CCL12902918MP

The CCL12902918MP is a 2.9mm M12 wide-angle lens designed for 1/2.9″ image sensors, including the OmniVision OV4689. With a 4-megapixel resolution and an F1.8 aperture, this compact board lens provides a wide field of view while maintaining strong light-gathering capability for indoor and low-light imaging environments. The lens delivers a 138° diagonal FOV, 116° horizontal FOV, and 64° vertical FOV, making it suitable for applications that require broad scene coverage from a compact camera module.

Its standard M12×0.5 mount, fixed iris, fixed zoom, and manual focus configuration make the lens easy to integrate into embedded camera platforms and PCB-based imaging systems. The 0.2m minimum object distance also allows relatively close-range imaging compared with many standard focal-length lenses.

With its combination of 2.9mm focal length, F1.8 aperture, 4MP resolution, and ultra-wide-angle coverage, this lens is particularly suitable for compact CCTV cameras, smart security cameras, indoor monitoring devices, automotive camera modules, and other embedded vision applications.

Designed for wide-angle CCTV and compact embedded vision applications, the CCL12902918MP provides broad image coverage where camera size, viewing angle, and low-light performance are important selection factors.

For projects requiring a different sensor format, focal length, field of view, distortion specification, or optical configuration, TOWIN also provides customized M12 lens solutions and OEM/ODM optical development.

Key Features

2.9mm Wide-Angle Focal Length

The short 2.9mm focal length provides a broad viewing angle, with 138° diagonal, 116° horizontal, and 64° vertical FOV when paired with the OV4689 sensor.

F1.8 Large Aperture

The F1.8 aperture allows more light to reach the image sensor, making the lens suitable for indoor surveillance, compact security cameras, and imaging environments where available light may be limited.

4MP Resolution

The 4-megapixel optical configuration is suitable for cameras requiring clear image details for monitoring, security, and embedded vision applications.

1/2.9″ Sensor Compatibility

Designed for 1/2.9″ image sensors such as OV4689, providing a practical optical solution for compact camera modules.

Standard M12×0.5 Mount

The M12×0.5 S-mount interface supports straightforward integration with PCB cameras and compact embedded camera systems. TOWIN’s M12 lens portfolio also covers a wide range of focal lengths and FOV configurations.

0.2m Minimum Object Distance

The 0.2m M.O.D. supports relatively close-range imaging applications where the camera needs to capture objects at short distances.

Compact 6G Optical Construction

The 6G optical construction provides a compact lens configuration suitable for embedded camera designs where space and optical coverage are important.

Applications

CCTV & Security Cameras

The 116° horizontal FOV makes this lens suitable for wide-area indoor surveillance where a single compact camera needs to cover a relatively large scene.

Smart Security Cameras

The compact M12×0.5 form factor and F1.8 aperture make the lens suitable for smart security devices, indoor monitoring cameras, and embedded AI camera platforms.

Automotive Camera Modules

The 2.9mm focal length and wide FOV can be considered for compact automotive imaging modules requiring broad scene coverage, subject to the specific camera and environmental requirements.

Embedded Vision Systems

The M12 board-lens format enables integration into PCB-based camera modules used in IoT devices, intelligent cameras, and compact vision systems.

Wide-Angle Monitoring

The combination of 138° diagonal FOV and 116° horizontal FOV is suitable for applications where wide scene coverage is more important than narrow-angle magnification.

Optical Performance & Selection Considerations

Wide FOV for Broad Scene Coverage

The 2.9mm focal length produces a particularly wide viewing angle on the OV4689 sensor. This makes the lens suitable when the camera must capture a large area from a relatively short installation distance.

F1.8 for Low-Light Imaging

Compared with lenses using smaller apertures, F1.8 provides stronger light-gathering capability. This can be beneficial for indoor surveillance and other imaging environments where illumination is limited.

Distortion Characteristics

The specified optical distortion of < -57% is characteristic of this ultra-wide-angle optical design. Therefore, this lens should be selected for applications where broad image coverage is a higher priority than geometric accuracy. For measurement, dimensional inspection, or applications requiring highly accurate image geometry, consider a dedicated low distortion lens instead.

Sensor Matching

The lens is specified for the 1/2.9″ format and OV4689 sensor. Before deployment, the sensor’s active imaging area, lens mount, mechanical clearance, focus position, and required FOV should be verified to ensure system compatibility.

Frequently Asked Questions

Q: What sensor is this 2.9mm M12 wide-angle lens designed for?

A: The CCL12902918MP is designed for 1/2.9″ image sensors and is specified for sensors such as the OmniVision OV4689. The sensor’s active imaging area should be verified before final system integration.

Q: What is the field of view of this 2.9mm M12 wide-angle lens?

A: With the OV4689 sensor, the lens provides a 138° diagonal FOV, 116° horizontal FOV, and 64° vertical FOV, making it suitable for wide-area imaging.

Q: Is this lens suitable for CCTV cameras?

A: Yes. Its 2.9mm focal length, wide FOV, F1.8 aperture, and 4MP resolution make it suitable for compact CCTV, smart security, and indoor monitoring cameras where broad scene coverage is required.

Q: What does the F1.8 aperture mean for this lens?

A: The F1.8 aperture provides relatively strong light-gathering capability, which can help maintain image brightness in indoor or low-light environments. Actual low-light performance also depends on the camera sensor, exposure settings, illumination, and overall optical system.

Q: Is this a low-distortion M12 lens?

A: No. The specified optical distortion is < -57%, which reflects its ultra-wide-angle optical design. It is intended primarily for broad scene coverage rather than precision measurement. For applications requiring accurate geometry, a dedicated low-distortion M12 lens is more appropriate.

Q: What mount does this lens use?

A: The lens uses a standard M12×0.5 mount, commonly used for compact PCB cameras, embedded vision modules, CCTV cameras, and other small camera systems.

Q: What is the minimum object distance of this lens?

A: The specified M.O.D. is 0.2m, meaning the lens is designed for imaging objects from approximately 0.2m under the specified focusing configuration. Actual focusing performance may vary depending on the camera module and mechanical setup.

Q: Can TOWIN customize a similar wide-angle M12 lens?

A: Yes. TOWIN supports OEM/ODM optical development and can evaluate requirements such as sensor format, focal length, FOV, aperture, distortion, working distance, resolution, and mechanical dimensions to develop a customized M12 lens solution.
