The goal of this little project is to watch wildlife, so I'm trying to turn off as many of the lights on the Pi and camera as possible.
I've disabled the main camera LED by adding
disable_camera_led=1 to my
/boot/config.txt, and that works fine.
However the IR lamps themselves also have a red light coming out of them, as if there's another red LED inside. The lamps are shining IR light which shouldn't be visible, so I am not sure what this red visible light is. A power or status indicator?
Here's a photo of what I'm talking about. The red light seems to be coming directly from the lamp, as if the IR LED is also shining visible red light.
I haven't been able to find any mention of this visible red light, nor if it is possible to turn it off. Does anyone know?
