Execute the command: sudo nano /boot/config.txt,
Add disable_camera_led=1 to the last line,
After saving and restarting the Raspberry Pi, the Camera will work in night vision mode.
To return to normal mode, just delete disable_camera_led=1, save and restart the Raspberry Pi.
If you need to control the display mode flexibly, you can connect to the following positions through the GPIO interface of the Raspberry Pi, and switch between different modes by changing the level of the GPIO (high level is normal mode, low level is night vision mode)
