Except the basic function of whiteboard, this model also has built-in microphone and camera, so we do not need to add more external equipment when we want to take a photo or record the voice. The screen is still high definition 4K LCD/LED screen, and with the 4mm tempered glass it can protect the LCD panel from malicious damage, as well the anti-glare function can help us to see more clear without dizziness. The microphone is 4 array which can upgrade to 6 or 8 array, and the camera is standard 800W which can upgrade to 1200W according to your needs.
