Yealink MeetingBar A40

Yealink MeetingBar A40 is an all-in-one Android video collaboration bar designed for premium small-to-medium meeting rooms. It stitches images from two 48MP cameras to deliver a higher pixel picture, while built-in microphones and stereo speakers provide room-ready audio without extra devices.

For everyday meetings, A40 supports AI views such as IntelliFocus (up to 4 portraits), Auto Framing and Speaker Tracking, plus Picture-in-Picture and People Counting. Video output supports up to 4K 30fps and 1080p 60fps, with 6× digital zoom and an electric privacy lens cap.

MeetingBar A40 runs Android 13 and is based on Microsoft’s MDEP to support more secure, streamlined deployments. It supports native Teams, Zoom and RingCentral, and also a wired General Mode (BYOM) so it can act as USB peripherals for third-party apps. Direct connection to CTP25 enables a simplified “log in once” experience, and the device can be remotely managed and upgraded via supported management platforms.
