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.
