1. Cameras are added starting from the upper left angle and following the chain down.

2. If you don't have enough space for display, new cameras appear only after you free up space in the grid (when the user processes an alarm (see Assessing an alarm event) if the response time or the period of any camera display expires (see Alarm processing)).

3. When you remove a camera from the layout, the shift of the displayed camera chain doesn't occur. When a new camera appears, this chain is displayed in the topmost free cell.
4. When the user specifies the fixed template, the camera display countdown restarts for all alarm cameras displayed on the layout.

The principle of operation: 

• If in the options (see Alarm processing) the specified time for the camera display on the layout is lower than the operator response time to the new alarm, then you can remove the alarm camera from the layout after the camera display time expires on the alarm layout.
• During the first 10 seconds, the cell with the new alarm is highlighted by the red frame.
• If there are no free cells, new alarms are transferred to the waiting list. The time counts down after a camera gets on the layout from the waiting list.
• An alarm doesn't disappear from the layout while the alarm assessment window is opened until the timeout expires. If you switch to another camera without assessment, the processing timer restarts the countdown.
• The camera is removed from the layout:
  • when the user completes assessing all active alarms for a camera;
  • when the time limit of camera presence on the alarm layout expires regardless of the number of accumulated active alarms;
  • when the operator response time for the newest alarm expires. Active alarms that were at the moment of layout opening are also taken into account.
• You can display a camera again after its removal only if a new alarm occurs.
