A motion in the area detector is a VMDA detection tool that triggers when the object (objects) makes some actions in a virtual area that is in the camera FOV.  

To configure a motion in the area detector, do the following:

  1. Go to the VMDA detection object settings panel.
  2. Click the Add area button (1).
  3. In the Video preview field (2), set the nodal points of the area one by one by clicking the left mouse button. Only one area can be added. If there is an attempt to add a second area, the first one will be deleted.

  4. Make the necessary operations with an area:

    Operation

    Result

    Left mouse click in the video surveillance window

    Area’s nodal point addition

    Hover to a nodal point and holding the left button pressed move the mouse

    Area’s nodal point shift

    Hover to a nodal point and press right mouse button

    Line deletion. If there are three nodal points the whole area will be deleted

  5. To select an object type for which the detector will trigger, click the  symbol. Available object types:

    1.  Any object. Detector triggers on any object.
    2.  A human. Detector triggers on an object which width is less than height.

    3.  A vehicle. Detector triggers on an object which width is greater than height.

      Note

      Detection of the following object types can be configured using scripts and registry keys: a human, a vehicle, noise, an object carried into the area, an object carried out of the area, other objects. See also CAM_VMDA_DETECTOR VMDA detection.

      More precise objects classification can be performed using the neural filter (see Configuring the neural filter).

  6. To select a detector type, click the  symbol. Available detector types are:

    1. Any movement in the area. Detector triggers due to any motion in the area.

    2. Entering the area. Detector triggers due to object’s entrance into the area.

    3. Exiting the area. Detector triggers due to the exit of object from the area.

    4. Appearance in the area. Detector triggers due to the object’s appearance in the area.

    5. Disappearance in the area. Detector triggers due to the object’s disappearance from the area.

    6. Stop in the area. Detector triggers due to the object’s stop in the area.

    7. Staying in the area for more than 10 sec (i.e. loitering detection). Detector triggers due to the object’s presence in the area for more than 10 sec. This period can be configured with LongInZoneTimeout registry key (see Registry keys reference guide).

    8. Abandoned object. Detector triggers due to the item abandoned in the area.

      Note

      To ensure the Abandoned object detector type to work, the Abandoned objects detection checkbox must be set in the Tracker settings (see Creating and configuring the Tracker object).

  7. To set the object color to be triggered by the detector, click the  icon. The color picker palette will open. Circle the required color range with the left mouse button.

    To reset the selected color range to the default value, right-click in the palette area.

  8. By default, the detector is triggered if the bottom edge of an object is detected in the area. In this case, the object is considered a rectangle (a rectangular frame around a real object), roughly divided into the following parts:


    You can change the part of the object that must be in the area for the detection tool to be triggered. To do this, in the Response area (4), set the required check box: left, right, top (upper), bottom (lower) part of the object or any point of the object.


  9. Set the Generate alarm on camera checkbox (4), if the camera alarm should be generated when the detector triggers.
  10. To display the tracks of objects detected by the cross line detection tool regardless of whether the corresponding setting of the Tracker object is enabled, set the Show event on screen checkbox (5).
  11. If the video in the preview window is too distorted, set the Show actual video aspect ratio checkbox (6). In this case, the video may not occupy the entire area of the preview window.
  12. To save the changes, click the Apply button (7).

Note

 To clear the preview field from a visual element (an area), click the Clear button (8).

A motion in the area detector is configured.
