Equipped with the industry-standard M12 x 0.5 mount— a hallmark of versatile M12 lens solutions—it integrates an IRCF (Infrared Cut-off Filter) for accurate color reproduction. Engineered for next-gen 360° surround-view systems, autonomous mobile robots (AMR), high-precision AI surveillance, and automotive imaging, this Fisheye lens delivers exceptional performance as a premium Automotive Lens and CCTV Lens option, ideal for demanding visual perception tasks.
Scenario-Based Functional Descriptions
220° Extreme Ultra-Wide Coverage, Redefine Panoramic Vision
Boasting a 220° diagonal FOV (158° horizontal, 117° vertical) when paired with the IMX335 sensor, this Fisheye lens captures a broader scope than standard 180°–210° fisheye lenses in a single frame. For automotive surround-view (AVM) systems— a key application for M12 lens in the automotive sector—and AMR navigation, the expanded FOV creates a larger overlap area for image stitching algorithms. This eliminates blind spots at vehicle corners or robot perimeters, enhances environmental mapping precision, and ensures a seamless 3D top-down view for both human operators and AI systems.
5MP Resolution & F2.3 Aperture, Sharpen Low-Light Perception
The 5-megapixel high-definition resolution delivers crisp, detailed imagery, capturing fine textures critical for AI object recognition. Complemented by a F2.3 aperture, this Fisheye lens maximizes light intake in low-illumination environments such as underground garages, night-time industrial sites, and dimly lit smart city areas. Paired with the built-in IRCF, it minimizes noise, maintains high contrast, and ensures true-to-life color reproduction—making it a dependable M12 lens for 24/7 CCTV Lens security monitoring and AI-driven obstacle detection.
M12 Mount & Fixed Iris, Seamless Integration & Stable Performance
Featuring the universal M12 x 0.5 (S-Mount), this Fisheye lens offers effortless compatibility with a wide range of 1/2.8″ sensors (supported by Max Φ6.79 image format), aligning with the flexibility of M12 lens ecosystems. The fixed iris design ensures consistent exposure in stable lighting conditions, reducing calibration complexity for embedded systems. Its structured build with IRCF enhances durability and color accuracy, making it easy to integrate into automotive external cameras, compact surveillance modules, and AMR vision systems without compromising reliability.
0.2m MOD & Optimized TTL, Versatile Close-Range Imaging
With a Minimum Object Distance (MOD) of 0.2m, this Fisheye lens excels in close-range visual tasks, such as detecting nearby obstacles for robots or capturing detailed surroundings of vehicles at low speeds. The 21.81mm Total Track Length (TTL) balances compactness and optical performance, allowing seamless integration into space-constrained housings—from drone gimbals to thin-walled security camera enclosures. As a multi-functional M12 lens, it adapts to both automotive and CCTV Lens applications while retaining ultra-wide imaging capabilities.

FAQs
Q: How does the 220° FOV of this Fisheye lens outperform standard fisheye lenses?
A: Compared to common 180°–210° fisheye lenses, the 220° FOV provides an extra “overlap buffer” for 360° stitching systems. This reduces image stretching at the edges (especially for automotive AVM and robot navigation), delivers a smoother panoramic view, and eliminates hard-to-reach blind spots—critical for high-precision environmental perception.
Q: Is this M12 lens suitable for AI-based object detection despite high distortion?
A: Absolutely. While its <-125% distortion is inherent to ultra-wide Fisheye lens design, the 5MP high resolution ensures edge pixels remain sharp. When paired with advanced dewarping algorithms, the lens provides high-quality image data, enabling AI models to detect pedestrians, obstacles, and small objects with high confidence—perfect for smart surveillance and AMR applications.
Q: What advantages does the fixed iris and IRCF bring to this Fisheye lens?
A: The fixed iris ensures consistent exposure in stable lighting environments (e.g., urban roads, indoor factories), simplifying system calibration and reducing maintenance needs. The integrated IRCF blocks infrared light during the day to maintain true colors, while supporting clear imaging in low light—making it a reliable 24/7 solution for both Automotive Lens and CCTV Lens use cases.
Q: Can this M12 lens be integrated into compact devices with its 21.81mm TTL?
A: Yes. The 21.81mm TTL is optimized for space-constrained applications. Combined with the compact M12 mount— a core advantage of M12 lens solutions—it fits seamlessly into thin-walled camera housings, small robot vision modules, and automotive side mirrors, without sacrificing ultra-wide FOV or 5MP resolution.
