Size matters. Especially when you are designing the next generation of compact security cameras, biometric scanners, or industrial drones. You have limited space in your housing, but you can’t afford to sacrifice image quality.

Enter the JSD2112: The lens that fits in tight spaces but performs like a giant.

This isn't a lens for a hobbyist's holiday snaps. This is a precision-engineered optical component for integrators, engineers, and developers who need professional-grade vision in a tiny package.

Ultra-Compact Design (TTL: 17.41mm)

Space is premium real estate inside a PCB layout.
The headline feature of the JSD2112 is its incredibly short Total Track Length (TTL) of just 17.41mm.
Combined with a standard M12 Thread (S-Mount), this lens is ready to slot seamlessly into slim doorbells, compact dashcams, and unobtrusive security modules. It keeps your device profile low and your aesthetics sleek.

The "Big Picture" View (172°~181° Coverage)

Why use multiple cameras when one can do the job?
With an Effective Focal Length (EFL) of 2.16mm, the JSD2112 delivers a massive 181° Diagonal Field of View (approx. 172° Horizontal coverage depending on sensor crop).
It sees everything from wall to wall. But here is the magic: unlike standard fisheye lenses that bend the world into a circle, the JSD2112 boasts a Low Distortion design (<-3.17%).
This means you get the situational awareness of a fisheye, but with a natural, flatter image that makes AI detection and human monitoring much easier.

Brightness Meets Sharpness (F1.2 & 5MP)

Compact usually means dark, right? Wrong.
We packed a massive F1.2 Aperture into this small body. It allows maximum light to hit the 1/2.7" Image Circle, ensuring your sensors capture clear, noise-free images even in low-light environments.
Paired with 5MP High-Definition resolution, the JSD2112 ensures that the wide angle doesn't result in pixelated mud. You get sharp edges and distinct details across the entire frame.

Built for Machines, Not Just Photos

The JSD2112 is purpose-built for:

Smart Home Security: See the whole porch, day or night.

Automotive: Crystal clear dashcam or cabin monitoring.

Robotics: Wide obstacle detection without the bulk.
