Let’s be clear right off the bat: The JSD3122 is not for your vacation selfies.

This isn't a lens designed to make food look tasty on Instagram. This is a heavy-duty, industrial-grade optical instrument designed to see what others miss. Whether it's high-end security surveillance, automotive sensing, or complex IoT monitoring, the JSD3122 is built to challenge the limits of what an M12 board lens can do.

Here is why this 5MP powerhouse is rewriting the rules of industrial vision.

1. 181° of "See-Everything" Vision

Most lenses give you a slice of the world. The JSD3122 gives you the whole pie. With a massive 181° Field of View (FOV) and an Effective Focal Length (EFL) of 2.16mm, this lens provides a true panoramic fisheye experience.

Why does this matter? Because in security and industrial monitoring, blind spots are liabilities. A single JSD3122 can replace multiple standard cameras, covering an entire room, parking lot, or warehouse floor in a single, high-resolution 5MP frame.

2. F1.2: A Monster in the Dark

In the world of optics, the F-number is the gatekeeper of light. While standard lenses sit at F2.0, the JSD3122 boasts a wide-open F/NO 1.2 aperture.

This is a game-changer for low-light performance. It allows significantly more light to hit the 1/2.7" image sensor, meaning your system can capture crisp, usable footage in near-darkness without relying on grainy digital gain. When the lights go out, the JSD3122 keeps working.

3. Precision Engineering (Distortion <-3.17%)

Fisheye lenses are notorious for chaotic image bending. However, the JSD3122 keeps things controlled. With optical distortion held to <-3.17%, it strikes a balance between ultra-wide coverage and image usability.

Packed into a compact TTL (Total Track Length) of just 17.41mm, this M12 lens is a marvel of miniaturization. It fits where bulky DSLR lenses can't, making it the perfect choice for discreet security domes, drone bellies, and compact industrial sensors.

The Verdict

The JSD3122 is a specialized tool for professionals. It combines the width of a fisheye with the brightness of a prime cinema lens.

If you are building the next generation of smart security or industrial cameras and need a lens that offers 5MP resolution and unrivaled night vision, stop looking. You’ve found it.
