Extron ShareLink Pro vs ViewSonic AirSync

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.

ViewSonic AirSync mirrors a device screen wirelessly to ViewSonic displays through a sender app or web browser. It supports AirPlay, Google Cast, Miracast, and AirSync Sender screen sharing. Hosts can moderate requests, while multiple presenters can share screens at once; capacity varies by IFP model from four to six. Display Grouping can broadcast one display to as many as 10 ViewSonic screens on the same local network segment. AirSync supports LAN and internet connections, but Web Sender is limited to internet connections and lacks touch feedback, incoming IFP screens, pen strokes, and high-quality sharing. The Sender app offers touchback from compatible ViewBoard displays on Windows, macOS, Android, and iPad. ViewSonic describes end-to-end encryption and centralized control through ViewSonic Manager. AirSync is intended for ViewSonic displays; specified older CDE and IFP models continue with myViewBoard Display and vCast. Sessions last 180 minutes by default and can be extended twice, up to nine hours. Pricing starts at $62, and a free plan is listed.
