Abstract: A recording device may record information continuously. Particular events which occur during recording may be of interest for review (e.g. audit, inspection). Events may be audited to ensure that the data gathered is not tampered with or corrupted and to provably establish an evidence chain of custody. Metadata may mark recorded data of an event, in whole or in part, for later review. Metadata may be identified as an audit tag which may identify particular occurrences during an event. An audit tag may be urgent or non-urgent. Notice of an urgent audit tag may be sent to a server prior to sending the recorded data associated with the audit tag. Recorded data may be cryptographically signed to protect the recorded data from tampering.

Abstract: Computer-implemented methods and systems for processing recorded data for storage is provided. An auditable device, such as a digital video camera, stores a set of recorded data. The auditable device also stores auditable event entries that represent auditable events detected by the auditable device. One type of auditable event is the receipt of information from a computer-aided dispatch (CAD) system that indicates an event. The auditable device marks at least one subset of the set of recorded data based on the auditable event entries, and uploads the marked at least one subset of the set of recorded data to an evidence management system.

Abstract: In some embodiments, auditable devices such as auditable cameras are provided. The auditable devices maintain audit trail data that is digitally signed and stored on the devices until it can be uploaded to an evidence management system. When intermittent data connections to the evidence management system are available, an auditable device may transmit records of urgent events to the evidence management system. The transmission of urgent events via ad-hoc data connections and the digital signing of audit trail data help overcome technical obstacles in establishing provably reliable data collection while minimizing power consumption by the auditable device.

Abstract: Systems involving distributed control functions are described herein. Each member or device within the system has responsibility for controlling part of the system's behavior, and includes logic to determine what action, if any, will follow as a response to determining information or receiving information from other members or devices within the system. A change of status of one member of a system may provide a basis for action by another member of the system. Status may be the result of sensing a condition of the environment, sensing the condition of a component, receiving the output of a conventional sensor, and/or sensing the condition of a link between components. In some embodiments, action taken by a member of the system may include collecting data during law enforcement activities.
