This action starts the export of a snapshot or a video. You must configure the conditions to start a macro beforehand (see Configuring filters for event-driven macros).

To configure, set up the following parameters:

  1. Export agent (1)—select the Server (formally the Export agent object) to which you want to export the video recording (see Configuring Export agent).

  2. Camera (2)—select a camera for export. An implicit selection of a video camera is also allowed—Camera that initiated command execution.

    Attention!

    If the start of the macro was triggered by the activation of input or output (see Configuring filters for event-driven macros) that is not connected to any camera, you need to select a specific camera here. If you select a group of cameras or a camera that triggered the command, the action will not start.

  3. Archive (3)—select an archive for export.

  4. Set the export interval (4). 

    Option

    Description

    Image export

    Exports a snapshot with the time stamp identical to the start time of action. Important! The image cannot be exported if the video camera does not have an archive

    Time schedule

    You need to select a time schedule.

    Exports images from within time schedule. Video recording interval − [Beginning of the specified time slot; the end of the specified time slot]

    During:

    You should set the export duration in HH: MM: SS. The starting point of the exported video is the command start. End point is defined on the basis of the specified duration −

    (Interval [command start; command start + duration])

    Finish after

    Select one or more events that will trigger export stop. The starting point of the exported video will be the command start, the end point − the moment of receiving any these events

  5. You can click the  button to add additional parameters:

    1. File name (5).

      Attention!

      You can use the following templates for file names and text comments:

      • %startTime% , or [START_TIME], or {startTime}: the starting time of exported interval.
      • %finishTime% , or [FINISH_TIME], or {finishTime} : the finishing time of exported interval.

        You may use the following templates for macros triggered by a text message from an event source (see Configuring filters for event-driven macros):

      • %startEvent%, or [START_EVENT], or {startEvent}: an event that triggered exporting.
      • %finishEvent% , or [FINISH_EVENT], or {finishEvent}: an event that stopped the export.

    2. Comments superimposed as captions over the exported video (6).

    3. Offset (7) is a time period used to roll back the start time of exported video. If you set this this parameter to non-zero, the time interval of the exported video will be as follows:

      [action start − (duration + offset); action start − offset].
      If exported video(s) fall into a specific slot on Time schedule, this parameter is used to define the start time for video retrieval. For example, if you set the Offset (GUI: Buffer) to 48 hours, all videos from the given Time schedule slot recorded within 48 hours before the action start will be exported.

Example: A macro command for automatically exporting video recordings of all alarm events evaluated by operators as "confirmed".
