Sound signatures in security systems
Directional sound location is used to determine security events of a security system. A sound sensor reports a vector direction to a sound source of an acoustic signal. If the vector direction is historically observed at similar times, then perhaps the sound source is not considered a security event. However, if the vector direction is unknown or unfamiliar, the security system may infer the security event and notify emergency services.
1. A method, comprising:
receiving, by a controller of a security system, an output generated by a sound sensor;
determining, by the controller of the security system, that a direction based on the output generated by the sound sensor is unknown; and
generating, by the controller of the security system, a security event in response to the direction being unknown.
2. The method of claim 1 , further comprising determining the direction to a sound source that stimulates the sound sensor to generate the output.
3. The method of claim 2 , further comprising sending a command to a camera, the command instructing the camera to align to the direction to the sound source.
4. The method of claim 1 , further comprising determining a database lacks an entry for the direction based on the output generated by the sound sensor.
5. The method of claim 1 , further comprising receiving video data from a video camera.
6. The method of claim 1 , further comprising determining a time associated with the output generated by the sound sensor.
7. The method of claim 1 , further comprising sending a message that notifies of the security event.
8. A system, comprising:
a hardware processor; and
a memory device, the memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations comprising:
receiving an output generated by a sound sensor of a security system;
determining that a direction based on the output generated by the sound sensor is unknown; and
generating a security event in response to the direction based on the output generated by the sound sensor being unknown.
9. The system of claim 8 , wherein the operations further comprise determining the direction to a sound source that stimulates the sound sensor to generate the output.
10. The system of claim 9 , wherein the operations further comprise sending a command to a camera, the command instructing the camera to align to the direction to the sound source.
11. The system of claim 8 , wherein the operations further comprise determining a database lacks an entry for the direction based on the output generated by the sound sensor.
12. The system of claim 8 , wherein the operations further comprise receiving video data from a video camera.
13. The system of claim 8 , wherein the operations further comprise determining a time associated with the output generated by the sound sensor.
14. The system of claim 8 , wherein the operations further comprise sending a message that notifies of the security event.
15. A memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
receiving an output generated by a sound sensor of a security system;
determining that a direction based on the output generated by the sound sensor is unknown; and
generating a security event in response to the direction based on the output generated by the sound sensor being unknown.
16. The memory device of claim 15 , wherein the operations further comprise determining the direction to a sound source that stimulates the sound sensor to generate the output.
17. The memory device of claim 16 , wherein the operations further comprise sending a command to a camera, the command instructing the camera to align to the direction to the sound source.
18. The memory device of claim 15 , wherein the operations further comprise determining a database lacks an entry for the direction based on the output generated by the sound sensor.
19. The memory device of claim 15 , wherein the operations further comprise receiving video data from a video camera.
20. The memory device of claim 15 , wherein the operations further comprise determining a time associated with the output generated by the sound sensor.
