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:

storing data captured from one or more sensors over a period of time;

determining a first exception rule based on a trend identified in the data;

storing the first exception rule in a database;

detecting an exception based on the first exception rule stored in the database when the security system is set to an alarm mode;

transmitting, to a user, a notification identifying the exception; and

automatically executing an arming procedure according to the alarm mode.

2. The method of claim 1, wherein the first exception rule is determined based on data obtained from one or more sensors that are not a part of the security system.

3. The method of claim 2, wherein the one or more sensors are part of a second system selected from the group consisting of:

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

4. The method of claim 3, wherein the alarm mode is AWAY, the identified trend is a data from a light sensor indicating that a light is off, and the first exception is determining that the light is on.

5. The method of claim 1, wherein the first exception rule is based on a condition present in another system in the premises that causes the other system to not perform as expected.

6. The method of claim 1, wherein the notification is transmitted to the user via a text message to a communications device registered with the security system.

7. The method of claim 1, further comprising:

receiving a user input of a second exception rule;

storing the second exception rule in the database;

detecting a second exception based on the second exception rule when the security system is set to the alarm mode;

transmitting, to a user, a notification identifying the second exception; and

automatically executing an arming procedure according to the alarm mode.

8. A security system installed in a premises, comprising:

a plurality of sensors;

a data log that stores data received from the plurality of sensors;

an exception identifier that determines one or more exception rules based on data stored in the data log;

an exception database that stores one or more exception rules identified by the exception identifier; and

a processor that;

detects an exception based on an exception rule stored in the database when the security system is set to an alarm mode,

transmits, to a user, a notification identifying the exception, and

automatically executes an alarm arming procedure according to the alarm mode.

9. The security system of claim 8, wherein the exception identifier identifies one or more trends in the stored date and determines the one or more exception rules based on the identified trends.

10. The security system of claim 8, wherein the exception identifier identifies the one or more trends when data from a given sensor consistently indicates, over a period of time, that a certain condition exists under a particular circumstance, and wherein the exception identifier determines the exception rule based on the certain condition and the particular circumstance.

11. The security system of claim 8, wherein the one or more exception rules are determined based on data obtained from one or more sensors that are not a part of the security system.

12. The security system of claim 11, wherein the one or more sensors are part of a second system selected from the group consisting of:

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

13. The security system of claim 8, wherein the processor transmits the notification to the user via a text message to a communications device registered with the security system.
