You can set up and use a real-time monitoring video wall in a financial network like a stock exchange; a telecom network; banks monitoring security in their ATM networks; for progress and accident monitoring systems on oil rigs…The list goes on…
When you design a video wall for a real-time monitoring application, you have to keep certain points in mind. These are performance and image quality, reliability, and user accessibility. This is important, as the video display will be running 24 x 7.
You can design the video wall depending on what type of information you want to display. For example, it could be a geographical map showing the “network traffic” of a mobile phone service provider. It could also be any third-party application, such as real-time video, live news, and so on.
Let’s talk a bit more about what to keep in mind when designing a video wall solution for a real-time monitoring application.
1) Understand what information will be presented and select the video wall processor inputs accordingly. There could be many sources and types of display connectors. These could be VGA, DVI, HDMI, or DP. You also need to keep in mind the resolution and aspect ratio of the video wall, as well as whether it includes any high-end graphic sources.
2) Suggest to clients that they standardise High-bandwidth Digital Content Protection (HDCP) content. This is content that is much more secure and more compliant with international data-security standards because transmitted data cannot be copied as it travels across connections. But this will mean that the video wall processor and display will also need to be HDCP-compliant.
3) Define the type and number of displays depending on the space parameters in the room. For instance, you need to consider the the amount of space available at the front and rear of the display. If there is no space in the rear, choose a front-access display that is easy for maintenance. You will also need to consider the number of input sources and type of content to be displayed, especially images. For example, if there are 8 inputs (VGA/HDMI/DVI) and a 3 x 3 video wall, the processor should have 8 inputs and 9 outputs.
4) Select the display dimensions or the size of the individual image windows carefully. Your choice will require taking into account the seating arrangement in the room, the viewing distances, and the viewing angle in both the horizontal and vertical panes. It is important that each person in a monitoring function has unobstructed view of the wall, and that they are able to view the data relevant to them with clarity (especially text and small details).
5) Image performance factors, such as colour uniformity, brightness uniformity, and image quality are critical. Ideally, you should go with DLP or LED-based cubes. For a real-time monitoring application the bezel width should be as minimal as possible, preferably less than 5 mm to ensure a high-quality image.
6) Have a user-friendly touch panel interface such as an IPAD or a capacitive touch panel so that you can select the inputs and outputs. This will help you control the displays quickly and without error, especially when time is of the essence.
While all of these pointers are important, physical and operational dynamics must also be considered as part of a complete AV system design. When setting up a video wall for a real-time monitoring application, you need to determine which display technology and specifications are best for a given installation.
Do keep these points in mind when designing a video wall for real-time monitoring. Here’s to a seamless video display experience!
