Profile: Topwell is engaged in the manufacture and sale of micro video borescopes. Our smallest video borescope is 4mm in outer diameter and uses an LED lamp as a light source. Our borescope accessories include tubes for gastroscopes, slim endoscopes, colonscopes and control body & LG connectors. Our wireless oral camera features a wireless long-distance high-definition video transmission and wireless control of frames of video storage. Video borescope (videoscope) is used in digital image transfers instead of transferring analog images through optical fibers. It enlarges the screen display through the PC monitor and records pictures optionally.
