The described functionality is affected by Permissions to view video before and after inverted mask.

In exported videos, you can either hide any object by masking it, or hide the area around the selected object.

In order for the masked area to be displayed in the exported video file, select the export with recompression in the AviExport utility—see Selecting the format and recompression for the exported file. The masked area will not be displayed if the export is performed in any other way.

You can set the mask as follows:

  1. Go to the archive playback mode 

  2. Select Export → Hide exporting area in the camera function menu.

    Note

    Later, when viewing the archive, you can set or clear the Show hidden areas checkbox to hide or show the mask when playing back the archive.

    When setting up a mask, the checkbox must be set.

  3. As a result, the Hide area window opens, and an area with anchor points will be displayed in the Surveillance window. 
  4. Find a frame on which the object appears for the first time. You can search for videos using one of the methods described in Archive browsing.
  5. Set the required position and size of the mask by dragging an area with anchor points across the Surveillance window (1).

  6. Click Add in the Hide area window (2). As a result, the date and time of the beginning of the mask display is added to the table, and the position of the area is saved in the internal database.

    Note

    To delete a time interval, click Delete in the corresponding row of the table.

  7. Start archive playback. If the hidden object moved, repeat steps 4-6 to set the new mask position. The mask will smoothly move between the specified points to follow the object movement.

  8. Repeat steps 4-7 until the object disappears from the frame.

    Note

    You can set mask only in the first frame and in the last frame where the object is visible. However, the more points you set, the more precisely the mask hides the object.

    Note

    For the convenience of tracking an object, you can hide the mask using the Hide current area button (3). When the area is hidden, the Add button is disabled.

  9. If necessary, you can enter a comment in the text field in the Hide area window.

  10. If it is necessary to hide the area around the selected object in the exported file, then set the Inverted masking checkbox (4). As a result, the specified mask will be displayed on the video, and the area around it will be masked.

  11. If, when viewing a live or archive video in the Monitor, as well as during export, it is necessary to completely hide the screen before and after the selected segment with inverted masking, set the Hide screen completely before and after mask checkbox (5). If at the same time it is necessary that the screen is not hidden before and after when playing a live video, then set the WholeScreenHideMode key (see Registry keys reference guide).

    Note

    The Hide screen completely before and after mask setting works only for the Inverted masking. Example of use: in a video recording you want to show only the appearance of an object at a certain moment, the rest cannot be shown. In this case, an inverted mask is created around the object, and the screen before and after is hidden with the appropriate checkbox.


  12. By default, the area is masked with solid black color. You can change the value of the Method of hiding switch (6) so that the mask looks like a blurred or pixelated area.

    Note

    The selected method of hiding is applied in the exported file. When viewing the archive in the Video surveillance monitor, the area is masked in black.

  13. After completing the settings for masking areas, click the Save button (7).

    Note

    If you do not save the changes, then when you try to close the Hide area window, a warning will be displayed:

    A similar window will be displayed when trying to close the archive playback mode in the Video surveillance monitor if the changes to the masking areas settings were not saved.

To change the previously created masking area, select Export → Edit exporting area in the camera function menu:

As a result, an editing window will open, in which the masked area is shown in the form of a grid:

To edit a previously created area, repeat the steps 4-13.
