Example implementations include a method, apparatus, and computer-readable medium comprising determining, by a processor of a control panel, that a security event has happened; and capturing still images or videos by a camera in the control panel subsequent to determining that the security event has happened. In some implementations, the camera is a forward-facing camera. In some implementations, determining that the security event has happened comprises detecting a motion using the camera in the control panel. In some implementations, determining that the security event has happened comprises receiving a signal indicative of activation of a door switch of a door located next to the control panel. In some implementations, the security event is associated with one or more Bluetooth devices being in range, and determining that the security event has happened comprises using a Bluetooth radio in the control panel to detect the Bluetooth devices.

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 is indicative of a security event. In some non-limiting implementations, the control panel may be configured to detect events based on various noise detection models, such as continued noise level above a threshold, noise associated with multiple short sharp impacts (e.g., an intruder trying to kick down a door), gunshot detection, voice recognition to identify a request for assistance (e.g., a person asking for help), glass break detection, or detection of a particular standardized pattern of beeps such as the temporal-three pattern of a smoke detector going off (according to ISO 8201 and ANSI/ASA S3.41 Temporal Pattern), the temporal-four pattern of a carbon monoxide detector going off, etc.

Example implementations include a method, apparatus, and computer-readable medium comprising executing a diagnostic tool locally at a control panel; and providing, by the diagnostic tool, via a display of the control panel, information related to a signal strength of a connection between the control panel and at least one device configured to communicate with the control panel over the connection.

Example implementations include a method, apparatus, and computer-readable medium comprising first broadcasting, by at least one primary speaker of a control panel, a first sound toward a front or a side of the control panel; and second broadcasting, concurrently with the first broadcasting, by a removable back speaker that is removably attachable to a back side of the control panel, a second sound toward the back side of the control panel. In some aspects, the removable back speaker is configured as a stand for placing the control panel on a flat surface.

An audio riser active electrical supervision system includes a high-voltage audio alert system connected to a riser circuit. The high-voltage audio alert system disconnects a high-voltage analog signal from the riser circuit when the audio riser active electrical supervision system operates in a standby mode, and connects the high-voltage analog signal to the riser circuit when the audio riser active electrical supervision system operates in an active alert mode.
