Why is the image of the Xiaomi Smart Camera C500 Dual black?

 If the image of the Xiaomi Smart Camera C500 Dual is black, please refer to the following details:
1. There is an obstruction in front of the PTZ camera. The infrared light directly shines on nearby objects or there is light reflection from other places, which will cause the objects or areas in the image to be white. You can turn to avoid the obstruction;
2. The fixed camera is very close to the desktop. At night, infrared light directly illuminates the nearby desktop, causing the desktop area to be white or exposed and the distant view to be black. This is a normal phenomenon. When placing the device on the desktop, try to place it on the edge of the table or use the standard bracket to raise it and place it farther away from the desktop to avoid the dark distant view and better obtain the wide-angle view of the fixed camera;
3. After inverted installation, the viewing angle of the fixed camera needs to be adjusted downward to avoid being parallel to the roof, which will cause the image to be too dark or too white, affecting the night vision effect.
