Fisheye Lens – CCL1202218MP

CCL1202218MP Fisheye lens HD CCTV 1/1.8″ Φ5.6 190° M12 lens 6MP F1.8 360 panoramic security surveillance

The 2.2mm focal length provides an exceptionally wide viewing range, while the 190° FOV enables a single camera to cover a very large surrounding area. The -94% distortion value is characteristic of the fisheye optical configuration and is intentionally used to achieve this extreme field of view.

The F1.8 aperture also provides a relatively large light-gathering capability for compact imaging systems, making the lens suitable for applications that may operate under indoor, shaded, or changing illumination conditions.

Engineers selecting a fisheye configuration can also use the FOV Calculator to evaluate the relationship between sensor size, focal length, and required field of view.

6MP 2.2mm 190° M12 Fisheye Lens

This 2.2mm M12 fisheye lens provides an ultra-wide 190° field of view with 6MP resolution and a fast F1.8 aperture. Its compact 26.99mm TTL, 0.1m minimum object distance, and M12×0.5 mount make it well suited for compact camera modules that require extremely broad scene coverage within limited installation space.

As a compact M12 Lens, it combines a 190° fisheye optical design with a fixed 2.2mm focal length, making it suitable for wide-area observation, embedded cameras, smart devices, and other applications where maximizing the visible scene is more important than maintaining straight-line geometry.

M12 Fisheye Lens Core Highlights

• 190° ultra-wide FOV for exceptional scene coverage
• 6MP resolution for detailed wide-area imaging
• F1.8 aperture for improved light collection
• 2.2mm fixed focal length for compact camera integration
• 26.99mm TTL with M12×0.5 mount for space-constrained devices

This combination makes the lens particularly useful when a camera needs to observe a very large area from a fixed mounting position without using a mechanical pan-tilt mechanism.

M12 Fisheye Lens Applications

Compact Wide-Area Monitoring Cameras

The 190° field of view allows this lens to capture an exceptionally broad area from a single camera position. It is suitable for compact monitoring devices installed in rooms, corridors, entrances, retail spaces, and other locations where reducing blind spots is a major requirement.

The 2.2mm focal length provides broad scene coverage while the 26.99mm TTL helps maintain a compact optical assembly. This makes the lens suitable for camera housings where installation space is restricted.

For broader security camera requirements, TOWIN also provides dedicated Smart Security solutions covering different imaging configurations and application environments.

Smart Home and Indoor IoT Cameras

This lens can be integrated into smart home cameras, indoor monitoring modules, compact IoT vision devices, and other embedded camera products that need to observe a large area from a small housing.

The 190° FOV is especially useful for applications such as room monitoring, entrance observation, pet monitoring, and activity detection, where a conventional narrow-angle lens could leave significant areas outside the camera’s view.

Robotic Environmental Awareness

The ultra-wide viewing capability can also support compact robotic platforms that need broad environmental awareness. A single camera equipped with this M12 Fisheye Lens can provide a wide surrounding view for navigation assistance, obstacle observation, and general situational awareness.

For more advanced robotic imaging systems where optical distortion, resolution, and sensor matching need tighter control, engineers can review TOWIN’s Robotics Vision solutions.

Panoramic and Immersive Imaging

The 190° field of view makes this lens suitable for panoramic and immersive imaging systems that prioritize maximum scene capture. It can be used in compact panoramic cameras, interactive devices, spatial monitoring systems, and other embedded vision equipment.

Because the lens uses a fisheye optical design, the -94% distortion is intentional rather than an optical defect. When a corrected rectilinear image is required, digital image processing can be used to compensate for fisheye distortion after image capture.

Close-Range Observation

With an M.O.D. of only 0.1m, this lens can also be used for close-range observation where the camera needs to capture nearby objects while maintaining an extremely broad field of view.

This makes it suitable for compact devices positioned close to people, objects, equipment, or indoor environments where both near-field coverage and large viewing angles are important.

Compatible Devices

This 6MP M12 Wide Angle Lens can be considered for integration with:

• Smart indoor cameras
• IoT camera modules
• Smart home monitoring devices
• Compact security cameras
• Panoramic camera modules
• Mobile robot cameras
• Indoor robotic vision systems
• Interactive vision devices
• Wide-area observation cameras
• Embedded vision platforms

The lens is specified for a 1/1.8″ sensor format and uses an M12×0.5 mount. When selecting a compatible camera module, engineers should verify the sensor format, image circle, mechanical clearance, and required FOV together.

Frequently Asked Questions

Q: What type of lens is this product?
A: This is a 2.2mm fixed focal M12 fisheye lens with a 190° field of view, 6MP resolution, and an F1.8 aperture.

Q: What is the field of view of this 2.2mm M12 lens?
A: The specified field of view is 190° diagonal, 190° horizontal, and 190° vertical, providing extremely broad scene coverage from a single camera position.

Q: Why does this lens have -94% optical distortion?
A: The -94% distortion is a characteristic of the fisheye optical design. The lens intentionally uses strong geometric distortion to achieve its extremely wide 190° field of view.

Q: Is this a low-distortion lens?
A: No. This lens is optimized for maximum field of view rather than geometric accuracy. If an application requires straight-line imaging and minimal geometric distortion, a dedicated Low Distortion Lens would be more appropriate.

Q: What sensor size is this fisheye lens designed for?
A: The lens is specified for a 1/1.8″ sensor format with 6MP resolution. Final compatibility should be confirmed according to the specific CMOS sensor and camera module.

Q: What is the advantage of the F1.8 aperture?
A: The F1.8 aperture provides relatively strong light-gathering capability, which can help maintain image brightness in indoor, shaded, or other relatively low-light environments.

Q: Is this M12 fisheye lens suitable for close-range imaging?
A: Yes. The specified minimum object distance is 0.1m, making the lens suitable for applications where the camera needs to capture nearby subjects while maintaining a very wide viewing angle.

Q: Can TOWIN customize this M12 fisheye lens?
A: TOWIN can evaluate customized requirements such as focal length, field of view, sensor format, optical performance, and mechanical dimensions. For project-specific requirements, contact TOWIN with your camera specifications and application requirements.
