CCTV Lens – CCL122514MP

CCL122514MP is 25mm Megapixel CCTV lens, F1.4 M12/S-mount lens with Low F-number (Fast Lenses), IR corrected, 1/2″ Low Light Sensitive Lens.

For other compact focal-length configurations, engineers can explore Towin’s M12 Lenses range when selecting an optical assembly for a specific sensor and viewing requirement.

1/2″ 25mm M12 IR Corrected Fixed Focal CCTV Lens

This 1/2″ 25mm M12 IR corrected fixed focal CCTV lens is designed for focused surveillance imaging where a narrower 15° horizontal field of view is preferred over wide-area coverage. With an F1.4 aperture, compact Φ21 × 30.1mm housing, and lightweight 13g construction, it provides a practical optical solution for compact Day & Night and embedded CCTV camera systems.

M12 CCTV Lens Core Highlights

• 25mm fixed focal length provides focused imaging for defined monitoring areas.
• 15° horizontal FOV supports narrow-angle, target-oriented surveillance.
• F1.4 aperture provides strong light-gathering capability for low-light imaging.
• IR corrected optical design supports more consistent imaging across visible and near-infrared wavelengths.
• 13g compact construction helps minimize the size and weight of embedded camera modules.

M12 CCTV Lens Applications

Core Application Scenes

This 25mm M12 fixed focal lens is designed for surveillance applications where the camera needs to concentrate on a specific target area rather than capture a broad scene. Its 15° horizontal field of view provides a relatively narrow perspective, making it suitable for monitoring defined zones such as entrances, access points, equipment areas, building perimeters, and distant indoor targets.

The 25mm focal length can provide greater subject framing at a given camera-to-target distance than shorter focal-length M12 lenses. This makes the lens useful when a compact camera must observe a specific area without relying on a large conventional C/CS-mount optical assembly.

The F1.4 aperture is another important feature for this type of application. When available illumination decreases, the large aperture can help the camera receive sufficient light for image capture. Combined with the IR-corrected design, the lens is suitable for imaging systems that operate across visible and near-infrared wavelengths.

For engineers selecting between different focal lengths according to sensor size, target distance, and required image coverage, Towin’s Lens Selection Guide provides a useful reference for optical selection.

Compatible Device List

• 1/2″ CCTV camera modules: Designed for compact camera systems using compatible 1/2″ image sensors.
• Access control cameras: The 15° FOV can concentrate imaging on entrances, gates, doors, and other controlled areas.
• Perimeter monitoring cameras: The 25mm focal length is suitable for observing defined areas along a building or facility perimeter.
• Equipment monitoring systems: Useful for cameras dedicated to specific machinery, cabinets, entrances, or restricted zones.
• Day & Night surveillance cameras: IR correction supports applications where near-infrared illumination may be used for nighttime imaging.
• Compact embedded camera modules: The Φ21 × 30.1mm dimensions and 13g weight are suitable for space- and weight-constrained camera designs.

For security applications requiring focused monitoring rather than panoramic coverage, this lens can be integrated into Towin’s Smart Security solutions.

Optical Selection Considerations

The 15° horizontal FOV is a key differentiating feature of this lens. Compared with wide-angle M12 optics, it captures a narrower scene and can therefore be considered when the camera position and target area are relatively well defined.

The 25mm focal length should be selected together with the camera’s sensor size and installation distance. A longer focal length generally produces a narrower field of view, so engineers should verify the expected image coverage before installation.

Towin’s Focal Length Calculator can be used to evaluate focal-length requirements based on target distance and desired framing. The FOV Calculator can also help estimate the horizontal and vertical scene coverage for a specific camera configuration.

The lens is explicitly specified as IR Corrected, making it different from a standard visible-light-only fixed focal lens. For more information about optical characteristics and lens engineering considerations, engineers can also consult the Optical Design section of Towin’s Knowledge Center.

Frequently Asked Questions

Q: What type of lens is this 25mm M12 lens?
A: It is a 25mm fixed focal M12 lens designed for focused surveillance imaging. It features a 15° horizontal field of view, F1.4 aperture, and IR-corrected optical performance.

Q: What is the field of view of this 25mm M12 lens?
A: The specified horizontal field of view is 15°. This relatively narrow viewing angle is suitable for monitoring a defined target area rather than providing wide-area coverage.

Q: Is the 25mm M12 lens a zoom lens?
A: No. It has a fixed 25mm focal length and a fixed iris, so it belongs to the Fixed Focal Lens category.

Q: What does IR Corrected mean?
A: IR correction is designed to reduce optical focus shifts between visible and near-infrared wavelengths. This helps the lens maintain more consistent imaging performance when the camera uses infrared illumination.

Q: What cameras are compatible with this lens?
A: The lens is specified for a 1/2″ image format and uses an M12x0.5 mount. It is suitable for compatible compact CCTV, Day & Night, and embedded camera modules.

Q: Is this lens suitable for wide-area surveillance?
A: Its 15° horizontal FOV is relatively narrow, so it is better suited to focused monitoring of a defined area than to applications requiring maximum scene coverage.

Q: What are the dimensions and weight of the lens?
A: The lens measures approximately Φ21 × 30.1mm and weighs about 13g, making it suitable for compact and lightweight camera assemblies.

Q: Can this lens be used for Day & Night imaging?
A: Yes. Its IR-corrected optical design is suitable for camera systems that operate with visible and near-infrared wavelengths, including applications using infrared illumination.
