Abstract

A security system includes a plurality of sensors installed at a premises to capture data from an environment in or around the premises, a memory configured to store data captured spanning at least a first period of time, and a processor configured to arm the plurality of sensors in an order determined based on a history of detected activity in the premises as indicated by the stored data.

Claims

1. A method of controlling a security system of a premises, comprising:

capturing data, over a period of time, with a plurality of network connected sensors installed in or around the premises;

storing the data in an electronic storage device; and

arming two or more sensors in the security system in an order determined based on a history of detected activity in the premises as indicated by the stored data.

2. The method of claim 1, wherein the order is determined by determining an arm time for each of the two or more sensors based on the history of detected activity, whereby each of the two or more sensors are armed after expiration of their corresponding arm time.

3. The method of claim 2, further comprising, prior to arming the two or more sensors, adjusting the arm times associated with each sensor based on recently detected activities.

4. The method of claim 1, wherein the order is determined by determining a first arm time for a first set of sensors based on the history of detected activity and a second arm time for a second set of sensors based on the history of detected activity, the second arm time being longer than the first arm time.

5. The method of claim 4, wherein the first arm time is approximately zero seconds.

6. The method of claim 5, wherein the second arm time is determined based on data in the stored data that indicates a plurality of times Δ

T, each of the plurality of times Δ

T being an amount of time that transpires between a time that a user switches a mode of the security system to an arming mode and a time of a last event detected by the security system thereafter.

7. The method of claim 5, further comprising including one or more additional sensors in the first set of sensors when it is determined, based on the stored data, that the one or more additional sensors detected less than a threshold amount of activity over a first time period.

8. The method of claim 4, wherein the first set of sensors comprises sensors disposed at non-entry doors and windows of the premises, and the second set of sensors comprises sensors disposed at entry doors.

9. The method of claim 5, further comprising, upon detecting that all users present in the premises have exited the premises prior to the expiration of the second arm time, arming the second set of sensors at a time that all users have been detected to have exited the premises.

10. The method of claim 9, wherein the user exits are detected by a geo-fence.

11. A security system comprising:

a plurality of sensors installed at a premises to capture data from an environment in or around the premises;

a memory configured to store data captured spanning at least a first period of time; and

a processor configured to arm two or more sensors in an order determined based on a history of detected activity in the premises as indicated by the stored data.

12. The system of claim 11, wherein the processor is configured to determine the order by determining an arm time for each of the two or more sensors based on the history of detected activity, whereby the system arms each of the two or more sensors after expiration of their corresponding arm times.

13. The system of claim 12, wherein the processor is further configured to, prior to arming the two or more sensors, adjust the arm times associated with each sensor based on recently detected activities.

14. The system of claim 11, wherein the processor is configured to determine the order by determining a first arm time for a first set of sensors based on the history of detected activity and to determine a second arm time for a second set of sensors based on the history of detected activity, the second arm time being longer than the first arm time.

15. The system of claim 14, wherein the first arm time is zero seconds.

16. The system of claim 15, wherein the processor is configured to determine the second arm time based on data in the stored data that indicates a plurality of times Δ

T, each of the plurality of times Δ

T being an amount of time that transpires between a time that a user switches a mode of the security system to an arming mode and a time of a last event detected by the security system thereafter.

17. The system of claim 15, wherein in the processor is configured to include one or more additional sensors in the first set of sensors when it is determined, based on the stored data, that the one or more additional sensors detected less than a threshold amount of activity over a first time period.

18. The system of claim 14, wherein the first set of sensors comprises sensors disposed at non-entry doors and windows of the premises, and the second set of sensors comprises sensors disposed at entry doors.

19. The system of claim 15, further comprising, upon detecting that all users present in the premises have exited the premises prior to the expiration of the second arm time, arming the second set of sensors at a time that all users have been detected to have exited the premises.

20. The system of claim 19, wherein the user exits are detected by a geo-fence.

21. A method of controlling a security system of a premises, comprising:

capturing data, over a period of time, with a plurality of sensors installed in or around the premises;

storing the data in an electronic storage device;

determining, for each of the plurality of sensors, a time value Δ

T that represents an amount of time that transpires between the security system being switched to an arming phase and a last detected event for the sensor;

determining, for each of the plurality of sensors, a respective arm time based on the corresponding time value Δ

T; and

arming the plurality of sensors during the arming phase in an order determined based on the arm times.

22. The method of claim 21, further comprising:

determining an exit allowance time based on the highest time value Δ

T,

wherein the exit allowance is set as a time by which all sensors are armed regardless of the arm times.

23. The method of claim 22, further comprising:

presenting a user with an option to increase the exit allowance time when an alarm is triggered based on an expiration of the exit allowance time and the user disarms the alarm within a predetermined amount of time; and

adjusting the exit allowance time based on user input received in response to the presented option.
