拍摄照片和视频通过USB桶孔摄像头
It is a very simple application. It displays video images from a USB bore camera (endoscope or borescope). It takes still photos and videos and store them at an internal directory. It is mainly designed for inspecting barrels of hunting guns. It can be used for inspecting other bores, burrows, holes as well.
Not all android phones and tablets support USB bore camera (endoscope). Android versions from 4.0.0 to 4.4.4, and 4.4W–4.4W.2 work best.
