Sound sensors 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, a time associated with the output generated by the sound sensor;
determining, by the controller of the security system, that the time associated with the output fails to match a historical log of times associated with outputs generated by the sound sensor; and
generating, by the controller of the security system, a security event in response to the time associated with the output failing to match the historical log.
2. The method of claim 1 , further comprising sending a command to a camera to capture a video data.
3. The method of claim 1 , further comprising determining a database lacks an entry for the time associated with the output generated by the sound sensor.
4. The method of claim 1 , further comprising receiving a video data from a video camera.
5. The method of claim 1 , further comprising sending a message that notifies of the security event.
6. The method of claim 1 , further comprising instructing a video camera to align to the output generated by the sound sensor.
7. The method of claim 1 , further comprising aligning a video camera according to the output generated by the sound sensor.
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 associated with a controller of a security system;
determining a time associated with the output generated by the sound sensor;
determining that the time associated with the output fails to match a historical log of times associated with outputs generated by the sound sensor; and
generating a security event in response to the time failing to match the historical log.
9. The system of claim 8 , wherein the operations further comprise sending a command to a camera to capture a video data.
10. The system of claim 8 , wherein the operations further comprise determining a database lacks an entry for the time associated with the output generated by the sound sensor.
11. The system of claim 8 , wherein the operations further comprise receiving a video data from a video camera.
12. The system of claim 8 , wherein the operations further comprise sending a message that notifies of the security event.
13. The system of claim 8 , wherein the operations further comprise instructing a video camera to align to the output generated by the sound sensor.
14. The system of claim 8 , wherein the operations further comprise aligning a video camera according to the output generated by the sound sensor.
15. A non-transitory memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
receiving a vector direction generated by a sound sensor associated with a controller of a security system;
determining a time associated with the vector direction generated by the sound sensor;
determining that the vector direction and the time fail to match a historical log of outputs generated by the sound sensor; and
generating a security event in response to the vector direction and the time failing to match the historical log.
16. The non-transitory memory device of claim 15 , wherein the operations further comprise sending a command to a camera to capture a video data.
17. The non-transitory memory device of claim 15 , wherein the operations further comprise determining a database lacks an entry for at least one of the vector direction and the time.
18. The non-transitory memory device of claim 15 , wherein the operations further comprise receiving a video data from a video camera.
19. The non-transitory memory device of claim 15 , wherein the operations further comprise sending a message that notifies of the security event.
20. The non-transitory memory device of claim 15 , wherein the operations further comprise instructing a video camera to align to the vector direction.
