity of the received signal strength during the training mode;

monitoring received signal strength in the wireless router from wireless devices during an intruder detection mode;

determining whether the received signal strength as monitored during the intruder detection mode deviates from the profile; and

in response to determining that the received signal strength as monitored during the intruder detection mode deviates from the profile, issuing a notification that an intruder has been detected.

9. The one or more non-transitory computer-readable media of claim 8 , wherein the method further comprises:

determining that the detection is a false alarm of an intrusion; and

updating the profile in response to the false alarm of the intrusion.

10. The one or more non-transitory computer-readable media of claim 8 , wherein the profile establishes a threshold for detection of human presence within a detection zone of the wireless router.

11. The one or more non-transitory computer-readable media of claim 8 , wherein:

the wireless router is configured to receive a wireless signal transmitted from a second wireless router; and

the profile further comprises information shared by the second wireless router over the wireless signal received from the second wireless router.

12. The one or more non-transitory computer-readable media of claim 8 , wherein the profile is created by updating an initial profile that is generic to a plurality of wireless routers.

13. The one or more non-transitory computer-readable media of claim 8 , wherein the method further comprises:

updating the profile to comprise patterns of activity of the received signal strength outside of the training mode and the intruder detection mode.

14. A wireless router comprising:

a receiver configured to receive wireless signals from wireless devices;

one or more processors;

one or more non-transitory computer-readable media comprising one or more computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform a method for detecting an intruder, the method comprising:

monitoring received signal strength of the received wireless signals during a training mode;

creating a profile of the received signal strength as monitored during the training mode, the profile comprising at least one time-based range of activity of the received signal strength during the training mode;

monitoring received signal strength of the received wireless signals during an intruder detection mode;

determining whether the received signal strength as monitored during the intruder detection mode deviates from the profile; and

in response to determining that the received signal strength as monitored during the intruder detection mode deviates from the profile, issuing a notification that an intruder has been detected.

15. The wireless router of claim 14 , wherein the issuing of the notification comprises posting the notification to a server, sending the notification in a text message to a user device, or sending the notification to an alarm monitoring agency.

16. The wireless router of claim 14 , further comprising:

a timer configured to apply timing intervals during the monitoring of the received signal strength in order to gauge time lengths and apply the time lengths to the profile.

17. The wireless router of claim 14 , further comprising:

a transmitter configured to transmit a wireless signal to a second wireless router, the wireless signal comprising information regarding the detection of the intruder to be shared with the second wireless router.

18. The wireless router of claim 17 , wherein the transmitter is further configured to wirelessly couple to a server in order to transmit the notification to the server.

19. The wireless router of claim 14 , wherein the method further comprises:

determining that the detection is a false alarm of an intrusion; and

updating the profile in response to the false alarm of the intrusion.

20. The wireless router of claim 14 , wherein the method further comprises:

modifying the profile responsive to at least one of a false alarm, training, and activity of the received signal strength in a mode separate from the training mode and the intruder detection mode.
