Security by design

Many screens.
Zero network.

Between your sources and your walls, everything runs over HDMI and capture cards. No network cable, no stream crossing a sensitive information system. That's the guarantee of total isolation.

Built for the operations centre

The power of the collective

In an emergency operations centre (COD), several specialist desks - SDIS (CODIS), SAMU, gendarmerie (CORG), Prefecture, communications - work side by side. The room commander is the conductor: they call out a decision out loud, each operator clicks once on their workstation. Everyone sees the same thing. No one needs to master the software - each stays an expert in their own field.

🎙️

The room commander

The conductor of the crisis. They call out "switch to the Flood Crisis preset" - no technical handling in the heat of the moment, just a collective decision already prepared.

👥

The specialist desks

Each one pushes its sources with one click: the fire desk its field cameras, EMS its dispatch, the civil authority its mapping.

The shared wall

A common view, synchronised in real time. The whole room sees the same thing, at the same moment - the basis of a collective decision.

Compatible with NexSIS SYSTEL ARTEMIS
The best of both worlds: industrial rigour combined with the flexibility of the collective.

All your sources

Far more than capture cards

Cameras, drones, screens, web pages, files, remote shares, terminals… If it shows up somewhere, CollectivView puts it on the wall. All in the same tile, freely mixed.

The problem

Video walls are too complicated. Not any more.

Most solutions need a technician for every change. CollectivView is built to be used by the operator, live.

⚠ Without CollectivView

  • Heavy reconfiguration for every change of situation
  • An IT specialist needed to move a source
  • Overpriced proprietary hardware
  • Streams travelling over the network or an external cloud
  • An annual subscription that never stops

✓ With CollectivView

  • Pre-saved scenarios, recalled in one click
  • The operator drives alone, in real time, by touch
  • Standard off-the-shelf PCs + real pro capture cards
  • 100% HDMI, zero network between screens
  • Perpetual licence, paid once

Frequently asked questions

The answers, before you start

Security, hardware, integration, troubleshooting: the essentials at a glance.

Do I need an internet connection?
No. CollectivView runs 100% offline, locally on your workstation ("Local First"). No cloud, no data leaving the room, no dependency on a connection. It's a sovereignty choice, essential in the crisis room.
What hardware does it run on?
Windows 10 or 11 (64-bit), with .NET 8 and WebView2. 16 GB of RAM minimum (32 GB recommended) and a recent graphics card: capturing several PCs at once takes resources, don't undersize the machine. On the capture side, prefer real professional cards - Elgato Cam Link Pro, Blackmagic DeckLink Quad - for a stable, clean signal.
How many sources and screens can be shown?
Up to 20 tiles per workstation, across 12 source types (capture cards, web, IP streams, RDP/VNC/SSH/Telnet, QuickShare, files…), spread over several walls and mosaics. The real limit depends on your licence and hardware.
Compatible with NexSIS, SYSTEL, ARTEMIS?
Yes. CollectivView fits into the French emergency-services ecosystem: show the SYSTEL or NexSIS console via RDP, NexSIS web or ARTEMIS as a Website tile, follow NexSIS server logs via SSH.
A website shows up blank, why?
Some sites (Google, YouTube, banks…) refuse to be embedded in another application for security reasons - it is not a CollectivView fault. For YouTube, use the youtube.com/embed/ID link; for Google Maps, an "Embed a map" link. As a last resort, show the site via a capture card connected to a PC.
No image on a capture card?
Check that the card is recognised by Windows (Device Manager) and close any other capture software: most cards (Cam Link, Magewell, Avmatrix…) do not share their signal. For Blackmagic DeckLink cards, install the official Desktop Video drivers. Restart CollectivView after connecting.
Video freezes or stutters?
Often a CPU-load issue: above 80% sustained, it stutters. Reduce the number of active tiles or switch some to X1 instead of X4. For internet streams, check the bandwidth (a 4K feed needs at least 25 Mbit/s sustained). On an older PC, disabling large icons and tile background colour can lighten the display.
RDP, VNC, SSH, Telnet: what's required?
These sources require a network gateway service on your local network. Ask your administrator whether it is available - they will also provide the values to enter (address, port, credentials). You don't need to know the protocols in detail.
What is the licensing model and price?
Perpetual licence, paid once - no subscription, no annual fee. It is tied to the workstation (machine ID); in case of a major hardware change, EMD handles the transfer. The pack starts at €3,000 excl. VAT (software + 2 four-input multiviewers).
How do I get help?
By email at contact@easymultidisplay.com, on easymultidisplay.com, or via the EMD Discord community (peer support between users). Technical support in French and English.
