HUAWEI IdeaHub B2

The panel is 4K UHD with zero-gap bonding, 10-bit colour depth (8-bit + FRC), 85% NTSC gamut, 178° viewing angle and 20 touch points, with optical anti-blue light protection for long sessions.

The professional 4K camera runs an F1.8 aperture — that relatively wide aperture means better performance in dimly lit rooms — with 2x digital zoom, an 80° horizontal and 50° vertical range, and under 2% distortion.

A 550 cm³ speaker enclosure delivers 3D stereo sound — that volume figure is what separates flat audio from audio with depth, and it's what most interactive panels neglect. The system uses four units (two full-range, two high-frequency) at up to 30 W, with stereo supported. A 6-microphone array covers 10 metres across 180°.

Dual-band, dual-Wi-Fi module projection — the dual design gives more stable projection in wirelessly congested environments, a common condition in office towers. Wireless projection reaches 4K 30 fps, wired 4K 60 fps, with annotation during projection and reverse control of input devices supporting slide advance and commenting.

It runs Huawei Cloud Meeting natively on Android at 1080p via a simple QR code scan, with Windows extension through an optional OPS module (i5 or i7) for connecting to mainstream cloud meeting apps.

Writing latency is 25 ms at ±1 mm precision, converting handwriting to standard text within one second, with whiteboard content saved by QR code, email, local storage or USB drive.

Security uses a layered cloud-pipe-device-chip architecture.
