Key Things to Consider for a Successful Video Wall Deployment
Deploying a video wall involves a lot of planning. As with any new project, some ground work has to carried out and some key considerations have to be taken into account. “There are many variables that can make or break your video wall deployment, and being prepared is the best way to achieve a successful deployment that will both impress your audience without breaking the bank”, explains Tim Griffin, CTO of Userful Corporation, a leading software appliance company that provides a simple and affordable solution for AV & IT professionals to easily control large numbers of displays and interactive content sources from any browser.
What you need to consider:
1. Layout & Sizing
Determine your audience and the type of message(s) you want to send via your video wall and how often these messages will change. Is your goal clear communication of specific written messages (grid layout) or is to make an impact with a unique design (artistic layout)?
2. Location and placement
Obviously you want to choose a prominent location but be aware that sun or bright lights can darken the display and create glare. Consider your surroundings and lighting conditions to ensure visibility and legibility at various times of day.
3. Wiring & Connectivity
Your host PC can be either at the video wall location or in the server room. If it is at the video wall location you can use a wireless network connection (for content access) if it is in the server room you will need to have at least one Cat5e (or Cat6) Ethernet cable going to a gigabit switch at the video wall location. Alternatively you can have one cable per screen and have your switch in the server room as well.
There are a wide range of video wall mounts. you need to ensure your wall and mounting system can handle the weight and size of the displays. Zero client devices can be mounted to the back of your displays using double-sided adhesive foam tape or vesa mounts. The power for the zero client device can be provided either from a power adaptor or a USB port on the display. The zero client devices can be set to always power on automatically (via either a dip switch or rocker switch). If you are mounting directly on the wall and you have more than a few rows of displays ensure there is sufficient space for the heated air from the displays to rise. If you are recessing the displays to be plush with the surface of the wall ensure there is vending or active cooling to ensure that displays don’t overheat. Be sure to know you have enough space behind the display for cooling fan systems and the recessed cavity is built with sufficient either passive or active venting in mind.
In addition, you’ll want to make sure the walls or free-standing display support structures are sufficient to support the weight of your displays.
You can create original or re-use content. There are many ways to deliver content to your video wall. You can have standard video formats (i.e. .mp4, .avi, .mpg, etc.) organized in a playlist and reproduced in a loop on your displays. You can also use HDMI/SDI capture cards and get multiple HDMI sources, such as cameras, laptops, PVRs, and more. Web streaming is another way that you can deliver content to your video wall. Also there is what are called Content Management Systems (CMS) that allow you to organize different content in a personalized canvas, from videos to static images, you can add weather and sports widgets and embed web content. This canvas will transfer directly to your video wall displays.
