1. A method for documenting a firearm-discharge event, based on instructions from a holster telematics sensor device mounted to a holster and a firearm telematics sensor device attached to a firearm, the holster telematics sensor device having a first processor, a first sensor, and a first storage component and configured for detecting an unholstering event, wherein the first processor, the first sensor, and the first storage component are contained within a common housing of the holster telematics sensor device, and the firearm telematics sensor device having a second processor, a second sensor, and a second storage component and configured for detecting a firearm-discharge event, wherein the second processor, the second sensor, and the second storage component are contained within a common housing of the firearm telematics sensor device, the method comprising:

  • detecting, by the holster telematics sensor device, an unholstering event, wherein detecting the unholstering event comprises;

    generating, by the first sensor of the holster telematics sensor device, a presence measurement regarding the presence of the firearm in the holster, wherein the presence measurement is inductive coupling data or dielectric trace data;

    determining, by the first processor of the holster telematics sensor device, the holstering status of the firearm based on the presence measurement, wherein the holstering status is selected from a group consisting of holstered and unholstered, and storing the holstering status in the first storage component; and

    comparing, by the first processor of the holster telematics sensor device, the holstering status to a previous holstering status and identifying, by the first processor of the holster telematics sensor device, the unholstering event as a change in the status of the firearm from holstered to unholstered;

    responsive to detection of the unholstering event, sending, to a camera, an instruction to record video data;

    detecting, by the firearm telematics sensor device the firearm-discharge event, wherein detecting the firearm-discharge event comprises;

    generating, by the second sensor of the firearm telematics sensor device, a data series based on inertial measurements concerning translation of the firearm and storing the data series in the second storage component; and

    determining that a discharge event has occurred by identifying, by the processor of the firearm telematics sensor device, a portion of the data series based on the inertial measurements that is indicative of to a characteristic firearm-discharge-event pattern; and

    storing, by the firearm telematics sensor device, metadata regarding the discharge event for association with the video data in the second storage component, wherein the metadata comprise a time stamp for the discharge event.
