Extron ShareLink Pro is an app for sharing images, video, and device screens wirelessly to a room display through an Extron ShareLink Pro presentation system. The system can show up to four pieces of content at once. Collaboration mode allows any user to share, while Moderator mode gives a designated moderator control over who presents. The app supports Apple and Android smartphones and tablets; the system also works with macOS and Windows computers. Android devices connect through the existing Wi-Fi network. Extron says content sent between devices and the system is encrypted, and a Welcome Screen Display ID Code helps direct content to the intended display. Extron GVE can centrally manage setup, configuration, and firmware updates across multiple units. The app is free, but requires an Extron ShareLink Pro presentation system. It is listed for iOS, Android, macOS, web, and Windows. Extron lists 24-hour technical support at its Anaheim worldwide headquarters and says product pricing information is available to Extron Insider customers.
