Abstract
Example implementations include a method, apparatus, and computer-readable medium comprising monitoring, by a control panel, an ambient noise via one or more microphones in the control panel. The implementations further include determining, by the control panel, whether the ambient noise includes an acoustic signature associated with a security event. In some implementations, the security event may comprise a glass break event. In some implementations, the acoustic signature may comprise a first sound followed by subsequent sounds. The first sound may comprise a thump sound, and the subsequent sounds may comprise crashing sounds.
Claims9
A method comprising:
- monitoring, by a control panel, an ambient noise via one or more microphones in the control panel;
- detecting, by the control panel, a glass break event in response to determining that the ambient noise includes an acoustic signature associated with the glass break event, comprising:
- detecting a first sound by the one or more microphones while the control panel is operating in a low-power sleep mode;
- waking up from the low-power sleep mode in response to determining that the first sound has a first frequency associated with an object impacting glass;
- and
- detecting, by the one or more microphones, one or more subsequent sounds having a second frequency associated with glass breaking into multiple pieces or glass falling onto a surface;
- and
- at least one of initiating an alarm or sending a notification by the control panel in response to detecting the glass break event.
An apparatus comprising:
- a memory;
- and
- a processor communicatively coupled with the memory and configured to:
- monitor, by a control panel, an ambient noise via one or more microphones in the control panel;
- detect, by the control panel, a glass break event in response to determining that the ambient noise includes an acoustic signature associated with the glass break event, comprising:
- detect a first sound by the one or more microphones while the control panel is operating in a low-power sleep mode;
- wake up from the low-power sleep mode in response to determining that the first sound has a first frequency associated with an object impacting glass;
- and
- detect, by the one or more microphones, one or more subsequent sounds having a second frequency associated with glass breaking into multiple pieces or glass falling onto a surface;
- and
- at least one of initiate an alarm or send a notification by the control panel in response to detecting the glass break event.
A non-transitory computer-readable medium storing instructions executable by a processor that, when executed, cause to the processor to:
- monitor, by a control panel, an ambient noise via one or more microphones in the control panel;
- detect, by the control panel, a glass break event in response to determining that the ambient noise includes an acoustic signature associated with the glass break event comprising;
- detect a first sound by the one or more microphones while the control panel is operating in a low-power sleep mode;
- wake up from the low-power sleep mode in response to determining that the first sound has a first frequency associated with an object impacting glass;
- and
- detect, by the one or more microphones, one or more subsequent sounds having a second frequency associated with glass breaking into multiple pieces or glass falling onto a surface;
- and
- at least one of initiate an alarm or send a notification by the control panel in response to detecting the glass break event.
