Issues controling exposure for logitech c920 camera raspberry pi 5

General

Hi everyone, hope you are doing well.
I’m using a logitech c920 webcam with the raspberry pi for a fire detection system. In order for it to work propperly I need to turn down expoure so the fire doesn’t look all white.

I was able to adjust the exposure using the raspi cam, but require the use of a USB webcam.

#Camera Controls
            controls = {'FrameRate': 25, "AeEnable": False,"ExposureTime": 5000}

thanks in advance
