Patent attributes
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are described for implementing a smart firearm safety device. The safety device attaches to a firearm having a trigger and a slot for receiving a magazine. The safety device includes a locking mechanism that attaches to the trigger to preclude depressing a trigger of the firearm and a sensor that determines an orientation of the firearm or a relative motion of the firearm to indicate detected movement of the firearm. The safety device also includes a radio device that receives parameter signals from the sensor indicating movement of the firearm. The radio device communicates with a component of a property monitoring system to receive a command to engage the locking mechanism to preclude depressing the trigger of the firearm based on parameter signals indicating a particular type of detected movement of the firearm.
