Target Applications & Compatible Devices
Core Application Scenes
This 205-degree fisheye lens is specifically optimized for next-generation smart video doorbells, smart home intercoms, and compact AI security cameras where maximum visual coverage is mandatory. Its rugged all-glass build and wide-angle performance also make it highly effective for automotive surround-view systems (360° cameras), blind-spot monitoring, and drone/UAV navigation. In commercial environments, it serves as an efficient tool for machine vision inspection lines and robotics, capturing wide workspaces at an ultra-close distance of 0.1 meters without needing mechanical panning.
Compatible Device List
- Sensors: Optimized for OmniVision OV4689, fully compatible with mainstream 1/3″ and 1/3.2″ CMOS sensors.
- Hardware Modules: Fits standard M12 mount camera boards, Tuya IoT camera modules, and Hikvision/Dahua low-profile network camera boards.
- Smart Devices: Seamlessly integrates with Ring-style smart doorbells, Xiaomi ecosystem smart cameras, and custom industrial USB camera modules.
- Customization: Supports tailored IR-cut filter modifications (850nm/940nm/dual-band) to match specific day/night surveillance requirements.
“Designed for panoramic security and automotive surround-view applications.”
Frequently Asked Questions
Q: Can this M12 lens be used on a 1/2.8″ sensor camera?
A: This lens is optimally designed for a 1/3.2″ or 1/3″ format (like the OV4689). Using it on a larger 1/2.8″ sensor may cause slight dark corners or vignetting, as the image circle diameter is Φ2.9mm.
Q: What does the <-117% optical distortion mean for my image?
A: This negative value indicates a strong “barrel distortion,” which is standard and intentional for a fisheye lens to compress a massive 205-degree environment into a flat image sensor. It can be digitally corrected via software if a flat view is required.
Q: Does this camera lens include a built-in IR cut filter?
A: Yes. The component structure is 6G+IR cut, which blocks infrared light during daytime to ensure accurate color reproduction and prevents washed-out images.
Q: What is the Minimum Object Distance (M.O.D.) for this optical lens?
A: The M.O.D. is 0.1 meters (10cm). The lens can focus sharply on objects as close as 10cm away from the front element, making it ideal for close-range industrial scanning and macro vision.
Q: Is the housing made of plastic or metal?
A: The lens barrel uses high-precision metal threading (M12x0.5) paired with 6 layers of all-glass optics to ensure thermal stability and prevent focus shift in extreme automotive environments (-40°C to +85°C).
