Fisheye Lens – CCL118024MP

CCL118024MP Fisheye CCTV HD lens IR corrected 1/1.8″ Φ5.4 M12 lens 184° 3MP F2.3 security surveillance

2.4mm 3MP M12 Fisheye IR Corrected Lens

This 2.4mm M12 fisheye lens is designed for compact imaging systems that require an extremely wide field of view. Featuring a 1/1.8″ image format, 184° FOV in diagonal, horizontal, and vertical directions, and 3MP resolution, it provides an ultra-wide imaging solution for applications where maximum scene coverage is more important than geometric image linearity. The -99% distortion is characteristic of its fisheye optical design, allowing the lens to capture an exceptionally broad scene from a compact camera position. With a fixed F2.3 aperture, 0.1m minimum object distance, 24mm TTL, and IR-corrected optical performance, this M12 lens is suitable for compact smart cameras, panoramic monitoring, embedded vision devices, and other space-constrained imaging systems.

M12 Fisheye Lens Core Highlights

• 184° Ultra-Wide FOV: Delivers 184° diagonal, horizontal, and vertical coverage for maximum scene capture.
• 2.4mm Fisheye Design: The ultra-short focal length supports extremely wide-angle imaging from compact camera positions.
• 3MP Resolution: Provides suitable image detail for embedded monitoring and wide-area vision systems.
• Compact M12 Mount: M12x0.5 mounting enables integration into small camera modules and embedded imaging equipment.
• IR-Corrected Optics: Supports more consistent imaging performance across visible and infrared wavelengths.

M12 Fisheye Lens Applications & Compatible Devices

Panoramic and Wide-Area Monitoring

The 184° field of view makes this M12 fisheye lens suitable for applications that need to observe a very large area from a single camera position. The lens can capture a broad scene without requiring multiple conventional narrow-angle lenses, making it useful for compact panoramic and wide-area monitoring devices.

Compatible devices:

• Panoramic security cameras
• Wide-area monitoring cameras
• Indoor smart cameras
• Compact surveillance modules
• Embedded monitoring systems

Practical value: The extremely wide FOV can reduce blind spots and increase scene coverage when camera installation space or the number of cameras is limited.

Smart Home and IoT Cameras

The compact 24mm TTL and M12x0.5 mount make this lens suitable for embedded camera designs where optical coverage and mechanical space are both important. Its 0.1m M.O.D. also supports relatively close-range scene capture.

Compatible devices:

• Smart home cameras
• IoT vision devices
• Indoor monitoring cameras
• Compact wireless cameras
• Smart building sensors with imaging modules

Practical value: A single ultra-wide-angle camera can monitor a large nearby area while maintaining a compact camera form factor.

Panoramic and Immersive Imaging

With 184° coverage across D/H/V specifications, this 2.4mm fisheye lens is designed for applications requiring an extremely broad perspective. The intentional high fisheye distortion can be suitable for panoramic image processing, immersive viewing, and software-based image correction.

Compatible devices:

• Panoramic imaging modules
• Immersive vision cameras
• 360°-class imaging systems
• Virtual-tour imaging equipment
• Wide-angle recording devices

Practical value: The fisheye optical architecture maximizes the amount of scene captured by the image sensor, providing useful source imagery for downstream dewarping and panoramic processing.

Embedded Vision Systems

The M12x0.5 mount, fixed F2.3 aperture, and compact 24mm TTL make the lens appropriate for embedded vision equipment where a large field of view is required within a small optical package.

Compatible devices:

• Embedded vision modules
• Compact inspection cameras
• Edge AI cameras
• Robotics perception modules
• IoT imaging devices

Practical value: The ultra-wide optical configuration enables broad scene acquisition without requiring a physically large lens assembly.

For systems that require precise field-of-view calculations, engineers can also use the TOWIN FOV Calculator to evaluate lens and sensor combinations.

Optical Design Considerations

Unlike a low-distortion lens, this product intentionally uses a fisheye optical architecture with -99% distortion to achieve an exceptionally wide 184° field of view. Therefore, it should be selected when scene coverage is the primary requirement rather than straight-line preservation.

For engineers evaluating sensor compatibility, the 1/1.8″ image format should be matched with the camera sensor before final lens selection. TOWIN’s Sensor Guide provides additional information for evaluating sensor and lens compatibility.

The fixed 2.4mm focal length provides a dedicated ultra-wide viewing configuration, while the F2.3 aperture provides a fixed optical configuration suitable for compact camera integration. For applications requiring a different balance between FOV, distortion, resolution, and sensor format, TOWIN can provide additional lens selection and optical customization support.

Frequently Asked Questions

Q: What type of lens is this?
A: This is a 2.4mm M12 fisheye lens with a 184° field of view and -99% distortion, designed for extremely wide-area imaging.

Q: Why does this lens have -99% distortion?
A: The high negative distortion is a characteristic of the fisheye optical design. It allows the lens to achieve an exceptionally wide 184° field of view rather than maintaining rectilinear image geometry.

Q: Is this a wide-angle M12 lens?
A: Yes. With a 184° FOV, it is an ultra-wide-angle M12 lens designed for applications requiring maximum scene coverage.

Q: What sensor size is this lens designed for?
A: The specified image format is 1/1.8″, with an image circle specification of Φ5.4. The actual camera sensor should be checked for optical compatibility before integration.

Q: Is the lens IR corrected?
A: Yes. The lens is specified as IR Corrected, making it suitable for imaging systems that require improved optical consistency across visible and infrared wavelengths.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m, allowing the lens to capture relatively close scenes.

Q: What mount does the lens use?
A: It uses an M12x0.5 mount, making it compatible with compact M12 camera modules and embedded imaging systems that support this mounting interface.

Q: Can TOWIN customize this type of fisheye lens?
A: TOWIN can evaluate customized optical requirements such as focal length, sensor format, field of view, distortion characteristics, and mechanical configuration. For project-specific requirements, contact TOWIN through the Contact page.
