1.5.1 C-Mount Lenses
If you use a C-mount lens, it requires a certain distance from the camera’s
imaging chip to focus the lens. Mount the supplied C-mount lens adapter /
lens ring to the camera, and then secure the lens onto the camera body.
Three types of C-mount lens rings are provided for Box Camera:

0.188 mm (transparent color) x 2

0.125 mm (black color with a glossy surface) x 2

0.254 mm (black color with a matt surface) x 2
For GV-BX140DW, a 0.125 mm is provided.
Note: The C-mount lens rings are specially designed for Box Camera.
Besides the supplied C-mount lens rings, each of these models has
already included with the necessary lens ring.
