Trouble shooting:
1. The preview image is completely white but the fps is normal.
The camera is over exposed, please reduce the exposure and/or gain.
Keep in mind that you can only see brightness without lens or scope
2. The preview screen is black and the fps is “0”.
Please try to slow down the capture speed by reducing the “Turbo USB”.
Also try connecting the camera to your PC directly without a USB hub or
extender if reducing “Turbo USB” still does not work.
