Description

From the listing uploaded by “appupdater”.

EMS Express Mobile Software - Quantum Ultra is an application designed to provide intuitive user control of Quantum Ultra videowall processors from Android devices. The software combines the freedom of wireless control with an easy to use application operated with familiar finger gestures, such as tap, drag and drop, swipe, and pinch/stretch. It facilitates preset selection, window size and position, source selection, and other common operational tasks, and can work in tandem with VCS and a control system. Up to 10 users can control one or more videowalls. Separate User, Designer, and Administrator credentials define operational roles. EMS-Quantum Ultra is ideal for use with systems requiring one or more points of control through a user-friendly interface. EMS-Quantum Ultra can be used in any application that requires mobile, wireless control of a videowall for operational use. This includes corporate conference rooms, command and control centers, network operations hubs, or other applications that would benefit from intuitive control, either single-point or multi-point. A LinkLicense® upgrade for the Quantum Ultra, LinkLicense for EMS-Quantum Ultra, is required to enable communication between EMS and the processor. Familiar finger gestures facilitate easy and intuitive control of videowalls. Drag and drop enables quick changes between presets and source selection within windows. Effortlessly resize windows using familiar two-finger pinch and stretch actions. To access each videowall in the system, swipe to switch between canvases.
