Control rooms & command centres engineering notes, UAE

01Overview

Start with the decisions people need to make.

The wall gives the team a common picture. Desk displays carry the detail each operator needs. Changing a wall layout, controlling a source computer and sharing information in a call are separate functions, with separate permissions.

We define the source list, operator tasks and routine, incident and briefing layouts before selecting the display and signal system. Existing operational applications remain under their owners’ control. Cameras and video management systems come from the client’s security contractor; security camera supply and installation are outside this scope.

Reference configurations · project selection and system tests required. The quantities below describe design examples. They do not establish tested capacity, completed installations or continuous availability. These examples use one desk monitor per operator; regulated security rooms and tasks requiring multiple monitors need a revised design.

Radio, emergency telephony, process control logic and safety systems remain separate systems. An AV wall does not replace them.

CraftWall for sources, scenes and operator control.

Our CraftWall video wall software runs on a local Linux server with GPU processing. Operators use a browser to arrange source windows, save scenes and recall the view needed for routine work or an incident.

Explore CraftWall

CraftWall for sources, scenes and operator control.
Product function	How it can serve the room	Project boundary
Mixed sources	Combine video streams, NDI, web dashboards, documents and remote desktops on the wall	Confirm each source format, access method and server load
HDMI and SDI capture	Bring approved physical video feeds into the software compositor	The selected capture hardware must expose a compatible Linux V4L2 device; verify every simultaneous input
Scenes and display surfaces	Save window geometry and grid layouts; arrange LCD or LED surfaces	GPU outputs and the pixel map determine the physical display configuration
Interactive web, RDP and VNC	Use the operator's keyboard and mouse inside a permitted source window	This requires approved network sessions; it does not establish physical USB-KVM routing or exclusive control of a shared PC
Alarms and schedules	Select a scene from an agreed HTTP event or schedule; return after an alarm while respecting a manual scene choice	Configure and test the event interface; third-party connectors are separate scope
Source recovery and standby	Restore failed sources and saved state; use a second server where hot standby is specified	Standby requires a complete additional signal path and measured recovery tests; it is outside these base configurations
Local deployment and roles	Use a local installation, offline licensing and administrator, operator and viewer roles	Validate identity integration, detailed permissions and the network needs of each source

CraftWall also includes a read-only SCADA visualisation module and video analytics. Connecting process tags, configuring analysis and allocating server resources are additional project work; they are not automatically included in these reference configurations.

The software licence is per server, without licence limits on the number of displays, sources, operators or canvases. Hardware resources still limit simultaneous operation. Confirm the selected release, licence terms and server configuration during selection.

For CR-01 and CR-02, CraftWall is an alternative implementation of the wall compositor. CR-02 retains its separate AV/KVM routing and access controller. For CR-03, demonstrate the independent outgoing programme and its content restrictions before selecting the compositor; support for several display surfaces alone does not prove this meeting workflow.

Reference configurations. Example quantities require project selection, compatibility checks and system acceptance tests. Input counts describe distinct received signals. Repeating a source in several windows does not increase the number of independent sources. All three examples require a project-specific equipment and licence schedule.

Follow the signal path for your configuration.

CR-01

Workflow, boundaries and intended result

Composition

Four source PCs, two desk monitor/keyboard/mouse sets, one compositor with four simultaneous capture channels and four panel outputs, four LCD panels, one layout-control panel and one management switch. Mounts, rack distribution, cabling and a separately sized UPS system complete the example.

Layouts and operation

A routine preset shows all four sources. An incident preset enlarges the selected source while retaining agreed context. Operators work on their local applications; the authorised layout user controls wall placement.

Boundaries

Remote KVM switching, automatic alarm integration, recording and conferencing are outside this configuration. Two operator PCs need independent desktop and wall-feed outputs. Displaying a client application does not imply direct access to its underlying service or camera streams.

Intended result

Operators can read the selected information from the agreed positions, recall layouts and identify a lost source without interrupting local computer work.

Typical architecture · not a project drawing

Workflow, boundaries and intended result

Composition

Six source PCs, six source encoders, four desk receivers, two wall receivers, four desk monitor/keyboard/mouse sets with powered USB hubs, four operator access panels, one routing and access controller, one wall-layout panel, one compositor with two capture channels and four panel outputs, four LCD panels and one managed AV/control switch. Power and installation infrastructure are counted separately.

Layouts and operation

The controller grants or rejects a control request and indicates the selected source, current owner and connection status. The proposed policy allows one controlling desk per source PC; other authorised viewers may watch without USB control. The two wall receivers select two of the six computers. A routine layout shows both; an incident layout enlarges one of them.

