The cameras list displays the available video cameras. You can search for a camera by name or ID using the Camera field. The cameras can be added to the layout only once. The cameras which are already added to the layout are highlighted in gray. You can drag the cameras from this list onto the layout using the left mouse button. When dragging the camera, the frame displayed on the camera at the moment when it was added to the layout will be displayed on the layout.
Below the cameras list, the camera preview is displayed.

The buttons for managing the layouts:
- Apply—save changes in the layout.
- Cancel—cancel changes and go to the last saved layout.

The layout creation panel allows you to get a visual idea of how the layout will look on the Video surveillance monitor. On this panel, you can drag the Surveillance windows, add new rows and columns, and resize the Surveillance windows using the>, <, ∨, ∧ buttons. If the layout was created using the Display manager, then the frames displayed on the camera at the moment when it was added to the layout will be displayed in the Surveillance windows. If the layout was created using the Video surveillance monitor, then in order to display these frames in the Surveillance windows, it is necessary to click on the Refresh button.
