The activity light below the camera lens only lights up when live video is streaming. If you are using the camera with its base, the base light will show whether the camera is receiving power.
Please make sure that the camera is directly connected to your computer; not to a USB hub or through the keyboard. If you change the USB port the camera is connected to, please select “Refresh Camera” from the Camera menu in the animation software after reconnecting the device.
If you have a HUE HD Pro Camera and need to know how to control the lights on the front of the camera, please check this separate FAQ.
