CCTV Lens – CCL1272811FMPD

CCL1272811FMPD is 3-Megapixel resolution CCTV lens 1/2.7″ 2.8-11mm manual zoom and focus lens, F1.4 φ14 Mount lens, plastic barrel, IR corrected.

1/2.7″ 3MP 2.8–11mm IR Corrected φ14 Manual Zoom CCTV Lens

This 1/2.7″ 3MP 2.8–11mm manual zoom CCTV lens is designed for compact camera systems that require a wide field of view, flexible focal-length adjustment, and IR-corrected imaging performance. With a 96°–29° horizontal FOV, F1.4 aperture, φ14 mount, manual focus and manual zoom, it provides flexible scene framing for security, monitoring, and other compact imaging applications.

IR Corrected CCTV Lens Highlights at a Glance

• 2.8–11mm manual zoom range provides flexible framing from wide-angle to narrower viewing
• 96° horizontal FOV at 2.8mm supports broad scene coverage in compact camera applications
• F1.4 aperture provides strong light-gathering capability for variable lighting conditions
• IR-corrected optical design helps reduce focus variation between visible and near-infrared wavelengths
• φ14 mount with 0.2m M.O.D. is suitable for compact camera modules and space-conscious optical integration

IR Corrected CCTV Lens Applications

Core Application Scenes

The 2.8–11mm focal-length range gives this lens a broad adjustment range for applications where the required viewing area can vary between installations. At the 2.8mm wide end, the lens provides a 96° horizontal FOV, making it suitable for monitoring relatively broad scenes. At 11mm, the horizontal FOV narrows to 29°, allowing tighter framing of subjects at greater viewing distances.

The F1.4 aperture provides a relatively large optical aperture for applications with changing illumination. Combined with the IR-corrected design, the lens can be used in camera systems that operate with both visible light and near-infrared illumination.

The manual zoom and manual focus configuration allows installers to adjust framing and focus during camera setup. Its 0.2m minimum object distance also provides useful flexibility for relatively close-range imaging compared with lenses designed only for distant surveillance.

Compatible Devices

• 1/2.7″ camera modules

Frequently Asked Questions

Q1: Is this lens a fixed focal lens or a zoom lens?
A: It is a manual zoom lens with a focal-length range of 2.8–11mm. The focal length can be adjusted manually according to the required scene coverage.

Q2: What is the horizontal field of view of this lens?
A: The specified horizontal FOV ranges from 96° to 29°, corresponding to the 2.8mm and 11mm focal-length positions respectively.

Q3: What sensor format is this lens designed for?
A: The lens is specified for a 1/2.7″ image format and supports 3MP resolution.

Q4: What is the benefit of the F1.4 aperture?
A: F1.4 provides a relatively large aperture, allowing more light to reach the image sensor. This can be useful in camera systems operating under changing or limited illumination.

Q5: What does IR Corrected mean on this lens?
A: IR correction is intended to reduce focus differences caused by different wavelengths, helping the lens maintain more consistent focus when switching between visible-light and near-infrared imaging.

Q6: Does this lens have an auto iris?
A: No. The specified iris is Fixed. The focus and zoom are also manually adjusted.

Q7: What is the minimum object distance?
A: The M.O.D. is 0.2m, meaning the specified minimum object distance is 0.2 meters.

Q8: What type of mount does this lens use?
A: This lens uses a φ14 mount. It should therefore be considered an Other Mount configuration rather than an M12, C-Mount, or CS-Mount lens.
