CCTV Lens – D14055012720A2ICR

D14055012720A2ICR is 1/2.7″ 5-50mm CCTV lens with removable IR cut filter, F2.0 aperture Φ14 Mount lens, DC Auto iris, 2 Megapixel resolution.

5–50mm 2MP Φ14 Motorized Zoom CCTV Lens with Removable IR Cut Filter

This 5–50mm motorized zoom CCTV lens is designed for 1/2.7-inch camera systems requiring flexible focal-length adjustment and electronically controlled focus and zoom. It combines 2MP imaging, F2.0 aperture, DC auto iris, step-motor zoom and focus, and a removable IR cut filter for day/night surveillance camera integration.

Motorized Zoom CCTV Lens Core Highlights at a Glance

• 5–50mm 10× zoom range: Provides flexible framing from a 50.9° horizontal FOV at the wide end to 7.6° at the telephoto end.
• 2MP optical performance: Designed for 1/2.7-inch surveillance camera systems requiring reliable standard-definition HD imaging.
• Motorized zoom and focus: Step motors enable electronic adjustment for remotely controlled camera platforms.
• DC auto iris: Automatically manages the amount of incoming light as scene illumination changes.
• Removable IR cut filter: Supports camera architectures that require a switchable optical path for day/night imaging configurations.

Motorized Zoom CCTV Lens Applications

The 5–50mm focal-length range gives this lens a broad working range for surveillance systems that need to move between general-area coverage and narrower target observation. At 5mm, the lens provides a 50.9° horizontal field of view, while the 50mm setting narrows the view to 7.6°, allowing operators or camera controllers to adjust scene framing electronically.

The lens uses step motors for both zoom and focus, making it suitable for camera systems where lens positioning needs to be controlled without physically accessing the lens. The DC auto iris provides automatic aperture control in response to changing illumination.

A key feature is the removable IR cut filter. This feature can be integrated into camera architectures that need to change the optical filtering configuration between different operating conditions. It should be distinguished from an IR-corrected lens: the presence of a removable IR cut filter does not by itself indicate that the optical design is corrected for infrared focus shift.

Core Application Scenes

• Day/night surveillance: The removable IR cut filter supports camera designs requiring different optical filtering configurations for changing lighting conditions.
• Perimeter monitoring: The 50mm telephoto position provides a narrow 7.6° horizontal FOV for concentrated observation.
• Commercial security: The 5–50mm range allows one camera platform to cover wider areas and selected targets.
• Remote-controlled CCTV: Step-motor zoom and focus are suitable for electronically controlled surveillance systems.
• Indoor and outdoor camera integration: The combination of motorized adjustment and DC auto iris supports changing scene conditions.

Designed for motorized CCTV and day/night surveillance applications where variable focal length, electronic zoom/focus control, and removable IR filtering are required.

Compatible Device List

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

Because this lens uses a special Φ14 interface rather than a standard C- or CS-mount configuration, mechanical compatibility should be checked during camera integration. TOWIN’s Other Mount Lenses category provides additional optical interface options for specialized camera designs.

5–50mm Motorized Zoom Performance

The 5–50mm focal-length range provides a 10× zoom ratio. The wide end is useful for establishing a larger monitoring area, while the telephoto end provides a narrower viewing angle for more concentrated observation.

When selecting a focal length for a particular installation, sensor dimensions, target distance, required coverage, and desired image detail should all be considered. TOWIN’s FOV Calculator can be used to evaluate field-of-view requirements, while the Focal Length Calculator can help determine a suitable focal length from the imaging geometry.

Removable IR Cut Filter for Day/Night Camera Systems

The removable IR cut filter is an important integration feature for surveillance cameras that need different spectral filtering configurations. In a typical day/night architecture, an IR cut filter can be positioned in or removed from the optical path according to the camera’s operating mode.

This feature should not be confused with IR correction. An IR-corrected lens refers to optical correction intended to maintain focus performance across visible and near-infrared wavelengths, while a removable IR cut filter primarily changes the spectral transmission characteristics of the camera system.

Distortion Considerations

The specified distortion range is -14% to 2%. Since distortion varies across the 5–50mm zoom range, system designers should evaluate the actual focal-length position when image geometry is important. Applications requiring precise geometric measurement may require additional optical or software correction.

For more information about how lens distortion affects imaging performance, refer to the Distortion Guide in TOWIN’s Knowledge Center.

Frequently Asked Questions

Q: What type of lens is this?
A: It is a 2MP motorized zoom CCTV lens with a 5–50mm focal-length range, Φ14 mount, DC auto iris, step-motor zoom and focus, and a removable IR cut filter.

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

Q: What is the zoom ratio?
A: The focal length ranges from 5mm to 50mm, providing a 10× focal-length range.

Q: What is the horizontal field of view?
A: The horizontal FOV ranges from 50.9° at 5mm to 7.6° at 50mm.

Q: Are the zoom and focus manually adjusted?
A: No. Both zoom and focus use step motors for electronic adjustment.

A: It allows the camera system to change its optical filtering configuration, which is useful for day/night surveillance architectures.

Q: Is this lens IR corrected?
A: The specification only states that it has a removable IR cut filter. This does not indicate that the lens itself is optically IR corrected.

Q: What is the minimum object distance?
A: The specified minimum object distance is 1 meter.

Technical Integration Support

When integrating this lens into a camera platform, designers should verify the 1/2.7-inch image format, Φ14 mount, 9.3mm F.B.F.L., 5–50mm focal-length range, motor-control interface, and removable IR cut filter configuration. These parameters affect optical coverage, mechanical fit, focusing behavior, and camera-system integration.
