Every Xtreme capture card works on its own in a standard PC — no VSN chassis, no wall controller required, just a single machine and the software you already use.
One Piece of Software, Every Wall.
VigiControl manages layout, sources and access control across every VSN-based video wall — from a single meeting room screen to a distributed multi-site command centre.
Video Walls Built for Connected Operations
A clear transformation is underway: video walls are no longer just displays. They're becoming the visual core of modern workflows — linking dashboards, live data, applications, operator workstations, and distributed teams. EMS Imaging delivers the control and processing technology that manages what appears, where it appears, and how users interact with it. Smarter control. Faster decisions. Connected operations.
