In the realm of professional optics, "good enough" doesn't exist. When you are designing for industrial security, intelligent transport systems, or heavy-duty robotics, you don't need a consumer toy—you need an optical instrument.

Today, we are opening the "White Paper" on the JSD3122, a 5MP M12 lens that combines a massive aperture with a panoramic field of view to solve the toughest imaging challenges.

1. The F1.2 Aperture: Owning the Night

If there is one number you need to remember about the JSD3122, it is F/NO 1.2.

While standard board lenses struggle at F2.0 or F2.8, the JSD3122 opens wide. This ultra-large aperture allows a flood of light to hit the 1/2.7" sensor, providing superior signal-to-noise ratios in low-light environments.

The Benefit:Whether it’s a warehouse at midnight or a vehicle cabin in a tunnel, this lens delivers bright, usable 5MP images without relying on heavy digital noise reduction.

2. 181° Field of View: The "All-Seeing" Eye

Situational awareness is critical. With an Effective Focal Length (EFL) of 2.16mm, the JSD3122 delivers a stunning 181° Field of View (FOV).

The Application:This is a true fisheye capability. A single JSD3122 lens can monitor an entire intersection or room, eliminating blind spots that usually require 2 or 3 standard cameras to cover. It is efficiency through optics.

3. Precision in a Compact Package

Industrial design is about constraints. You need performance, but you have zero space.

Compact Form:With a Total Track Length (TTL) of just 17.41mm and a standard M12 thread, this lens fits into the tightest housings.

Controlled Optics: Despite the extreme 181° width, the optical distortion is managed at <-3.17%, ensuring that the data captured is consistent and reliable for edge-computing algorithms.

Summary: Not for Consumers

The JSD3122 isn't built for family portraits. It is built for:

High-end Security Surveillance

Automotive ADAS & DMS

Industrial IoT & Robotics

When your project demands 5MP resolution and F1.2 night-vision capabilities, the JSD3122 is the engineering choice that delivers clear vision when it matters most.
