In many occasions, the wall display is integrated in a large networked infrastructure, and should be able to display images coming from many different sources. These sources can be located in many different places around the world. In that case, you need these networked video wall controllers.
The concept of networked visualization is very easy to understand. Simply connect a source (a road camera, a sensor, a computer, etc.) to the suited encoder to get the video, images or data into the secure IP-based system. The standard internet infrastructure will transport this information wherever you want, all over the world. At the destination side, a decoder makes sure the information is ready for use on any display. Service nodes can be added to the network for additional video wall processor support.
Such a networked system is essential in critical decision-making environments. Here, all stakeholders (including higher management, control room operators, remote experts and field workers) need to collaborate in the most efficient way possible. This includes sharing information between the control room, the breakout-rooms and to field workers. The control room often operates as a central intelligence hub, where all information is gathered, processed and distributed.
