Additional parameter for SYNO.SurveillanceStation.Camera, method List and camera LED

[BernoldNL]

Just sharing some information.

With the parameter 'optimize' set to true, camera_list will return much more info (tested with version 9).

Amongst that info is "whiteLedStatus", which is the LED status of a camera that supports ledCap (from get_camera_info). Value 0 means Off and 1 means On.

To turn the LED on:
api=SYNO.SurveillanceStation.DigitalOutput&method=CtrlLED&version=1&ctrlVal=true&camId=

To turn the LED off:
api=SYNO.SurveillanceStation.DigitalOutput&method=CtrlLED&version=1&ctrlVal=false&camId=
