1. Depending on the Operator protocol configuration, current events can be displayed as cells with screenshots images or lines without schreenshots images (see see Configuring the interface of the Operator protocol). The number of horizontal cells is determined by the Operator protocol window width. However, the Operator protocol can be configured in such a way that the cell size fits the size of the free area under the event control panel. In this case only one cell is horizontal, and its height is equal to the height of the free area. To display events as lines, set the  checkbox, if this option is enabled in the settings for the Operator.
2. Depending on the Operator protocol configuration, the events are displayed in the order they are received or by the priority and importance, ascending or descending. When there is ascending sorting, the newest (of higher priority) event is in the upper left corner or on the top line, when there is descending sorting, it is in the bottom right corner or on the bottom line.
3. If one or several events are selected by the Operator, then their position in the Operator protocol window is not changed and new events continue appearing in the window. They shift in accordance with the sorting order. In this case, the Operator protocol can be configured in such a way that when a new event is received, its cell or line automatically becomes active.
4. The screenshot of the event is displayed in the cells of the events of the Camera objects as well as events of objects linked to cameras (see Connection of objects with cameras). If there are several cameras linked to the object, you can use the  buttons to browse the screenshots. The name of the corresponding camera is displayed on the frame.
   

   Info
   title Note
   Event cells can display not only video screenshots, but also images received from devices connected to the camera. For this, the Operator protocol must receive an event with the imageBase64 parameter, containing a base64-encoded image that should be displayed. Such events can be generated, for example, using a script.

   
   
5. Events can be displayed without grouping or can be grouped by object, event or region. Event can be grouped using the  drop-down list, if this option is enabled in the settings for the Operator.
