Introduction
AI intelligent voice interactive camera
The K100 is a dedicated voice front-end hardware solution powered by a 4-element directional MEMS microphone array and an ultra-high-definition 12MP camera. Utilizing super-directional beamforming technology, it precisely captures speech within a 60° target angle while effectively suppressing off-axis ambient noise. Integrated with DSP algorithms including DNN noise reduction, AEC (Acoustic Echo Cancellation), AES, AGC, and ASR pre-processing, the driverless plug-and-play module is ideal for digital human interaction, smart customer terminals, education recording, and video conferencing.
Applications
- Digital human / Virtual human interaction
- Intelligent customer service / Digital employee
- Live broadcast / Webcast
- Video conference / Video call
- Government equipment / Education recording / Medical video
60° Directional Spatial Filtering
By leveraging advanced 4-element microphone array spatial filtering, K100 forms a precise 60-degree directional pickup beam in front of the screen while actively suppressing off-axis noise and speech from surrounding environments.
Specifications and parameters
Integrated with an onboard 8-channel array algorithm processing chip, offering AEC (Acoustic Echo Cancellation), Beamforming, Directional Pickup, Noise Suppression, and AGC (Automatic Gain Control). Designed to filter ambient noise outside the target pickup zone. Paired with a 12MP autofocus camera for seamless human-computer interaction and smart display terminals.
