Equipped with the industry-standard M12 x 0.5 mount<\/strong>\u2014 a staple for compact embedded vision solutions\u2014it integrates an IRCF<\/strong> (Infrared Cut-off Filter) for accurate color reproduction. Engineered for next-gen 360\u00b0 surround-view systems (AVM), autonomous mobile robots (AMR), high-precision AI security cameras, and automotive perception modules, this lens stands out as a premium choice for both Automotive Fisheye Lens and AI-Powered CCTV Lens applications.<\/p>\n

Scenario-Based Functional Descriptions<\/h4>\n
199\u00b0 Ultra-Wide FOV for Comprehensive Environmental Coverage<\/h5>\n

Boasting a 199\u00b0 diagonal FOV (199\u00b0 horizontal, 90\u00b0 vertical) when paired with the AR0821 sensor, this fisheye lens captures an expansive visual range that surpasses standard 180\u00b0 lenses. In automotive surround-view (AVM) systems\u2014 a key use case for Automotive Fisheye Lens\u2014and AMR navigation, the wide FOV creates ample overlap for image stitching algorithms, minimizing distortion at edges and ensuring seamless 3D environmental mapping with zero blind spots. For smart city surveillance, it enables single-lens coverage of large areas, reducing the number of cameras needed for full-perimeter monitoring.<\/p>\n

8MP High Resolution for Precision AI Object Detection<\/h5>\n

With 8 Megapixel HD resolution, this lens delivers sharp, detailed imagery that outperforms lower-resolution alternatives. Whether used in AI Security Lens setups for identifying fine features (e.g., license plates, facial details) or in industrial robot vision for recognizing small components, the high resolution ensures AI models receive high-fidelity data. Even at the extreme edges of the 199\u00b0 FOV, the lens maintains clarity, supporting confident detection of pedestrians, obstacles, and critical objects in complex scenes.<\/p>\n

F2.6 Aperture & IRCF for Balanced Day-Night Performance<\/h5>\n

The F2.6 aperture optimizes light intake for consistent performance in semi-low-light environments, such as dusk, dawn, or indoor warehouses with dim lighting. Combined with the built-in IRCF, the lens achieves accurate color balance during daytime while reducing glare and noise\u2014 a crucial advantage for 24\/7 CCTV Lens applications. Unlike lenses without IRCF, it avoids color distortion, ensuring reliable image data for both human monitoring and AI analytics across varying lighting conditions.<\/p>\n

M12 Mount & Optimized TTL for Versatile Integration<\/h5>\n

Featuring the universal M12 x 0.5 mount\u2014 the gold standard for compact vision modules\u2014this lens enables seamless integration with a wide range of sensors, housings, and devices. With a Total Track Length (TTL) of 22.98mm and a fixed iris design, it balances structural stability and space efficiency, making it suitable for space-constrained setups like drone gimbals, thin-walled automotive cameras, and compact AMR sensor modules. The 0.2m minimum object distance (MOD) further expands its utility for close-range vision tasks, such as robotic pick-and-place operations.<\/p>\n

FAQs<\/h4>\n

Q: How does the 199\u00b0 FOV enhance 360\u00b0 surround-view systems (AVM)?<\/strong><\/p>\n

A: The 199\u00b0 FOV provides a larger overlap area between adjacent lenses compared to standard 180\u00b0 fisheye lenses. This overlap simplifies stitching algorithms, reduces edge distortion in the final 3D top-down view, and ensures full coverage of vehicle corners\u2014 a critical advantage for Automotive Fisheye Lens applications\u2014enhancing driver safety and parking precision.<\/p>\n

Q: Can this lens support AI obstacle detection despite high distortion?<\/strong><\/p>\n

A: Yes. While the lens has a distortion rate of <-98%, its 8MP high resolution maintains edge clarity, and the distortion is predictable and easy to correct via dewarping software. The high-fidelity image data post-correction enables AI models to detect and classify obstacles, pedestrians, and small objects with high accuracy, making it ideal for AI Security Lens and AMR vision systems.<\/p>\n

Q: What is the benefit of the built-in IRCF?<\/strong><\/p>\n

A: The IRCF blocks infrared light during daytime, preventing color distortion and improving image contrast. This ensures consistent, true-to-life color reproduction for both human monitoring and AI analytics. For applications requiring IR night vision, customized versions without IRCF or with dual-filter switchers are available to pair with 850nm\/940nm IR illuminators.<\/p>\n

Q: Is this lens compatible with most compact vision devices?<\/strong><\/p>\n

A: Absolutely. The industry-standard M12 x 0.5 mount ensures compatibility with a wide range of sensors, camera housings, and compact devices (e.g., AMRs, drones, automotive AVM modules). The 22.98mm TTL and fixed iris design further optimize it for space-constrained installations without compromising optical performance.<\/p>\n
