Abstract: 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.

Abstract: In an image-recording device using a disk-type recording medium generated under the DVD+RW standard, a disk information-acquisition unit 250 acquires information about a disk 49, a disk-determination unit 260 determines that the disk 49 is a subject disk that is of a DVD+RW type and that stores video data generated by using a DVD menu and/or still-image data recorded onto the disk, an additional recording-control unit 220 controls additional recording performed for the disk 49 according to a result of the determination performed by the disk-determination unit 260, and a message display-control unit 270 makes a display unit 280 show a confirmation message used for shifting to a mode relating to the pros and cons of performing the additional recording and/or a message adapted to confirm that the DVD menu and the video data are updated, so that a mismatch which may occur between the DVD menu and/or the video data, and recorded image data is reduced.
