Userful’s Command & Control Module is an advanced video wall and content management system. Users can access and manage their content completely independently of the Userful Control Center with the correct permissions and setup.
In Userful Control Center, click New Source . From the drop-down menu select Command and Control and give it a name
Select an existing source to play permanently in the background, or select a black or white background image
Click OK to complete the process
Drag-and-drop your Video Wall or Zone to the Command & Control source, ensure the zone is running, and click Apply.
Unlike other sources, Command & Control is not managed from the Userful Control Center or with Interactive Viewer. From UCC, C&C looks exactly like the image above - a running zone assigned to a source. There are no virtual displays unlike Picture-in-Picture or Multi-Window.
Each instance of Command & Control created in UCC has its own Sources and operates independently of any others.
To access Command & Control, click the button on the left side of the Userful Control Center. This will open Command & Control in a new browser tab.
You will be presented with a fresh Command & Control interface.
The top bar contains a few functions:
From left to right, these are:
Saved Layouts list (see Layouts, below)
System switcher - View C&Cs of other systems on the LAN, if available
Launch Camera - Launches USB or RTSP camera attached to the system, if available
Source Names - Turns on source name overlays if Always Show Name is not checked
Live Updates - Controls live video streaming of the background sources. As this is bandwidth intensive, it is on by default if accessing C&C directly over your local network, but off by default if accessing the system via Userful Manager
Enter/Exit Full Screen - Full-screens your browser for more screen real estate
Help - Launches support resources
Local Users - Lists active users in C&C via local login
This setup is entirely different from the Userful Control Center, and designed to be intuitive. There are a number of functions immediately available, but we should create some Sources first.
Click the Sources button in the bottom left corner. You can create any type of Direct or Interactive source in the same way that they are created in UCC.
You will recognize most fields when you go to create Sources, but there are a few new ones as well.
You will notice that Interactive sources all have Scaling Options that allow you to set width and height resolutions. This tells the source what resolution it has to work with - for example, a Web Browser session given the shown resolution would then start in a window with 1280x720 resolution. This can be set to any resolution necessary, on a video wall 1920x1080 is the most common.
Scaling also gives you the ability to create sources that have non-standard aspect ratios. A resolution of 1920x2160 will create a Web Browser source perfect for a Twitter feed, for example.
The second difference you will find in C&C Sources is a check box for
Enabling this will allow the session to continue running if the source window itself is minimized. The session will not remain active if the source is closed. This allows you to have multiple active sessions running without needing to keep all of them open at once, and preserves user sessions at the cost of increased system resources, similar to the Persistent Running Session functionality in UCC.
Click to edit a Source, or to delete it.
Once you have created a few sources, click them to "launch" them to the bottom bar.
You can either single-click to launch, or click-and-drag Sources on to the canvas.
Double-clicking on a Source will cause it to expand to fill all the bezels it is currently touching.
Dragging a Source to cover multiple or all bezels and then double-clicking it will cause it to fill multiple displays or the entire wall.
You can also resize Sources with the mouse by clicking-and-dragging the edges or corners.
You can disable or enable Live Updates by clicking Live Updates at the top
You can also enable or disable name overlays for each Source
Each Source has a set of sizing controls. From left to right, these are:
Source Name - The name given to the Source during setup
Volume Control - Mute/Unmute and Volume control
Minimize - Minimize the window to the bottom bar. The session continues running if Persistent Session is checked
Expand - Source fills the displays of all the bezels it is touching. This is identical to the double-click function
Maximize - Source fills the entire canvas
Stop - Stops and closes the Source
Each Source also has its own action menu.
Hide - Minimize to task bar. Session continues running if Persistent Session is checked
Deactivate - Stops and closes the Source, ending the session
Viewer - Interactive sources only. Opens Interactive Viewer
Rename - Rename the Source
Always Show Name - Always shows the Source name as an Overlay for that particular Source, irrespective of how Source Names is set.
As you may have noticed, managing Sources in Command & Control is a lot like managing applications in a desktop OS. Take some time to familiarize yourself with creating and manipulating Sources before moving on.
Layouts allow you to save different configurations of Sources and recall them with a single click. Before creating Layouts, there are a few best practices to follow.
Have all of your Sources created ahead of time.
To save on system resources, do not use Persistent Sessions unless necessary
For the fastest Layout switches, have all of your sources open and running, and have the Layout switch simply move existing sources from background to foreground - this will create near-instantaneous Layout switches.
For Layout switches that deal with a large number of Sources, it is better to conserve resources by minimizing or closing Sources whenever possible.
Create all your Sources, then move them into the first arrangement.
Click Saved Layouts in the top-left corner of the screen, Click Save as new layout, give it a name, and click OK.
Re-arrange Sources as required and repeat the process, keeping in mind the best practices above.
To update an existing Layout, create the arrangement and click the icon. To delete a Layout, click . The pulsing green icon represents the Layout that is currently playing.
Once your Layouts are saved, they can be switched by simply clicking each one.

The access permissions for a Command and Control module are listed below. Remember that in order for a user to be able to access Command & Control, they must also be granted access to that source’s Resource Group.
Manage Source audio settings
Create, update and delete layouts
Switch between existing layouts
Open and close Sources from the list
Source interactive viewer
Use Interactive Viewer
Create, update and delete Sources
Minimize, maximize, and move Sources around the canvas
Though not fully production, by popular request Userful provides a tool to view one or more C&C dashboards from a single pane of glass - another Userful display, your own laptop or desktop, a tablet, etc.
This involves a Web browser (or Web Browser source) configured with a URL that points to the Userful server, with the addition of /dash at the end.
For example, if your Userful server is on your corporate network with an IP of 192.168.1.110, then the URL to access the Supervisor Dashboard would be http://192.168.1.110/dash.
This feature is only accessible over the LAN and not through Userful Manager due to potential for very high bandwidth usage.
This example system has 3 servers: Server_1, Server_2 and Server_3.
In order to create a dashboard accessible at
[Server_1_address:port/dash], administrators need to configure the "Peer List" within the "General" section of the Userful Control Center settings:
1. Navigate to the Peer List of Server_1 and add Server_2 and Server_3 by filling out all required fields.
2. Navigate to the Peer List of Server_2 and add Server_1 by filling out all required fields.
3. Navigate to the Peer List of Server_3 and add Server_1 by filling out all required fields
In this case,
[Server_1_address:port/dash] will show the control rooms of all three systems.
[Server_2_address:port/dash] will only show control rooms from Server_1 and Server_2.
[Server_3_address:port/dash] will only show control rooms from Server_1 and Server_3.
Administrators can control access to the Supervisor Dashboard through Role-based Access Control (RBAC) found in the Users screen of the Userful Control Center. When creating a new group, the Control Room Supervisor Dashboard flag in the Other Applications tab can be selected to enable dashboard access for all members of that group.
This view has a few options
FPS - Control the refresh rate of the wall, at the expense of additional bandwidth used
Refresh - Reload the view
Launch - Launch the full C&C interface in a new tab, if RBAC privileges allow
Hide/Show - disable or enable the feed
If the server is running more than one instance of C&C, or more than one Userful system is running a C&C session and is added in the Peer List, those C&C instances will also appear here.
