What it is
The Yealink MeetingBar A40-031 is an all-in-one group video conferencing bar designed for medium meeting rooms. It combines a 48 MP dual camera with a 120° diagonal field of view, an 8-microphone array, dual 20 W speakers, and a 10.1" capacitive touchscreen into a single wall-mountable unit. It shoots up to 4K Ultra HD at 60 fps, connects over Wi-Fi 6 or Ethernet, and supports Bluetooth 5.0 for wireless device pairing.
Who it's for
This is aimed at businesses fitting out dedicated meeting rooms — typically 6 to 12 person spaces — where a single, tidy device needs to handle camera, audio, and room control without a separate PC or multiple peripherals. It suits IT managers standardising conferencing hardware across multiple rooms, and organisations running Microsoft Teams, Zoom, or similar platforms on a permanent room setup.
Why it's good
- 4K dual camera at 60 fps — a 110° horizontal field of view covers the full width of most meeting rooms without needing to pan.
- 8-microphone array — picks up voices across the room cleanly, with a 63 dB SNR keeping background noise low.
- 10.1" anti-glare touchscreen — brightness of 3,520 cd/m² means it's readable even in well-lit rooms; no squinting at a dim panel.
- Wi-Fi 6 + Ethernet + Bluetooth 5.0 — flexible connectivity options mean it works in rooms that can't easily run a cable.
- Dual HDMI outputs + USB-C + line in/out — connects to your room display and existing audio infrastructure without adaptors.
- 6x digital zoom + autofocus down to 0.1 lux — works in rooms with poor lighting, and can frame a speaker automatically.
When to choose it
Choose the A40-031 when you need a self-contained conferencing bar for a permanent meeting room installation and want 4K video without running a separate PC or codec. It's a stronger fit than entry-level bars when room size or participant count is larger, and the 8-mic array matters more than it might in a huddle space. If you only need it for a small 2–3 person huddle room, a simpler and cheaper bar will do the same job — this unit is best justified in rooms where the camera coverage and mic pickup distance earn their cost.
