By default, when searching the archive, the system searches for motion in all directions. It is possible to prevent searching for motion in one or several specific directions.
Click with either mouse button to designate a direction in which you do not want to perform movement search (privacy mask). The sector corresponding to the direction is then colored gray. If necessary, repeat this action for other directions. To reactivate searches for a masked (gray) direction, click it again with either mouse button.
The required directions of an object’s movement are now set.
