CCTV Lens – D14281212716P2M

D14281212716P2M is 2.8-12mm IR corrected CCTV lens, 1/2.7″ wide-angle to telephoto zoom lens, P-Iris, F1.6 Φ14 Mount lens, 2-megapixel resolution.

2.8–12mm 2MP Φ14 Motorized Zoom IR Corrected CCTV Lens

This 2.8–12mm motorized zoom lens is designed for 1/2.7-inch 2MP camera systems requiring wide-area coverage, electronic zoom and focus, and reliable day/night imaging. With a P-Iris, step-motor-driven zoom and focus, and IR-corrected optical design, it provides flexible imaging performance for professional CCTV and intelligent surveillance applications.

Motorized Zoom IR Corrected CCTV Lens Core Highlights at a Glance

• 2.8–12mm motorized zoom: Provides a flexible focal-length range from very wide scene coverage to tighter target framing.
• 114°–31° horizontal FOV: The wide 2.8mm setting supports broad-area surveillance, while 12mm provides a narrower viewing angle.
• P-Iris control: Provides more precise aperture control for applications where exposure and image quality need to be managed across changing lighting conditions.
• Step-motor zoom and focus: Enables electronic lens adjustment for remotely controlled surveillance systems.
• IR-corrected optical design: Supports improved focus consistency when the camera operates across visible and near-infrared wavelengths.

Motorized Zoom IR Corrected CCTV Lens Applications

The 2.8–12mm focal-length range combines a very wide viewing angle with moderate telephoto coverage. At 2.8mm, the lens provides a 114° horizontal FOV, making it suitable for broad scene observation. At 12mm, the FOV narrows to 31°, allowing the same camera system to concentrate on a smaller area or selected target.

The lens uses step motors for both zoom and focus, so focal-length and focus adjustments can be controlled electronically. This configuration is useful for intelligent CCTV systems, remote surveillance platforms, and camera modules where physical manual adjustment is inconvenient.

The P-Iris provides controlled aperture adjustment rather than a simple fixed aperture. Combined with the F1.6 maximum aperture, it provides flexibility when managing exposure and depth-of-field characteristics under different lighting conditions.

The lens is also specified as IR corrected. This is particularly relevant for day/night surveillance systems because optical performance needs to remain stable when near-infrared illumination is introduced. For more information about infrared optical considerations, see TOWIN’s IR Corrected Lens category.

Core Application Scenes

• Wide-area security monitoring: The 114° horizontal FOV at 2.8mm helps cover large scenes with fewer blind areas.
• Day/night surveillance: The IR-corrected design supports imaging systems operating across visible and near-infrared wavelengths.
• Intelligent CCTV: Motorized zoom and focus enable electronic adjustment according to monitoring requirements.
• Commercial and building security: The 2.8–12mm range can cover entrances, halls, retail areas, and other changing surveillance scenes.
• Perimeter and facility monitoring: The 12mm end provides a narrower viewing angle for more concentrated observation.

Designed for professional CCTV and intelligent surveillance applications where wide-angle coverage, motorized lens control, P-Iris adjustment, and IR-corrected imaging are required.

Compatible Device List

• 1/2.7-inch 2MP security cameras
• Motorized zoom CCTV cameras
• Day/night surveillance camera modules
• Intelligent IP surveillance systems
• Remote-controlled security cameras
• Customized camera platforms using a Φ14 optical interface

Because the lens uses a Φ14 mount rather than a standard C- or CS-mount interface, mechanical compatibility should be confirmed during camera integration. TOWIN provides additional Other Mount Lenses for specialized camera and optical assemblies.

Wide-Angle to Medium-Telephoto Zoom Coverage

The 2.8–12mm range provides approximately a 4.3× focal-length ratio. The wide end is optimized for broad scene coverage, while the longer focal length provides a more concentrated view of selected areas.

When selecting the working focal length, camera sensor dimensions, target distance, required image coverage, and installation geometry should be considered together. TOWIN’s FOV Calculator can help evaluate the expected viewing area, while the Focal Length Calculator can assist with focal-length selection.

IR-Corrected Optical Performance

Unlike a lens that simply uses an IR cut filter, an IR-corrected lens is designed to maintain more consistent optical focus when the imaging system operates across different wavelength ranges. This is particularly important for surveillance cameras that use near-infrared illumination at night.

For day/night security systems, IR correction can help reduce focus shift when the camera changes between visible-light and near-infrared operating conditions. This makes the lens suitable for applications where maintaining image sharpness throughout changing illumination conditions is important.

For additional lens-selection information, TOWIN’s Lens Selection Guide provides guidance on matching lens characteristics with camera and application requirements.

Distortion Considerations

The specified distortion range is -59% to -3%. The wide-angle 2.8mm position has substantially greater distortion than the longer focal-length positions. This is an important consideration for applications involving geometric measurement, machine vision, or applications where straight-line preservation is critical.

For conventional surveillance, the wide field of view can be more important than geometric accuracy. However, if the camera is being used for measurement or precise spatial analysis, the actual distortion at the selected focal length should be evaluated. TOWIN’s Distortion Guide provides additional information on lens distortion and its impact on imaging.

Frequently Asked Questions

Q: What type of lens is this?
A: It is a 2MP motorized zoom CCTV lens with a 2.8–12mm focal-length range, Φ14 mount, P-Iris, step-motor zoom and focus, and IR-corrected optical performance.

Q: What sensor size is this lens designed for?
A: The specified image format is 1/2.7 inch.

Q: What is the horizontal field of view?
A: The horizontal FOV ranges from 114° at 2.8mm to 31° at 12mm.

Q: What is the advantage of the P-Iris?
A: P-Iris provides controlled aperture adjustment, helping the camera manage exposure and optical performance more precisely than a simple fixed aperture.

Q: Are the zoom and focus motorized?
A: Yes. Both zoom and focus use step motors, allowing electronic control of focal length and focus position.

Q: Is this lens IR corrected?
A: Yes. The specification explicitly identifies the lens as IR corrected, making it suitable for camera systems that operate with visible and near-infrared wavelengths.

Q: Is this a low-distortion lens?
A: No. The specified distortion range is -59% to -3%, so it should not be positioned as a dedicated low-distortion lens. The wide-angle end has substantially higher distortion.

Q: What is the minimum object distance?
A: The specified minimum object distance is 0.3 meter.

Technical Integration Support

When integrating this motorized zoom lens into a camera system, designers should verify the 1/2.7-inch image format, Φ14 mount, 13.45mm F.B.F.L., 2.8–12mm focal-length range, P-Iris control, motor-control requirements, and IR-correction requirements. These parameters directly affect mechanical compatibility, optical coverage, focusing behavior, and day/night imaging performance.
