Wide Angle Lens – CCL127037MPF

CCL127037MPF-High-Resolution Wide-angle CCTV 2-Megapixel lens IR cut 1/2.7″ 120° Low F-number M12/S-mount lens (F2.0) security surveillance lens.

3.7mm M12 Wide Angle Lens for OV2710 Cameras

This 3.7mm M12 wide angle lens is designed for compact camera modules that require broad scene coverage without using an extremely short focal length. Optimized for the OV2710 2MP sensor, it provides a 120° diagonal and 97° horizontal FOV, making it suitable for smart security, embedded monitoring, and wide-area imaging applications.

With an F2.0 aperture, M12×0.5 mount, manual focus, 5.48mm BFL, and 0.3m minimum object distance, this fixed focal lens offers a practical optical configuration for compact camera integration. Its 6G construction with IR cut filter further supports a compact camera module design.

M12 Wide Angle Lens Core Highlights

• 97° horizontal FOV provides broad scene coverage for compact fixed-position cameras.
• 3.7mm fixed focal length offers a practical wide-angle configuration for close and medium-distance monitoring.
• F2.0 aperture supports a balanced optical design for everyday indoor and outdoor camera applications.
• M12×0.5 mount enables straightforward integration into compact embedded camera modules.
• 5.48mm BFL and 0.3m MOD provide useful mechanical and focusing flexibility during camera assembly.

M12 Wide Angle Lens Applications

Core Application Scenes

The 3.7mm focal length provides a useful balance between wide scene coverage and optical integration. With a 97° horizontal FOV, the lens can cover a relatively large area from a fixed installation position while avoiding the extremely short focal length required by more aggressive ultra-wide designs.

Typical applications include:

• Indoor security cameras
• Entrance and doorway monitoring
• Embedded surveillance cameras
• Smart home cameras
• IoT vision devices
• Compact monitoring modules
• Equipment-area monitoring
• Wide-area indoor imaging
• General-purpose embedded cameras

For compact security projects, this lens can be considered together with TOWIN’s Megapixel CCTV Lens and Smart Security Solutions.

Compatible Device List

Indoor Security Cameras
The 97° horizontal FOV allows a fixed-position camera to cover a relatively broad indoor area, making the lens suitable for rooms, corridors, entrances, and retail environments.

Door and Entrance Cameras
The wide-angle optical configuration helps capture people approaching an entrance while maintaining a compact camera design.

Embedded Surveillance Modules
The M12×0.5 mount and 5.48mm BFL simplify integration into small camera housings and embedded imaging equipment.

Smart Home Cameras
The combination of 2MP resolution, F2.0 aperture, and wide FOV provides a practical configuration for compact connected monitoring devices.

Industrial Monitoring Cameras
The lens can be used for general equipment-area observation where broad visual coverage is more important than precision geometric measurement.

Designed for compact wide-angle monitoring applications where broad coverage, M12 integration, and a practical 2MP optical configuration are required.

Frequently Asked Questions

Q: What is the FOV of this 3.7mm M12 lens?
A: The lens provides 120° diagonal, 97° horizontal, and 52° vertical FOV when used with the specified 1/2.7″ OV2710 configuration.

Q: Is this lens suitable for the OV2710 sensor?
A: Yes. The lens specification is designed around the OV2710 1/2.7″ 2MP sensor configuration.

Q: Is the 3.7mm M12 lens a low-distortion lens?
A: No. With distortion specified at -28%, this model should be positioned as a wide-angle lens rather than a low-distortion optical solution. For applications requiring controlled geometric accuracy, consider a dedicated Low Distortion Lens.

Q: What applications are suitable for this lens?
A: It is suitable for indoor security, entrance monitoring, embedded surveillance, smart home cameras, IoT vision devices, and general wide-area monitoring.

Q: What does the IR cut specification mean?
A: The IR cut specification indicates that an IR cut filter is incorporated into the optical configuration. It does not mean that the lens is optically corrected for both visible and near-infrared wavelengths.

Q: Can the focus be adjusted?
A: Yes. The lens uses manual focus, allowing the optical focus to be adjusted during camera assembly or installation according to the required working distance.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.3m, making it suitable for relatively close-range monitoring and wide-area imaging.

Q: How do I choose between a 3.7mm lens and a shorter focal length?
A: A shorter focal length generally provides a wider FOV, while 3.7mm offers a more moderate wide-angle perspective. The final choice should consider sensor size, installation distance, and required coverage. TOWIN’s Focal Length Calculator can help estimate the required focal length.

Optical Selection & Related Resources

Focal length and sensor size directly affect the final field of view of a camera lens. For a 1/2.7″ sensor such as the OV2710, this 3.7mm lens provides a 97° horizontal FOV, making it suitable when broad coverage is required from a compact fixed camera.

When selecting an M12 lens, it is also important to consider distortion, working distance, BFL, sensor format, and mechanical compatibility. TOWIN’s Lens Selection Guide and Sensor Guide provide additional guidance.
