The USB camera lens is made of different materials, which is why the terminal equipment will feel that the paint on the lens of the HD camera module will fall off after using the USB camera for a long time. This is because the lens frame of the USB camera manufacturer is not coated, which will cause the paint on the lens of the HD camera module to fall off. Therefore, many lenses purchased by the camera module manufacturer are made of tempered film, However, some customers buy USB cameras and use them on terminal devices for a period of time. The video is blurred. It may be that the waterproof process of the lens of the USB camera is not well done. Some customers use the lens for a period of time because some USB cameras use plastic lenses. However, if you use glass lenses, there will be no such problem.
