Its built-in camera provides 120° angle of view, which is usable in a small meeting room. Meanwhile, it has additional interfaces for expanding PTZ camera to support a medium or large meeting room. The extended and built-in cameras can work together to achieve dual-camera intelligent tracking and fast image switching. AI technology that includes multi-modal information such as images and sounds frees users from the remote controller, realizing a more intelligent experience where 16 microphones capture the sound of all the people in the meeting room in real time and the cameras detect the meeting room environment and the state of attendees.
