5. The method of claim 1 , further comprising:

receiving the second alarm signal;

identifying a first security system zone where the second security sensor is located; and

ignoring the second alarm signal when the first security sensor system zone identifies the second portion of the premises.

6. The method of claim 1 , further comprising:

receiving designation information, designating a portion of the plurality of security sensors as sensors to actively monitor after the command is received; and

storing the designation in a memory;

wherein causing one or more security alerts comprises:

receiving the first alarm signal from the first security sensor;

determining, via use of the designation stored in the memory, that the first security sensor has been designated as one of the sensors to actively monitor after the command is received; and

causing one or more security alerts to occur when the first security sensor has been designated as one of the sensors to actively monitor after the command is received.

7. The method of claim 1 , wherein the third security sensor monitors a staircase for the presence of a person, and the third alarm signal is received when the third security sensor detects a person descending the staircase.

8. A central security monitoring device in communication with a plurality of security sensors distributed in a premises, forming a security system, for selectively monitoring a portion of the premises, comprising:

a sensor interface for receiving alarm signals from the plurality of security sensors

a network interface for communicating with local or remote networked devices;

a non-transitory memory for storing processor-executable instructions; and

a processor, coupled to the sensor interface, the network interface and the memory;

wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, a command to actively monitor a portion of the plurality of sensors; and

in response to receiving the command:

cause, via the network interface, one or more security alerts to occur when a first alarm signal is received from a first security sensor located in the first portion of the premises; and

ignore a second alarm signal received from a second security sensor located in a second portion of the premises.

9. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, the first alarm signal;

determine a sensor identification code from the first alarm signal; and

cause, via the network interface, one or more security alerts to occur when the security sensor identification code matches a security identification code stored in the memory identified as being located in the first portion of the premises.

10. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, the first alarm signal;

identify a first security system zone where the first security sensor is located; and

cause, via the network interface, one or more security alerts to occur when the first security sensor system zone identifies the first portion of the premises.

11. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, the second alarm signal;

determine a sensor identification code from the second alarm signal; and

ignore the second alarm signal when the security sensor identification code matches a security identification code stored in a memory identified as being located in the second portion of the premises.

12. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, the second alarm signal;

identify, a first security system zone where the second security sensor is located; and

ignore the second alarm signal when the first security sensor system zone identifies the second portion of the premises.

13. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the network interface, designation information,

designate a portion of the plurality of security sensors as sensors to actively monitor after the command is received; and

store the designation in the memory;

wherein causing one or more security alerts comprises:

receiving, via the sensor interface, the first alarm signal from the first security sensor;

determining, via use of the designation stored in the memory, that the first security sensor has been designated as one of the sensors to actively monitor after the command is received; and

causing one or more security alerts to occur when the first security sensor has been designated as one of the sensors to actively monitor after the command is received.

14. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

determine that a pre-determined time has elapsed from when the command was received; and

in response to determining that the pre-determined time has elapsed, cause the security system to enter into a mode of operation that the security system was operating in prior to receiving the command.

15. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the sensor interface, a third alarm signal from a third security sensor after receiving the command, the third security sensor comprising an interior sensor; and

upon receiving the third alarm signal cause the security system to enter into a disarmed mode of operation, wherein in the disarmed mode of operation, alarm signals from any of the plurality of security sensors are ignored.

16. The central security monitoring device of claim 15 , wherein the third security sensor monitors a staircase for the presence of a person, and the third alarm signal is received after when the third security sensor detects a person descending the staircase.

17. The central security monitoring device of claim 8 , wherein the processor-executable instructions, when executed by the processor, cause the central security monitoring device to:

receive, via the network interface, a custom time period from a user of the security system, the custom time period defining a time period that the security system actively monitors at least one security sensor after receipt of the command;

store the custom time period in the memory; and

determine an elapsed time from when the command was received;

determine that the elapsed time equals or exceeds the custom time period stored in the memory; and

cause the security system to enter into a mode of operation that the security system was operating in prior to receiving the command.
