Key Features

Everything this product brings together — built for real-world use.

Smart wireless visualizer

Models like the K6-F offer 13MP, larger-than-A3 coverage and multi-angle adjustment; a dedicated wireless receiver makes it driver-free plug-and-play, wall-mounted or mobile.

Visualizer + display sync

The B90 series is designed for teaching, connecting to interactive panels to clearly present objects, handouts and slides — a core multimedia-classroom device.

Wireless teaching system

The K7 wireless demonstrator makes hands-on technique visible, simplifying demonstration and practical training.

Multi-form lineup

Desktop, wall-mounted (B16/B11), arm-free (G15) and dual-mode (K9 HDMI/USB) visualizers cover varied classroom needs.

Portable & mobile

Use it wall-mounted or mobile; when low on battery, dock it in the wall box to charge and keep teaching uninterrupted.
