Usable anywhere Small and Robust

Although small in size (22 × 22 mm), the GL-V series has approximately 3 mm thick robust body and features a twin bumper structure to protect the lens surface. The environment-resistance enclosure rating meets IP65/IP67 standards.

Small

While small, the main unit case has a robust structure approximately 3 mm thick, making it impact resistant and minimising twisting of the main body.
