Fisheye lens

A fisheye lens is an extreme wide-angle lens characterized by two primary features: short focal length (16mm or shorter) and a large field of view (180 to 270 degrees).
With its exceptionally wide field of view, a single frame captured by a fisheye lens contains remarkably rich information. Therefore, it operates in a stare-down mode without requiring rotation or scanning. Combined with its compact size and high concealment, the fisheye lens delivers unique application value across diverse fields.
