Hello @Steven_Kami
I’m facing exactly the same issue on a yi outdoor camera since a week.
The IR lights are not working anymore (before I could see the red lights on over night as on my other outdoor camera where IR work).
I tried changing power plug, deleting camera and resetting, put it at same place as another working outdoor camera, turning off and on the IR from the app but problem remains: IR are not turning on.
Can you tell me what else I should do?
Thanks
