Ideal for next-gen 360\u00b0 surround-view systems, autonomous mobile robots (AMR), AI-powered security cameras, and industrial imaging devices, this fisheye lens stands out as a high-performance solution among M12 Lens and CCTV Lens portfolios.<\/p>\n

Scenario-Based Functional Descriptions<\/h4>\n
209\u00b0 Ultra-Wide FOV with Low F-\u03b8 Distortion<\/h5>\n

Tailored for IMX662 sensors, this fisheye lens delivers a 209\u00b0 diagonal, 209\u00b0 horizontal, and 194\u00b0 vertical FOV, covering nearly a full hemisphere with minimal distortion (F-\u03b8 distortion <-2.9%). Compared to standard fisheye lenses with higher distortion rates, it ensures more accurate image mapping for 360\u00b0 stitching in automotive surround-view (AVM) systems and robotic navigation. The expanded FOV overlap enhances algorithm efficiency, eliminating blind spots and enabling precise environmental perception\u2014making it a top-tier M12 Lens for space-constrained, wide-coverage scenarios.<\/p>\n

5MP HD Resolution for AI-Powered Vision<\/h5>\n

As a 5MP fisheye lens, it outperforms 2MP counterparts by delivering sharp, detailed imagery for both human and machine vision. Whether used in AI obstacle detection, facial recognition, or high-precision industrial inspection, the high resolution preserves edge details even in the corners of the wide FOV. When paired with the M12 lens mount\u2019s stable optical alignment, it ensures consistent image quality, supporting reliable data input for AI models in 24\/7 surveillance and autonomous systems.<\/p>\n

F2.0 Aperture & IRCF-Free Design for IR Compatibility<\/h5>\n

The F2.0 aperture maximizes light intake, delivering clear, low-noise images in low-light environments such as night-time industrial yards, underground garages, and dimly lit warehouses. Unlike IRCF-equipped lenses, this fisheye lens is designed without an IRCF, enabling seamless integration with 850nm\/940nm IR illuminators for superior night vision. This makes it a flexible M12 Lens choice for dual-day\/night applications, including outdoor security cameras, IR-enabled robots, and covert surveillance systems.<\/p>\n

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

Equipped with the universal M12 x 0.5 (S-Mount), this fisheye lens offers effortless compatibility with a wide range of sensors, housings, and imaging modules\u2014 a key advantage of M12 Lens technology. With a Total Track Length (TTL) of 24.26mm and a fixed iris design, it balances optical performance with integration flexibility, fitting into compact devices like drone gimbals, thin-walled camera housings, and AMR sensor units. Its 0.2m minimum object distance (MOD) also supports close-range imaging needs, expanding its utility across industrial and consumer applications.<\/p>\n

FAQs<\/h4>\n

Q: How does the low F-\u03b8 distortion benefit this fisheye lens?<\/strong><\/p>\n

A: With F-\u03b8 distortion <-2.9%, this lens minimizes image warping compared to conventional fisheye lenses. This is critical for M12 Lens applications like 360\u00b0 AVM systems and robot mapping, as it reduces post-processing workload for dewarping algorithms and ensures more accurate spatial positioning of objects\u2014improving AI detection reliability and stitching quality.<\/p>\n

Q: Why is the IRCF-free design important for my application?<\/strong><\/p>\n

A: Removing the IRCF allows the lens to transmit infrared light, enabling IR night vision when paired with IR illuminators. This makes it a versatile fisheye lens for 24\/7 security cameras, outdoor AMRs, and other applications requiring both day and night imaging. Unlike IRCF-equipped lenses, it avoids color cast issues in IR mode while maintaining HD clarity.<\/p>\n

Q: Is this M12 lens compatible with my existing sensor setup?<\/strong><\/p>\n

A: Yes. The standard M12 x 0.5 (S-Mount) is universally used in industrial, automotive, and security imaging systems, ensuring seamless compatibility with most sensors (especially those matching the max \u03a63.4mm image format, such as IMX662). Its fixed iris and optimized TTL also simplify integration into existing housings without optical adjustments.<\/p>\n

Q: Can the 5MP resolution support AI object detection?<\/strong><\/p>\n

A: Absolutely. The 5MP resolution delivers crisp edge details and fine textures, even across the 209\u00b0 wide FOV. When combined with the lens\u2019s low distortion and F2.0 low-light performance, it provides high-quality image data that AI models rely on for accurate detection of pedestrians, obstacles, and small objects\u2014making it ideal for smart security and autonomous systems.<\/p>\n
