Product Overview
Integrated AI Voice & Video Front-End Module for Digital Humans & Kiosks
The HK-M80DC integrates an 8-channel microphone array algorithm board with a 12-megapixel autofocus lens to capture crystal-clear sound and image for intelligent terminals and large screens.
- 60° narrow-angle directional sound pickup (up to 3m best range)
- 12MP Full HD resolution (4000*3000@15fps, 1080P@60fps)
- Vertical viewing angle adjustability within 45° range
- Dual outgoing cable layout (rear/bottom) with AEC speaker interface

HK-M80DC 8-Mic Broadside Array with Onboard AI Hardware DSP
Utilizes hyperdirectional microphones to capture voice accurately within a 60° pickup angle while suppressing noise from other directions. Integrated with DNN, AGC, AEC, AES, and ASR algorithm technologies for rapid AI interaction.
Ideal for AI digital human interaction, intelligent customer service, digital employees, OLED transparent screens, and indoor recording applications.
Optical Performance
12MP Full HD Autofocus Camera with 45° Tilt Adjustment
Features a 1/2.5″ CMOS sensor and 6P+IR lens delivering up to 4000*3000 high-definition resolution. The 72° wide-angle lens with 45° vertical adjustment range allows seamless installation on screens of varying heights.
- 4000*3000 @ 15fps & 1080P @ 60fps video capture
- Auto White Balance & Automatic Focus (AF) design
- 6-layer coated lens for high video clarity and smoothness
- F1.8 large aperture for superior low-light performance (0.1 Lux)
Rear and bottom outgoing cable interface design
Flexible installation options support cable exit from either the rear or bottom. Built-in USB Type-C interface requires no driver download for immediate connection, while the AEC interface supports external speakers.
Includes bottom M3 base screw holes for secure mounting on digital humans, display screens, and kiosk housings.
