After statistics, it is found that many maintenance are based on the inspection results of the endoscope to decide whether to replace the engine.

采用的微凸镜制造工艺，大大提高了感光性和分辨率，图像的清晰度大大提高了，无法看到的黑暗的地方也能看清楚图像。存储卡替代了以前使用传统硬盘记录的方法，集拍照，录像功能为一体，检测起来更加方便，存储的能力也有所提升。

The micro convex mirror manufacturing process greatly improves the sensitivity and resolution, greatly improves the definition of the image, and can see the image clearly in the dark places that can not be seen. The memory card replaces the traditional hard disk recording method, integrates the functions of photographing and video recording, makes detection more convenient, and improves the storage ability.
