A portable camera may be activated in response to the activity of a firearm. Furthermore, an individual who discharged a firearm may be identified. Furthermore, information related to the firing of a firearm may be recorded, assessed, identified and transmitted. Furthermore, the status of an implement at a mount may be monitored. Furthermore, a charging device for delivering electrical power to components of a firearm may be used. A communications channel may be established between a firearm telematics sensor and a video camera, optionally by means of intermediary devices. A communications channel may be established between a mount (e.g., holster) telematics device and local and/or remote monitoring service components, optionally by means of intermediary devices. When the telematics sensor detects that its associated firearm has been removed from a holster, is in motion, or is being discharged, the telematics sensor may signal the video camera to initiate recording.
