Description
Eliminate blind spots entirely with this high-performance 3MP 1.65mm M12 fisheye lens. Optimized for standard 1/3″ image format sensors, it captures a true hemispherical 184° field of view (D/H/V) to deliver full 360-degree situational awareness on a single sensor housing. Featuring a bright F2.2 large aperture and a built-in IR cut filter, this premium fixed focal lens ensures exceptional low-light clarity and true-to-life daytime color rendering. Its compact M12x0.5 mount profile makes it the go-to optical component for next-generation panoramic CCTV cameras, smart doorbell ecosystems, and automotive surround-view installations.
Product Highlights
- Complete 184° Hemispherical Vision: Captures a seamless 184-degree panoramic coverage across all angles (D/H/V), transforming standard security cameras into full-room panoramic monitoring systems.
- High-Definition 3MP Optical Resolution: Tailored specifically for 3 Megapixel CMOS sensors, resolving sharp situational details and clear facial contours even at the extreme edges of the frame.
- F2.2 Large Aperture Performance: Maximizes light intake to ensure bright, high-contrast video capture under low-light outdoor settings or dimly lit indoor environments.
- Integrated Daytime IR Cut Filter: Equipped with a built-in IR cut filter to eliminate infrared color distortion, guaranteeing professional-grade color accuracy from sunrise to sunset.

Applications & Target Devices
This 3MP M12 panoramic CCTV lens is engineered to replace expensive multi-camera rigs with a single, ultra-wide optical sensor module. Its compact 23.7mm Total Track Length (T.T.L.) allows it to easily slot into space-restricted product architectures without sacrificing resolution. Thanks to the fast F2.2 aperture and custom-coated glass elements, it maintains outstanding edge-to-edge optical performance across changing environmental temperatures, preventing focal drift in outdoor deployments. The lens projects a perfect Φ3.5mm image circle on standard 1/3-inch imaging arrays, giving e-commerce and commercial security hardware providers a highly reliable, plug-and-play solution for digital panning, automatic stitching, and immersive ambient mapping.
Compatible Device List:
- Panoramic Security Cameras: Optimized for ceiling-mounted 360-degree dome cameras, warehouse surveillance pods, and office corridor monitors.

Frequently Asked Questions
Q: Why does the spec sheet state a distortion rate of <-100%?
A: In photography and optical engineering, a distortion rate of <-100% is the standard mathematical representation for a circular fisheye lens. It indicates the lens maps a wide hemispherical view (184°) onto a flat sensor surface using barrel distortion, creating the classic circular image.
Q: Can this lens be used on a 1/2.7″ or 1/2.8″ sensor module?
A: This lens is optically optimized for the 1/3″ image format (Φ3.5mm image circle). While it can physically thread into an M12 mount over a 1/2.8″ sensor, it will create distinct black borders (vignetting) around the outer frame of your screen.
Q: What is the benefit of the built-in IR cut filter?
A: The integrated IR cut filter filters out invisible near-infrared light during day-lit operations. This prevents your imagery from washing out or turning pink under direct sunlight, ensuring rich, accurate colors.
Q: Is the focus pre-set, and how do I lock it onto my camera board?
A: It is a Fixed Focal Lens with a Fixed Iris. Focus adjustment is handled during factory assembly by screwing the lens into your M12x0.5 thread holder until the image is crisp, then securing it permanently with a standard M12 lock ring or adhesive glue.
Q: What does the 0.2m M.O.D. specify for close range tracking?
A: The Minimum Object Distance (M.O.D.) of 0.2 meters (20cm) means any subject coming as close as 20cm away from the lens tip will remain in perfect, sharp focus, which is highly useful for smart doorbells where visitors stand close to the camera.
Q: Do you offer bulk customization options for specialized wavelengths?
A: Yes, we provide comprehensive OEM/ODM customization services. We can adjust the lens coatings, remove the IR filter for specialized 850nm/940nm night-vision setups, or modify the mechanical B.F.L. dimensions to fit your custom sensor housing perfectly.
