Adaptive exit arm times based on real time events and historical data in a home security system

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

receiving a user input at a time (T 0 ) setting the security system into an alarm mode;

arming a first set of sensors in the security system when a first arm time after T 0 expires;

arming a second set of sensors in the security system when a second arm time after T 0 expires, the second arm time being longer than the first arm time,

where “arm time” refers to an amount of time during which a sensor will not trigger an alarm after the security system has been set into the alarm mode.

2. The method of claim 1 , wherein the first set of sensors are disposed at perimeter windows and/or entry points of the premises, and the second set of sensors are disposed at interior positions of the premises.

3. The method of claim 1 , wherein the first arm time is zero seconds.

4. The method of claim 1 , further comprising:

detecting that all users have exited the premises; and

arming the first set of sensors and the second set of sensors upon the detection, regardless of whether the first arm time or second arm time has expired.

5. The method of claim 4 , wherein the detection is based on one or more geo-fence signals from one or more user devices.

6. The method of claim 4 , wherein the detection is based on data obtained from one or more cameras installed at the premises.

7. The method of claim 1 , further comprising:

determining an amount of time ΔT that expires between T 0 and a last event detected by any sensor in the first or second set of sensors;

storing the time ΔT in a data log; and

setting the second arm time to an amount=ΔT+X T , where X T is a predetermined buffer value.

8. 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 captured data;

an interface configured to receive a user input setting the security system into an alarm mode at a time (T 0 ); and

a processor configured to arm a first set of sensors in the plurality of sensors when a first arm time after T 0 expires, and to arm a second set of sensors in the plurality of sensors when a second arm time after T 0 expires, the second arm time being longer than the first arm time,

wherein “arm time” refers to an amount of time during which a sensor will not trigger an alarm after the security system has been set into the alarm mode.

9. The security system of claim 8 , wherein the first set of sensors are disposed at perimeter windows and/or entry points of the premises, and the second set of sensors are disposed at interior positions of the premises.

10. The security system of claim 8 , wherein the first arm time is zero seconds.

11. The security system of claim 8 , wherein the processor is further configured to:

detect that all users have exited the premises based on one or more signals; and

arm the first set of sensors and the second set of sensors upon the detection, regardless of whether the first arm time or second arm time has expired.

12. The security system of claim 11 , wherein the processor detects that all users have exited the premises based on one or more geo-fence signals from one or more user devices.

13. The security system of claim 11 , wherein the processor detects that all users have exited the premises based on data signals from one or more cameras installed at the premises.

14. The security system of claim 8 , the processor is further configured to:

determine an amount of time ΔT that expires between T 0 and a last event detected by any sensor in the first or second set of sensors;

store the time ΔT in a data log in the memory; and

set the second arm time to an amount=ΔT+X T , where X T is a predetermined buffer value.
