Layout of control room screens and video walls

Whether we are talking about a manufacturing company’s SCADA control room or the control room for security staff in a store or a building, most control rooms are equipped with a number of monitors or flat-screen displays. 

What is often seen is that control rooms tend to grow in stages, with more screens set up as time goes by. This can result in a very messy control room and screens of various ages and quality, which can turn monitoring into a tiring job. Moreover, older screens are often not designed to stay on 24/7/365. And yet another challenge arises if there is a requirement for special solutions with several screens operated from the same keyboard and mouse, or for the option of showing several types of application and user interfaces at the same time (and on the same screen).

Inter-connected screens and video walls

Modern control rooms can be equipped with inter-connected screens or what is popularly called a “video wall” or a “display wall”. The interconnected screens are usually mounted close to each other and have a display that goes from edge to edge – i.e. the screen’s physical frame has a very small edge. If, for example, four inter-connected 55” screens are used, you get a large contiguous area of screen (2.4 x 1.3 metres), in which the picture shown can go ‘across’ the four physical units so that they function as one large screen.

Controlling the pictures shown

With inter-connected screens and video walls, the picture shown can be controlled in an effective way. The configuration software that comes with them allows you to freely design screen layouts and perspectives that can consist of several picture sources. These layouts can be saved and used later. 

For example:

Three different layouts are created:

  1. A layout for the day shift: This layout consists of pictures from four different video cameras, the access control system’s alarm user interface, and the system that registers all current meeting bookings with the company’s employees. You might add a particular website you want, either from the Internet or from the company’s intranet.
  2. A layout for the evening/night shift: This layout consists of pictures from two thermal video cameras and four video cameras in illuminated areas as well as the intrusion alarm system’s user interface. 
  3. For production process operators, there are layouts with various SCADA screen images together with a display of the system containing production specifications and current orders.
  4. Predefined layouts can also be automatically shown, for example in the event of a fire alarm, where the layout might include the video cameras that can assist in an evacuation.
