CameraWebServer - how to configure a night mode?

[ghost]

Hi.

I'm building an ESP32 CAM based on a WROVER-E board.

I use:

• photoresistor to detect is there a night or a day
• powerful IR LED connected via external NPN transistor
• 12mm lens with IR cut filter

I want to enable night mode when the photoresistor detects night, but only when video is being streamed or a photo is being captured.
I also want to use PWM mode to control the LED power.

How can I do this using CameraWebServer?

Thanks in advance for your help.
