1/2″ 12mm M12 Fixed Focal CCTV Lens

This 1/2″ 12mm M12 fixed focal CCTV lens combines a fast F1.4 aperture, compact 17g design, and 31° horizontal field of view for stable, detailed imaging. Its M12x0.5 mount and Day & Night capability make it suitable for compact CCTV cameras and embedded surveillance systems requiring a consistent viewing angle.

M12 CCTV Lens Core Highlights

• 12mm fixed focal length provides a consistent 31° horizontal viewing angle.
• F1.4 fast aperture supports efficient light collection in challenging illumination.
• M12x0.5 mount enables integration into compact camera modules.
• 17g lightweight construction helps minimize the optical assembly’s overall weight.
• Day & Night capability supports surveillance systems operating across changing lighting conditions.

M12 CCTV Lens Applications

Core Application Scenes

This 12mm M12 fixed focal lens is designed for camera systems that need a stable, moderately narrow field of view rather than an ultra-wide perspective. Its 31° horizontal FOV allows the camera to concentrate more pixels on a defined monitoring area, making it suitable for observing entrances, corridors, equipment zones, restricted areas, and other locations where controlled scene framing is important.

The F1.4 aperture is particularly useful for compact surveillance equipment operating under variable or reduced illumination. Combined with the Day & Night capability, the lens can support camera systems that transition between daytime monitoring and nighttime imaging without requiring a change in the optical configuration.

Its compact Φ21 × 32.8mm housing and 17g weight make it suitable for embedded camera designs where installation space and overall module weight are important. The M12x0.5 mounting interface also simplifies integration into compact camera assemblies.

For applications where the correct focal length must be selected according to sensor size, working distance, and required scene coverage, engineers can consult Towin’s Lens Selection Guide before finalizing the optical configuration.

Compatible Device List

• 1/2″ CCTV camera modules: Designed for compact surveillance cameras using 1/2″ image sensors.
• Embedded security cameras: The M12x0.5 interface and compact dimensions support space-constrained camera assemblies.
• Day & Night surveillance cameras: Suitable for monitoring equipment that needs to operate during both daytime and nighttime conditions.
• Entrance and access monitoring cameras: The 31° horizontal FOV provides more focused coverage of defined areas such as doors, gates, and access points.
• Equipment monitoring systems: The 12mm focal length can be used when the camera needs to concentrate on a specific equipment zone rather than capture an entire wide scene.
• Compact IoT vision devices: The 17g optical assembly can help reduce the weight and physical footprint of embedded imaging equipment.

For broader security applications, this lens can be evaluated as part of Towin’s Smart Security solutions, particularly where compact camera construction and consistent scene framing are required.

Optical Selection Considerations

The 31° horizontal FOV places this lens in a more focused viewing range than typical wide-angle M12 lenses. It is therefore better suited to applications where the camera is intended to monitor a defined area rather than maximize overall scene coverage.

The F1.4 aperture provides a relatively large optical opening, which can be advantageous when the camera operates under lower available light. The fixed iris also provides a straightforward optical configuration for systems with camera-side exposure control.

For engineers comparing different focal lengths and viewing angles, Towin’s Focal Length Calculator can help evaluate focal-length requirements based on the intended imaging geometry.

The Sensor Guide can also be referenced when checking the relationship between a 1/2″ sensor and the selected lens image coverage.

Frequently Asked Questions

Q: What type of lens is this 12mm M12 lens?
A: This fixed-focal M12 lens features a 12mm focal length, F1.4 aperture and 31° HFOV. It suits compact CCTV and embedded surveillance use cases.

Q: What sensor size is compatible with this lens?
A: The specified image format is 1/2″, making the lens suitable for camera systems using compatible 1/2″ image sensors.

Q: What is the field of view of the 12mm M12 lens?
A: The specified horizontal field of view is 31°. This provides a relatively focused viewing angle compared with wide-angle M12 lenses.

Q: Is this lens a zoom lens?
A: No. The lens has a fixed 12mm focal length and therefore belongs to the fixed focal lens category.

Q: What is the advantage of the F1.4 aperture?
A: The F1.4 aperture offers a large optical opening, letting more light reach the image sensor. This benefits camera systems in low or changing lighting.

Q: Is this lens suitable for Day & Night cameras?
A: Yes. The specification states Day & Night: Yes, making it suitable for surveillance systems designed to operate during both daytime and nighttime conditions.

Q: What is the mounting interface?
A: The lens uses an M12x0.5 mounting thread, a common compact interface for embedded camera modules and small surveillance cameras.

Q: What are the dimensions and weight of the lens?
A: The lens has a Φ21 × 32.8mm dimension and weighs approximately 17g, making it suitable for compact and lightweight camera assemblies.

Q: Is this lens an IR corrected lens?
A: The supplied spec confirms Day & Night capability but omits explicit IR correction details. Users should verify IR-corrected performance with Towin for their project before selecting the lens for applications requiring precise visible/NIR focus matching.
