Intelligent Conference Terminal is an intelligent audio and video conferencing all-in-one device based on Android 8.1 system, supporting Ethernet/WIFI/Bluetooth connection, integrated with 4 array microphones and HD cameras. It supports HD audio and video calls and it is easy to deploy and operate, which is suitable for daily meetings, remote education, remote training and other application scenarios.
HD voice with Audio processing technology

1. Array microphone algorithm can sample and process the spatial characteristics of the sound field. It can remove the ambient background sound to the maximum extent, leaving only the required sound waves.
2. 180° intelligent sound pickup with 5 meters range, no apparent volume and sound quality decline in 3m. 3 ）48KHz uplink and 48KHz downlink audio sampling rate;
3. Perfect full-duplex so that two-way communication will no longer stuck
4. Clearer voice with intelligent dynamic noise reduction
5. the maximum instantaneous value of the speaker can be up to 92dB (0.5m), enabling the sound to be heard more clearly.

High-quality video experience, the participation will be more clear and true The 1080P high-definition camera configured by provides users with high- quality Internet video conferencing and high-definition real-time synchronized pictures. In the use of broadband networks, the video images are clear and smooth, and the voice calls are clear and natural; as clear and true as face- to-face communication.
Based on Type C connection and you can start a meeting without complex wiring and configuration, just plug and play.
