Target Applications & Compatible Devices
Core Application Scenes
This ultra-HD 12MP fisheye lens is built for professional-grade panoramic surveillance and high-end industrial automation where maximum spatial data must be captured with absolute clarity. It is uniquely suited for 360-degree ceiling dome security cameras in expansive indoor environments like airport terminals, retail malls, and warehouse logistics hubs. Furthermore, its rugged build, IR corrected design, and minimal 0.1m object distance make it highly effective for intelligent transportation systems (ITS) monitoring multi-lane intersections, drone-based aerial mapping, and high-precision machine vision sorting lines.

Frequently Asked Questions
Q: Can this lens be used with standard 1/2.8″ or 1/3″ sensors?
A: Yes, but because it is designed for a large 1/1.7″ sensor (Φ5.6mm image circle), using it on a smaller 1/2.8″ or 1/3″ sensor will crop the image, resulting in a narrower field of view than the rated 185°.
Q: Why is an IR corrected lens crucial for this model?
A: Visible light and infrared light have different wavelengths, which usually cause them to focus at different points (focus shift). Our IR corrected lens utilizes specialized extra-low dispersion glass to ensure both day and night light focus on the exact same sensor plane, keeping night vision perfectly sharp.
Q: What does the <-97% optical distortion specify?
A: This value represents the barrel distortion curve required to create a full 185° panoramic image. The distortion is optically controlled and highly uniform, allowing modern camera firmware or VMS software to easily de-warp the circular image into a flat, natural perspective.
Q: Does this 12MP lens have a manual focus adjustment?
A: The lens barrel uses a precise M12x0.5 thread interface. You adjust the focus manually during installation by rotating the lens within the mount, and then lock it into position using a lock ring or set screw.
Q: Is this lens suitable for outdoor environments with severe temperature fluctuations?
A: Yes. Built with premium all-glass optical elements and a rugged housing, this lens maintains excellent thermal stability. It prevents the focal drift and image degradation commonly seen in plastic alternatives under direct sunlight or extreme cold.
