Video Walls to Capture Attention and Make an Impression

Video walls take digital signage to an entirely different level. Engagement metrics sky rocket as videos are better at capturing and retaining attention and people tend to remember more from video content than they do imagery alone.

To take things further, a video wall is much more than just a screen to play video streams or motion advertisements with voiceovers. They’re essential in larger arenas to relay information to an audience in real-time.

When you’re in a large venue such as a concert hall, the screens over and surrounding the main stage are huge, not visibly connected together yet they display the same event happening on the stage at the same time. This is a type of video wall that’s using video capture cards to capture the video first, then relay that content onto the network turning it into digital data that’s then transferred to the video monitors to relay the real-time information.

In a commercial environment such as shopping malls and cinemas, that real-time video capture and redistribution isn’t a necessary component as multiple screens can be displaying a variety of videos with the sound muted or with one soundtrack used over multiple muted video displays.

How Video Alls Work

The idea behind video walls is to create a gallery type wall with multiple screens to either play more than one video simultaneously or to straddle a video between multiple displays with what’s better described as a tile effect. A tile effect video wall display can be created by aligning more than one screen to create a larger display such as a 2×2, 3×3 or a wider 6×2 where six screens would hang together over two rows for a total of 12 screens however the biggest we can offer is an impressive 5×5. Just as a PC can be used to have multiple screens operating different programs at once or have the screens merge into one larger display, the same can be done with a video wall letting you create one large area to display videos that can be on a screen from floor to ceiling and without a projector needed to beam the content to it. It’s all done using a zero client and nothing more than the PC (and another for backup) to control the videos displayed across multiple screens.

Using Zero Clients to Create Video Walls

A zero client creates a virtual desktop interface that’s controlled by a PC enabling centrally managed content. Standard practice is to connect two PCs with a zero client to control what’s displayed on video walls with the second PC used as a fail-safe should a technical glitch occur on the main PC powering the video wall content.

The advantage to this, and something that keeps costs down is there’s no hard drive to install, no processor or any moving parts that’s liable to break are involved. All that’s used to connect a zero client is an HDMI connection to connect it to the PC then to the network using an ethernet switch. Video content can be streamed from videos stored on a PCs hard drive, flash drive or streamed directly from the cloud or from video capture cards to show real-time footage on multiple screens.

You can be creative with video walls too as they don’t need to look like screens. You can hang them creatively in groups to create an artistic video wall display with multiple screens hanging in different directions, yet displaying the video content at the right angle.

Businesses have a lot of options with video walls. The trickiest part is the video wall installation, but once it’s up and your hardware fitted with a compliant zero client, updating the media shown on video walls is easy to do. It’s the one digital signage that never fails to make an impression whether you install an artistic display or just a 2×2 video wall installation.
