Abstract

A method of controlling a security system of a premises includes detecting one or more exceptions when the system is set to an alarm mode, determining whether any of the one or more exceptions is a terminal exception, automatically executing an arming procedure according to the alarm mode when all of the exceptions are determined to be non-terminal exceptions, preventing execution of the arming procedure when any of the exceptions are determined to be a terminal exception, and, while in the alarm mode, preventing a sensor associated with a security exception from triggering an alarm when the security exception is fully corrected, and triggering an alarm when a condition that is causing the security exception is adjusted without resulting in full correction of the security exception.

Claims

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

detecting one or more exceptions when the system is set to an alarm mode;

determining whether any of the one or more exceptions is a terminal exception;

automatically executing an arming procedure according to the alarm mode when all of the exceptions are determined to be non-terminal exceptions;

preventing execution of the arming procedure when any of the exceptions are determined to be a terminal exception; and

while in the alarm mode;

preventing a sensor associated with a security exception from triggering an alarm when the security exception is fully corrected, and

triggering an alarm when a condition that is causing the security exception is adjusted such that the adjustment is performed without resulting in full correction of the security exception.

2. The method of claim 1, wherein an exception comprises a condition in the security system or in a second system in the premises different from the security system, where the condition causes either the security system or the second system to not perform as expected.

3. The method of claim 2, wherein the second system is selected from the group consisting of:

an HVAC system, a lighting system, a sprinkler system, and a multimedia system.

4. The method of claim 1, wherein the security exception comprises a breach condition detected by a sensor, the breach condition including a perimeter door or window that is not completely closed.

5. The method of claim 1, wherein the type of alarm mode is one of an AWAY mode and a STAY mode.

6. The method of claim 1, wherein a terminal exception is a condition that causes the system to be unable to function at a predetermined minimum capacity.

7. The method of claim 1, further comprising notifying a user when an exception is fully corrected.

8. The method of claim 1, further comprising arming a sensor associated with the exception when the exception is fully corrected.

9. 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 automatically;

receive data from devices installed in the premises when the security system is set to an alarm mode;

detect, based on the received data, one or more exceptions;

determine whether any of the one or more exceptions is a terminal exception;

automatically execute an arming procedure according to the alarm mode when all of the exceptions are determined to be non-terminal exceptions;

prevent execution of the arming procedure when any of the exceptions are determined to be a terminal exception; and

while in the alarm mode;

prevent a sensor associated with a security exception from triggering an alarm when the security exception is fully corrected, and

trigger an alarm when a condition that is causing the security exception is adjusted such that the adjustment is performed without resulting in full correction of the security exception.

10. The security system of claim 9, wherein an exception comprises a condition in the security system or in a second system in the premises different from the security system, where the condition causes either the security system or the second system to not perform as expected.

11. The security system of claim 10, wherein the second system is selected from the group consisting of:

an HVAC system, a lighting system, a sprinkler system, and a multimedia system.

12. The security system of claim 9, wherein the security exception comprises a breach condition detected by a sensor, the breach condition including a perimeter d that is not completely closed.

13. The security system of claim 9, wherein the type of alarm mode is one of an AWAY mode and a STAY mode.

14. The security system of claim 9, wherein a terminal exception is a condition that causes the security system to be unable to function at a predetermined minimum capacity.

15. The security system of claim 9, wherein the processor is further configured to notify a user when an exception is fully corrected.

16. The security system of claim 9, wherein the processor is further configured to arm a sensor associated with the exception when the exception is fully corrected.
