Abstract
The present invention involves a system and method for detecting a firearm shot. The system includes one or more sensors adapted to sense the firearm shot and transmit a signal representative of the firearm shot, and a base unit including electronics adapted to process the signal and determined whether the signal represents a firearm shot, and a communication device coupled to the electronics and adapted to communicate to one or more entities that a firearm shot has been detected. The method includes sonically detecting the firearm shot, and initiating an alarm indicating that the firearm shot took place.
Claims42
A method of detecting a firearm shot, comprising:
- providing a firearm shot detection system to detect a firearm shot, the firearm shot detection system including one or more sonic sensors to directly pick up sound having a characteristic frequency or frequencies representative of a firearm shot and transmit a signal or signals in response to the sound of the firearm shot;
- and a base unit including electronics to process the signal or signals, at least one of the one or more sonic sensors and the electronics adapted to determine if the sound is a firearm shot of multiple different predetermined firearm shots;
- and an alarm to indicate that a firearm shot of multiple different predetermined firearm shots has been detected;
- sonically sensing with said one or more sonic sensors sound having a characteristic frequency or frequencies representative of a firearm shot and transmitting a signal or signals in response to the sound of the firearm shot to the electronics;
- processing the signal or signals in response to the sound of the firearm shot with the electronics, the processing including amplifying a signal or signals from said at least one sonic sensor to a distinguishable level, combining the signal or signals with a predetermined signature signal, reducing signal noise, and determining whether the resulting signal or signals represent one or more predetermined types of firearm shots for a predetermined period of time;
- determining at at least one of the one or more sonic sensors and the electronics if the sound is a firearm shot of multiple different predetermined firearm shots;
- confirming that a fireman shot took place with at least one of a motion sensor and a heat sensor;
- initiating an alarm indicating that the firearm shot took place if the signal or signals represent a sound of a firearm shot of multiple different predetermined firearm shots and the firearm shot is confirmed.
A firearm shot detection system for detecting a firearm shot, comprising:
- one or more sonic sensors adapted to sonically sense the firearm shot and transmit a signal or signals in response to the firearm shot;
- at least one of a motion detecting sensor and a heat detecting sensor to confirm that a firearm shot took place;
- and
- a base unit including
- electronics adapted to receive the signal or signals and process the signal or signals, said electronics including a pre-amplifier adapted to amplify the signal or signals from said one or more sensors to a distinguishable level, a mixer adapted to combine the signal or signals with a predetermined signature signal, a low-pass filter and a precision rectifier adapted to reduce signal noise, and a time domain characterization mechanism adapted to determine whether the resulting signal or signals represent one or more different types of firearm shots for a predetermined period of time;
- and
- a communication device coupled to the electronics to communicate to one or more entities that a firearm shot has been detected,
- wherein at least one of the one or more sonic sensors and the electronics adapted to determine if the sound is a firearm shot of multiple different predetermined firearm shots.
