The Atlona AT-VDL-10, AT-VDL-50, and AT-VDL-250 are convenient and affordable upgrade license options for the Atlona Velocity Control System that add the flexibility of using BYOD mobile devices or PCs as user interfaces for AV control. They enable up to 10, 50, or 250 simultaneous devices per Velocity Control Gateway processor, with the same AV and room control functions as the Velocity Touch Panels. Access to the Velocity Control System is simple and straightforward through the web browser or app. The AV control GUI is automatically delivered by the Velocity Control Gateway, optimized to the resolution and aspect ratio of the user device.
