Tips to consider before selecting a Video wall

High quality video walls are being deployed in variety of applications: control rooms for critical infrastructure, broadcast, security and surveillance monitoring, to name just a few. Selecting a right video wall is a complex task as it requires a lot of brain storming sessions internally. So, here are few things you need to be sure about before selecting the right video wall for your operation:

Ultra-reliable operation

Video walls in control rooms are expected to carry out ultra-reliable operations. So, make sure that the one you choose is capable of running 24x7, has high MTBF (mean time between failures), low MTTR (mean time to repair) and built-in redundancies to support mission critical application.

Display size

Before deciding on the size of the display, a lot of factors have to be considered. The user needs to analyze the size of room, application for the video wall, operator seating plan, budget for the project and front or rear access possibilities. After analysis of the above factors, the user can decide on the size of the display which is required and feasible.

Display resolution

Resolution also plays a major role in deciding on the Video wall. Video wall comes in various resolutions like XGA, SXGA+, UXGA, Full HD, WUXGA and 4K. Before deciding the resolution for your video wall, you need to consider factors like lighting inside the room, content which will be run on the video wall, font size of the content and viewing distance from control desk. These factors ensure that the display resolution caters to your need.

Display brightness

The brightness of the Video wall should not be low or dull. A minimum of 200cd/sqm is required to avoid risk of operator fatigue.

Viewing angles

Viewing angles should also be considered before finalizing the video wall. Viewing angles from Control desk to Video wall should not be narrow. The user may consider linear or curved set up to increase the viewing angles.