Boundaries

The base wall receives two sources simultaneously, not six. Showing all six requires four additional wall receivers and four additional capture channels, or a separately validated alternative ingest design. KVM permissions and exclusive ownership require a validated control application; they do not follow from purchasing endpoints. The base peripheral set is keyboard and mouse. Touch, headsets, cameras, removable storage and other USB classes require separate approval and testing. The baseline has one monitor per desk and no processor or network failover.

Intended result

Each operator reaches permitted computers, sees whether control has been granted and can release it for another operator. A wall route never grants USB control to the wall.

Workflow, boundaries and intended result

Composition

Six source PCs, two desk monitor/keyboard/mouse sets, one compositor with seven simultaneous capture channels and two independently composed outputs, one LED display package, one conferencing PC with its own control monitor, one PTZ camera and SDI-to-USB capture, one HDMI-to-USB programme capture, two wired microphone zones, one echo-cancelling audio processor, one amplifier and two room loudspeakers. A control panel, management switch, conferencing service and installation/power infrastructure support the system.

Layouts and operation

The local wall can include information sources and the incoming call. A separate outgoing programme contains only sources approved for remote sharing. The call-return input is excluded from that programme. Staff preview and explicitly start or stop sharing; camera and microphone mute states remain visible.

Boundaries

The conferencing application must support a camera and an external captured content feed in the agreed workflow. Two capture devices alone do not prove this. The programme output is independently composed, not a copy of the whole wall. The base information feeds are silent; source audio, recording, additional meeting displays, remote KVM and camera tracking are separate scope. Two microphone zones and two loudspeakers are initial quantities, not a confirmed room capacity.

Intended result

Local and remote participants discuss the selected material with intelligible speech. Information on the local wall can remain private, and neither the returning call image nor its audio is sent straight back to the remote side.

Common mistakes

And how the design process prevents them.

M01
Mistake: Calling six selectable sources six simultaneous wall inputs
Prevention: Show the two-receiver limit in CR-02 and price expansion separately
M02
Mistake: Giving everyone a shared administrator login
Prevention: Separate operator, supervisor and administrator actions; test denied requests
M03
Mistake: Treating a USB connection as permission to control a source
Prevention: Validate device classes and enforce source ownership
M04
Mistake: Sharing the complete wall into a call
Prevention: Use an independent outgoing programme that excludes the call return
M05
Mistake: Describing a UPS as processor redundancy
Prevention: State the failed component, surviving path and measured recovery
M06
Mistake: Promising alarm automation from an available API alone
Prevention: Confirm both systems, versions, licences and trigger behaviour

12Inputs and FAQ

Before we begin.

What to send us, and practical answers before the project starts.

Does CR-01 let operators switch between remote computers?

No. Its operators use their own PCs and select wall layouts. CR-02 adds switched KVM access to six computers, with one selected source per operator desk.

Can CR-02 show all six computers on the wall at once?

The base design has two wall receivers and two capture channels, so it receives two selected computers at once. Six simultaneous feeds require four more receivers and four more capture channels, or another validated ingest architecture.

Can two operators control the same computer?

The proposed CR-02 policy grants control to one desk at a time. Other authorised users may view it. Ownership requests, rejection, release and supervisor transfer must be implemented and tested in the selected controller.

Will any USB device work through KVM?

The base workflow covers approved keyboards and mice. Cameras, headsets, touch devices, storage and specialist peripherals have different bandwidth, driver and security requirements. List the actual devices for compatibility testing.

What does CraftWall include in these designs?

CraftWall provides browser-based source and scene management, interactive web/RDP/VNC windows, alarm and scheduled scene changes, and source recovery. The project determines which functions are configured. Its remote-desktop control does not replace CR-02 USB-KVM routing, and CR-03 still needs a demonstrated independent outgoing programme. Hot standby requires an additional server and signal path.

What can the remote participants see and hear in CR-03?

They receive the camera and approved briefing content through the tested conferencing workflow, plus room speech. The outgoing programme excludes the call-return image and can differ from the local wall. Returning call audio is excluded from the outgoing audio mix.

What happens when equipment fails?

Each base example has a single processing path. A UPS protects agreed loads against a power interruption for its specified duration; it does not replace a failed processor or switch. Additional redundancy is designed and tested against the required failure scenarios.

Can existing security and operational systems be reused?

We assess their approved display interfaces and access rules with their owners. Cameras, VMS, process logic and safety functions remain with the responsible contractors. Regulated security rooms require a specific design; the example desk and network counts are not a compliance schedule.
