Command-and-control video wall solutions are as demanding as the information displayed on the end product is critical. Make sure you’re not missing important elements when selling and installing these solutions. Read on to learn about key factors that will help you greatly increase your success with command-and-control projects.
- Distance and viewing angles—Make sure the video walls used in command-and-control implementations use displays that have a high enough resolution to be readable at whatever distance people are stationed and clearly viewable at all angles from within the room. Consider an example where an important decision needs to be made based on a photo of a license plate. A poor video wall might make it difficult or impossible to distinguish between an “8” and an “E.”
- Brightness and colors—The brightness of all displays within the wall should be calibrated to the same level. It’s also critical to calibrate colors. When evaluating video footage, distinguishing the difference between an orange hat and a red one can be crucial. Avoid shortcuts like systems that are “precalibrated at the factory.” Instead calibrate within the environment the wall will be used, and not while being staged at your office. Finally, the light elements within the displays deteriorate over time and will need recalibration. This can become a great value-added service to offer your customers.
- Downtime—Due to the critical nature of command-and-control video walls, downtime isn’t an option. Make sure to offer support programs that ensure there’s not a gap in service by having the customer purchase extra displays, keeping extra units in inventory or working with Ingram Micro to ensure replacement units can be sent immediately if needed.
- Projectors carry unique challenges—Except in a few cases, LCDs are preferred over using projectors. Using multiple projectors requires edge blending to bring all the sources together into what appears as a single wall, which can be cumbersome and requires a special skill set. Projectors also require regular lamp and dust maintenance that LCDs don’t.
- Anti-image retention technology—Video walls in command-and-control centers are often active 24/7, which can cause an LCD to “stick” a pixel on or off when displaying static data (e.g., column headers or the colon between the hours and minutes of a clock). This can affect a wall’s overall viewability. With anti-image retention technology, the displays shift the content by an imperceptible amount at regular intervals.
- Consider the source—The closer the display is to the server delivering the data, the better the results. If your customer’s command-and-control room is on one floor and the server is on another, ensure their networking is reliable enough to transfer data to the wall.
Keep these elements in mind during your next command-and-control project, and you’re sure to roll out a better solution and have a happier customer.
