Abstract

A system for detecting a discharge of a firearm includes a detection component and an appropriation component. The detection component is configured to detect a discharge of a firearm within a building using one or more sensors communicatively coupled with a central server. The appropriation component configures one or more telephones within the building to gather and transmit audio data to the central server, in response to detecting the discharge of the firearm.

Claims

1. A computer readable storage medium comprising program code for causing one or more processors to perform a method, the method comprising:

detecting a discharge of a firearm within a building using one or more sensors communicatively coupled with a central server; and

in response to detecting the discharge of the firearm, configuring one or more telephones within the building to gather and transmit audio data to the central server.

2. The computer readable storage medium of claim 1, wherein the one or more sensors comprise a microphone.

3. The computer readable storage medium of claim 2, wherein detecting the discharge comprises detecting an acoustic signature of the discharge using the microphone.

4. The computer readable storage medium of claim 3, wherein detecting the acoustic signature of the discharge comprises detecting a high intensity sound with a fast rise time.

5. The computer readable storage medium of claim 3, wherein detecting the acoustic signature comprises detecting an acoustic signature based on a low frequency audio feed from the microphone, wherein audio in higher frequencies is filtered out of the low frequency audio feed.

6. The computer readable storage medium of claim 3, wherein detecting the acoustic signature comprises detecting an acoustic signature based on a non-vocal frequency feed from the microphone, wherein audio in vocal frequencies is filtered out of the low frequency audio feed.

7. The computer readable storage medium of claim 2, wherein the one or more sensors further comprise a digital signal processor to analyze audio data from the microphone.

8. The computer readable storage medium of claim 1, wherein the one or more sensors comprise an optical sensor.

100. A system for detecting a discharge of a firearm, the system comprising:

a detection component configured to detect a discharge of a firearm within a building using one or more sensors communicatively coupled with a central server; and

an appropriation component configured to, in response to detecting the discharge of the firearm, configure one or more telephones within the building to gather and transmit audio data to the central server.

101. The system of claim 100, wherein the one or more sensors comprise a microphone.

102. The system of claim 101, wherein the detection component detects the discharge by detecting an acoustic signature of the discharge using the microphone.

103. The system of claim 102, wherein the detection component detects the discharge by detecting a high intensity sound with a fast rise time.

104. The system of claim 102, wherein the detection component detects the discharge by detecting an acoustic signature based on a low frequency audio feed from the microphone, wherein audio in higher frequencies is filtered out of the low frequency audio feed.

105. The system of claim 102, wherein the detection component detects the discharge by detecting an acoustic signature based on a non-vocal frequency feed from the microphone, wherein audio in vocal frequencies is filtered out of the audio feed.

106. The system of claim 101, wherein the one or more sensors comprise a digital signal processor to analyze audio data from the microphone.

107. The system of claim 100, wherein the one or more sensors comprise an optical sensor.

120. The system of claim 100, wherein the one or more sensors comprise a plurality of sensors mounted in a plurality of rooms within the building.

121. The system of claim 100, wherein the detection component is further configured to receive sensor feeds from the one or more sensors, wherein the detection component detects the discharge based on the sensor feeds.

122. The system of claim 100, wherein the detection component detects the discharge based on receiving an indication from the one or more sensors that the discharge has been detected.

123. The system of claim 122, wherein the detection component is further configured to receive sensor data corresponding to the discharge, and wherein the detection component is further configured to confirm, at the central server, that the discharge occurred based on the received sensor data.

124. The system of claim 100, wherein the appropriation component configures the one or more telephones to gather audio data by configuring the telephones to gather the audio data using a corresponding microphone.

125. The system of claim 100, wherein the detection component detects the discharge using a sensor of the one or more telephones to detect the discharge.

126. The system of claim 125, wherein the appropriation component configures the one or more telephones to gather audio data by configuring at least the one or more telephones used to detect the discharge to gather the audio data.

127. The system of claim 126, wherein the one or more telephones used to detect the discharge comprise telephones located in one or more public areas of the building.

128. The system of claim 126, where the appropriation component configures the one or more telephones by configuring at least one telephone not used to detect the discharge to gather and transmit the audio data.

156. The system of claim 100, further comprising a countermeasure component configured to control lights within the building in response to the detection component detecting the discharge of the firearm.

170. The system of claim 100, wherein the one or more sensors comprise a plurality of sensors disparately located within the building.

188. The system of claim 100, wherein the appropriation component further configures the one or more telephones to transmit a time stamp.

189. The system of claim 100, wherein the appropriation component further configures the one or more telephones to transmit a location stamp.

190. The system of claim 100, wherein the appropriation component further configures the one or more telephones to transmit calibration data indicating a sensitivity of a microphone.
