Security Monitor Pro: Masking an Area

Masking an Area

The Mask feature allows you to block motion detection in a particular area.  You can select an area to mask in the preview window.  This reduces the possibility of unwanted triggering of alerts.  For example, you want to monitor your garden but do not want the motion on the road outside it to be taken into account, you can mask the portion of the Preview that shows the road.

Each camera can be masked individually.  Select a camera.  Click on Tools > Mask (followed by the name of the selected camera) or the mask icon on the preview and monitoring control bar of the camera to use this feature.  A message box appears and tells you about how to select and mask an area in the preview window.  Click OK to close the message box.  The mask icon on the control bar changes to the Unmask icon.

A rectangular box with red dotted border appears in the Preview window.  Drag it to cover the part of the window you want to mask and resize it by dragging the edges of the box.  You can resize the mask rectangle or disable masking only when monitoring is turned off.  The Log shows an entry telling you that motion would not be detected in the masked area.

To unmask the selected area for an individual camera, open the Tools menu and click Unmask (followed by the name of the selected camera) or click on the unmask icon on the preview and monitoring control bar.

Mask settings persist, that is, they are saved when you switch between cameras or close the application.
