			The same function is available on the gamepad (red button)

	When recording, there is an LED in the LED-band that will illuminate (orange) for every camera that is recording. If the camera is not found or has failed, the corresponding LED will not illuminate.		When recording, there is an LED in the LED-band that will illuminate (orange) for every camera that is recording.
