1. A body-worn camera system operable in at least a pre-event recording mode and an event recording mode, the system comprising:

  • a portable body configured to be carried on a body of a person, wherein the person is a law enforcement officer at a location of an event;

    a computer processor included in the portable body;

    a video camera configured to be worn on the person at the location of the event and configured to capture video of the event;

    a battery included in the portable body configured to be carried on the body of the person, and the battery configured to supply electricity to at least the computer processor and the video camera;

    a first user-operated control comprising a recording button, wherein the recording button is communicatively coupled to the video camera and configured to be actuated at the location of the event by the person;

    a second user-operated control comprising a power on-off button, wherein the power on-off button is included on the portable body configured to be carried on the person, and the power on-off button is configured to cause the battery to supply electricity to at least the video camera;

    a communication circuitry included in the portable body configured to transmit the video; and

    a memory comprising a pre-event circular buffer for storing the video corresponding to pre-event recording video while in pre-event recording mode and a portion of the memory for storing the video corresponding to event recording video while in event recording mode, wherein the pre-event circular buffer starts to be overwritten with new video from the video camera once the pre-event circular buffer is full, the memory further storing computer-executable instructions that, when executed by the computer processor, cause the computer processor to;

    if the body-worn camera system is in the pre-event recording mode;

    (A) in response to detecting actuation of the first user-operated control;

    (i) discontinue pre-event recording mode;

    (ii) save the video corresponding to the pre-event recording video stored in the pre-event circular buffer before it is overwritten; and

    (iii) begin storing the video corresponding to the event recording video in the portion of the memory; and

    (B) in response to detecting operation of the second user-operated control;

    (i) discontinue pre-event recording mode; and

    (ii) cause the battery to stop supplying electricity by powering down the body-worn camera system;

    if the body-worn camera system is in the event recording mode;

    (A) in response to detecting a holding actuation of the first user-operated control;

    (i) discontinue event recording mode; and

    (ii) begin pre-event recording mode; and

    (B) in response to detecting a non-holding actuation of the first user-operated control;

    (i) store a mark, at a point in time of occurrence of the non-holding actuation in the video, associated with the event recording video, wherein the mark in the video enables advancing playback of the video to each of a plurality of marked points in the video; and

    if the body-worn camera system is not in the event recording mode;

    (A) in response to detecting operation of the second user-operated control;

    (i) cause the battery to stop supplying electricity by powering down the body-worn camera system; and

    (B) in response to detecting actuation of the first user-operated control;

    (i) begin event recording mode.
