# Show on Alarm Layout

Navigation: Working with Nx Witness > Events Rules > Available Actions > # Show on Alarm Layout |

Nx Witness provides the ability to dynamically create Alarm Layouts. An alarm layout opens certain cameras when a specific event occurs, with a special "Alarm" title and icon.

For instance, a rule can be configured as follows: if motion occurs on cameras 1 or 2, open cameras 2, 3, and 4 in an Alarm Layout.

Basic Parameters

Camera(s) to show on Alarm Layout. To specify:

1.Click on Select at least one camera in the desired row on the Alarm/Event Rules form (see "Events Rules"). The following form will appear:

2. Check the cameras to display, then click OK (Cancel will discard changes).

To select all cameras on a specific server, check the corresponding box. To filter search, use the Filter box. Filter criteria is the same as search criteria. It is possible to drag-and-drop the selected cameras from Resource Tree onto the a ction's advanced settings form.

Advanced Parameters

Interval of action – no more than once per certain amount of time (to reduce the amount of events), or instant.

Users to show alarm to – it is possible to show the Alarm Layout to only certain users. If several events are configured to show different cameras on alarm layout for the same user, the corresponding cameras will be added upon the Event occurrence. If several Events are configured to show different cameras on alarm layout for different users, each user will see the separate Alarm Layout.

Force Alarm Layout opening – if checked, when Event occurs Alarm Layout will show up immediately. If not, the Alarm Layout will be created, but the user will still be watching the current layout and will be able to switch to Alarm Layout.

Also show source camera – available only if Event is bound to cameras. If checked, when Event occurs Alarm Layout will contain camera that created Event. For instance, if Rule is set up to show cameras 2 and 3 and if motion occurs on Camera 1, Alarm Layout will contain Cameras 1, 2 and 3. If unchecked, it will contain only Cameras 2 and 3.

May be caused by

All events.

Why Action may work incorrectly

Alarm Layout is not showing to a certain user
