M12 F1.2 CCTV Lens Applications

Core Application Scenes

This 4mm M12 wide angle lens is designed for compact surveillance systems that need to capture a relatively broad scene from a short or moderate installation distance. Its 63° horizontal field of view provides substantially wider coverage than longer focal-length M12 lenses, making it suitable for indoor security cameras, entrances, corridors, retail areas, and localized facility monitoring.

The lens’s most distinctive optical feature is its F1.2 aperture. The relatively large aperture allows more light to reach the image sensor, making this configuration particularly useful for camera systems operating in dim indoor environments or under changing illumination. It can help maintain practical exposure levels without relying entirely on stronger artificial lighting.

The IR-corrected optical design further expands its suitability for surveillance cameras that operate across visible and near-infrared wavelengths. This makes the lens a practical option for Day & Night camera architectures where nighttime imaging may involve infrared illumination.

Its Φ22 × 25mm dimensions and 15g weight are also well suited to compact camera assemblies where optical performance must be balanced with mechanical space and module weight.

For engineers choosing between different focal lengths and sensor formats, Towin’s Lens Selection Guide can help evaluate the relationship between focal length, sensor size, field of view, and application requirements.

Compatible Device List

• 1/3″ CCTV camera modules: Designed for compatible 1/3″ image sensors in compact surveillance equipment.

• Entrance monitoring cameras: The 4mm focal length can cover a relatively broad area around doors and access points.
• Low-light surveillance cameras: The F1.2 aperture supports greater light collection when available illumination is limited.
• Day & Night camera modules: IR-corrected optics are suitable for systems operating with visible and near-infrared illumination.
• Embedded vision devices: The compact M12x0.5 mount and 15g weight support lightweight camera module designs.

For security-focused deployments, the lens can be evaluated as part of Towin’s Smart Security solutions.

Optical Selection Considerations

The 63° horizontal FOV makes this lens suitable when the camera needs wider scene coverage than a standard narrow-angle M12 fixed focal lens. At the same time, it is not an extreme ultra-wide or fisheye configuration, making it appropriate for applications requiring broad but relatively controlled framing.

The F1.2 aperture is especially relevant when lens selection is driven by illumination conditions. A fast aperture can improve the amount of light reaching the sensor, although final low-light performance also depends on sensor sensitivity, exposure settings, illumination, and image-processing algorithms.

Because the provided specifications do not include a distortion value, this product should not be marketed as a Low Distortion Lens without additional optical test data.

Engineers can use Towin’s FOV Calculator to estimate scene coverage, while the Sensor Guide can help verify sensor and lens compatibility.

For applications involving visible and near-infrared imaging, the Optical Design section provides additional background on optical design considerations.

Frequently Asked Questions

Q: What type of lens is this 4mm M12 lens?
A: It is a 4mm M12 fixed focal wide angle lens designed for 1/3″ image sensors. It features an F1.2 aperture, 63° horizontal FOV, and IR-corrected optical performance.

Q: What is the horizontal field of view of this lens?
A: The specified horizontal field of view is 63°, providing broad scene coverage for compact CCTV and embedded camera applications.

Q: Is this a fisheye lens?
A: No. Although the lens is wide angle, its specified 63° horizontal FOV does not by itself indicate a fisheye design. It is more appropriately classified as a Wide Angle Lens.

Q: What is the advantage of the F1.2 aperture?
A: The F1.2 fast aperture allows ample light to hit the image sensor, benefiting cameras in low or changing lighting.

Q: Is this lens a fixed focal lens?
A: Yes. The focal length is fixed at 4mm, so the lens belongs to the Fixed Focal Lens category rather than the Zoom Lens category.

Q: What does IR Corrected mean?
A: IR correction is designed to reduce focus shifts between visible and near-infrared wavelengths, helping maintain consistent image focus when infrared illumination is used.

Q: What sensor size is compatible with this lens?
A: The specified image format is 1/3″, so the lens is designed for compatible 1/3″ image sensors.

Q: Is this lens suitable for low-light surveillance?
A: Yes. The F1.2 aperture provides strong light-gathering capability, making the lens suitable for compact surveillance systems operating under limited illumination.

Q: What are the dimensions and weight of this M12 lens?
A: The lens measures approximately Φ22 × 25mm and weighs about 15g, making it suitable for compact and lightweight camera modules.
