CCTV Lens – CCL130812MP

CCL130812MP is 8mm Fixed iris CCTV lens, F1.2 Low F-number M12/S-Mount Lens, Megapixel resolution, IR corrected, 1/3″ Low Light Sensitive Lens.

For engineers comparing compact M12 optical configurations, Towin’s M12 Lenses category provides additional lens options for different sensor formats, focal lengths, and imaging requirements.

1/3″ 8mm M12 IR Corrected CCTV Lens

This 1/3″ 8mm M12 IR corrected CCTV lens combines an F1.2 fast aperture, 34° horizontal field of view, and compact 11g construction for space-constrained imaging systems. With an M12x0.5 mount and IR-corrected optical design, it is well suited to compact CCTV and Day & Night camera modules requiring stable imaging across changing illumination conditions.

M12 CCTV Lens Core Highlights

• 8mm fixed focal length provides a stable 34° horizontal field of view.
• F1.2 fast aperture supports efficient light collection for demanding illumination conditions.
• IR-corrected optical design helps maintain focus consistency across visible and near-infrared wavelengths.
• Compact Φ22 × 26.8mm housing simplifies integration into space-constrained camera modules.
• Only 11g in weight makes the lens suitable for lightweight embedded imaging equipment.

M12 CCTV Lens Applications

Core Application Scenes

This 8mm M12 IR corrected lens is designed for compact imaging systems that require a moderately focused field of view while maintaining reliable optical performance in both visible and near-infrared imaging conditions. Its 34° horizontal FOV provides more concentrated scene coverage than a typical wide-angle M12 lens, making it suitable for cameras monitoring a defined area rather than an entire large environment.

The F1.2 aperture is an important feature for surveillance cameras operating under low or variable illumination. A relatively fast optical system allows more available light to reach the image sensor, which can help compact cameras maintain useful image information when illumination decreases.

The lens is particularly suitable for compact security cameras, access-control cameras, indoor monitoring modules, and embedded Day & Night imaging equipment. Its Φ22 × 26.8mm dimensions and 11g weight also make it practical for camera designs where optical volume and overall module weight must be controlled.

Because the lens is explicitly IR corrected, it is better suited to imaging systems that use near-infrared illumination than a standard lens without IR correction. This characteristic can be useful in surveillance equipment that needs to maintain consistent focusing behavior when switching between visible-light and infrared-assisted imaging.

Engineers selecting an M12 lens for a specific sensor and viewing requirement can consult Towin’s Lens Selection Guide to evaluate focal length, sensor format, field of view, and application requirements.

Compatible Device List

• 1/3″ CCTV camera modules: Designed for compact surveillance cameras using 1/3″ image sensors.
• Day & Night security cameras: IR correction supports imaging systems that operate with visible light and near-infrared illumination.

• Indoor monitoring cameras: Suitable for corridors, equipment areas, storage zones, and other defined surveillance locations.
• Embedded vision modules: The compact M12x0.5 interface and 11g weight support integration into small camera assemblies.
• Low-light surveillance equipment: The F1.2 aperture is suitable for camera designs where light-gathering capability is an important optical consideration.

For security applications requiring compact optical integration, the lens can also be considered alongside Towin’s Smart Security solutions.

Optical Selection Considerations

The 8mm focal length and 34° horizontal FOV provide a relatively concentrated viewing angle for a 1/3″ sensor. This configuration can be useful when the camera must monitor a particular region without the excessive perspective coverage associated with ultra-wide-angle lenses.

The F1.2 aperture provides a fast optical configuration, while the fixed iris keeps the lens mechanically simple. Camera-side exposure processing can therefore be used to manage changing scene illumination.

The specified 0.3m M.O.D. also allows the lens to be used for relatively close-range monitoring, which can be useful for entrance, access-control, and equipment observation applications.

For calculating the required focal length based on sensor dimensions and target field of view, engineers can use Towin’s Focal Length Calculator. The Sensor Guide can also help when evaluating the relationship between sensor format and lens coverage.

Since the specification does not provide a numerical distortion value, this product should not be marketed specifically as a Low Distortion Lens without additional optical test data.

Frequently Asked Questions

Q: What type of lens is this 8mm M12 lens?
A: It is a fixed focal M12 lens with an 8mm focal length, F1.2 aperture, 34° horizontal field of view, and IR-corrected optical design.

Q: What sensor size is this M12 lens designed for?
A: The specified image format is 1/3″, making it suitable for camera systems using compatible 1/3″ image sensors.

Q: What is the horizontal field of view of the 8mm lens?
A: The specified horizontal field of view is 34°. This provides relatively focused coverage for defined surveillance areas rather than ultra-wide scene monitoring.

Q: Is the 8mm lens a zoom lens?
A: No. It has a fixed 8mm focal length, so it belongs to the Fixed Focal Lens category.

Q: What is the advantage of the F1.2 aperture?
A: F1.2 is a fast aperture that allows a relatively large amount of light to reach the image sensor. This can be beneficial for camera systems operating in low or variable illumination.

Q: What does IR corrected mean for this lens?
A: IR correction is designed to reduce focus shifts between visible and near-infrared wavelengths, helping the camera maintain more consistent focus when infrared illumination is introduced.
