The status LED option is only available to Reolink battery-powered cameras. And it
has two working modes.
Standby Mode: The camera is in the power-saving mode; there is no live view
or video recording.
Working Mode: The camera is running at full capacity. It enters the working
status when someone is accessing the camera via Reolink software or the PIR
motion sensor detects movement.
