Zoom Rooms: Zoom Rooms is designed to run on hardware and appliances as a dedicated meeting environment for shared spaces (such as conference rooms), and ideal for group collaboration. Zoom Rooms is a dedicated, shared environment for communications and collaboration with a single consistent interface. This means that users know it will always work the same way regardless of which room they walk into, minimizing user error (very important when you think about meeting rooms that are shared among many different employees and their varying technical levels). Users can schedule the room using room booking tools and join their meetings with one tap. Taking Zoom Rooms outside the traditional conference room, Zoom Rooms can be deployed into open spaces as video-enabled interactive whiteboards, and even provide value add services such as digital signage, for corporate communications and branding, and room schedulers, for room booking management.
Zoom Rooms are IT-managed resources that are designed to be the only application up and running on a system. It’s also tied to a calendar resource that’s bookable by others. Zoom Rooms can leverage a variety of display, compute, audio, camera, capture, room control and touch display controller devices to join and manage meetings with integrated HD audio and video. This means that Zoom Rooms audio and video experiences can be easily deployed for phone booths, focus rooms, and huddle rooms, and customized for large boardrooms, broadcast studios, and custom training rooms.
All in all, Zoom Meetings (mobile and desktop client) and Zoom Rooms work together to greater emphasize that they are both a part of one interconnected platform, Zoom.
