A gunshot detection system detects shooting events within a premises and interacts with building management systems installed within the same premises to guide occupants to safety and/or obstruct or trap an active shooter. Gunshot sensor units detect the gunshots and generate event information based on the detected gunshots. A shooting event response module generates and sends building management instructions to the building management systems. In response, distributed devices of the building management systems perform effect changes within the premises according to the functionality of the distributed devices (e.g. locking/unlocking doors, turning off lights, flashing strobe lights). A control panel of the gunshot detection system presents a graphical user interface for presenting response options and receiving selections of response actions to be performed by the building management systems. The shooting even response module also receives gunshot and building management event data and generates recommendation information based on the event data.

A gunshot detection system takes advantage of existing fire alarm system infrastructure by tapping a fire alarm communication network for a fire alarm system. Gunshot sensor units and/or a gunshot detection control panel receive power from the fire alarm communication network via tap units and/or tap wires, which provide electrical connectivity between the fire alarm communication network and the devices of the gunshot detection system. At the same time, the gunshot detection devices communicate via wireless links to an ancillary high-speed network. The gunshot sensor units can communicate with the fire alarm control panel via the fire alarm communication network. Even more comprehensive integration with the fire alarm system involves a hybrid gunshot detection and fire alarm control panel for controlling devices of both the gunshot detection system and the fire alarm system. Hybrid gunshot sensor units include fire detection elements such as smoke sensors and/or fire notification elements.

Earthquake detector is a solid-state device that detects the motion of a building or structure and initiates an alarm when the motion of a building or structure rises above a certain base level or threshold level of motion that is automatically calibrated or manually entered for the specific building or structure and the specific location of the building or structure. Earthquake detector measures the amplitude of movement and the magnitude of acceleration of the actual building or structure caused by a seismic event, earthquake, or other external force because this is the primary cause of damage to the building or structure and the associated potential for collapse of the building or structure. Earthquake detector has a circuit board; a microprocessor, integrated circuit, or chip; an accelerometer integrated circuit or chip; an alarm module; a connection to a power source; and a calibration control.

A gunshot detection system provides anti-tampering protection for gunshot sensor units and a control panel. The control panel monitors for tampering events, including monitoring for changes to configuration settings. When the settings are changed, even by an authorized user, the control panel generates a tampering alert and sends the alert to an operator of the control panel and/or administrators for the gunshot detection system. A similar notification might also occur when a sensor is taken offline or when an anti-tamper sensor on a housing of the gunshot sensor unit detects manipulation or opening of the housing. The control panel also monitors for tampering using machine certificates associated with the gunshot sensor units. In one example, the gunshot sensor units sign event data using the machine certificates and an arbitrary reference number known to the control panel. The control panel then verifies the signed event data to detect tampering events.

A gunshot detection system continually monitors ambient noise throughout a building, learns the building's auditory patterns, and alerts users when sounds are found to be unusual or generally indicative of a dangerous situation. For example, gunshot sensor units positioned throughout the building include microphones. During a learning period (e.g. during normal conditions), these microphones capture ambient noise. The gunshot detection system generates ambient noise models representing the ambient noise during the normal conditions. The gunshot detection system then continually processes currently captured audio data depicting ambient noise (and potential acoustic anomalies) against the ambient noise models to detect and/or identify the acoustic anomalies and to determine whether to generate an alert.
