CCTV Lens – D14055012716A3

D14055012716A3 is 1/2.7″ 5-50mm CCTV lens, High-resolution 4-Megapixel Low-distortion lens, F1.6 Low F-number Φ14 Mount lens, DC Auto IRIS.

5–50mm 4MP Φ14 Motorized Zoom CCTV Lens

This 5–50mm motorized zoom CCTV lens is designed for 1/2.7-inch sensors and supports up to 4MP resolution. With DC auto iris, step-motor-driven zoom and focus, and a Φ14 mount, it provides flexible remote framing for professional surveillance and intelligent security imaging systems.

Motorized Zoom CCTV Lens Core Highlights at a Glance

• 5–50mm motorized zoom range: Covers a broad focal-length range for flexible scene framing and target observation.
• 4MP imaging: Designed for 1/2.7-inch camera systems requiring detailed surveillance images.
• Step-motor zoom and focus: Enables electronically controlled adjustment for applications requiring remote lens operation.
• F1.6 aperture: Provides a relatively bright optical configuration for surveillance scenes with changing illumination.
• Φ14 mount: Suitable for camera platforms and optical assemblies designed around a special Φ14 interface.

Motorized Zoom CCTV Lens Applications

The 5–50mm focal-length range provides a practical combination of moderate field coverage and long-range viewing. At 5mm, the lens provides a 50.9° horizontal field of view, while the field narrows to 7.6° at 50mm. This allows the same camera system to switch between wider scene observation and tighter target framing without changing the lens.

The DC auto iris helps regulate the amount of light entering the optical system as scene brightness changes. The motorized zoom and focus are driven by step motors, making this lens suitable for camera systems where lens adjustment needs to be controlled electronically rather than manually.

The lens supports 4MP resolution on a 1/2.7-inch sensor and uses a Φ14 mount with a 9.53mm F.B.F.L. This makes mechanical interface compatibility an important consideration when integrating the lens with a camera module or customized optical housing. For other interface options, see the full range of Other Mount Lenses.

Core Application Scenes

• Long-range security monitoring: The 50mm telephoto end provides a narrow 7.6° horizontal FOV for more concentrated observation.
• Perimeter surveillance: Motorized focal-length adjustment allows operators to change the monitoring area according to scene requirements.
• Commercial and industrial security: The 5–50mm range can cover both general-area monitoring and closer target observation.
• Intelligent surveillance cameras: Step-motor zoom and focus support electronically controlled camera systems.
• Remote monitoring systems: Suitable for applications where manual lens adjustment is inconvenient or impractical.

Designed for motorized surveillance and intelligent security camera applications where variable focal length, remote adjustment, and 4MP imaging are required.

Compatible Device List

• Customized camera systems using a Φ14 optical interface

For help selecting the appropriate focal length and field of view for a camera system, the Lens Selection Guide provides useful reference information. You can also use the FOV Calculator to evaluate the relationship between sensor size, focal length, and viewing coverage.

Optical Performance and Zoom Range

The 5–50mm zoom range provides a 10× focal-length ratio. The shorter focal-length setting provides a wider 50.9° horizontal FOV for general scene coverage, while the 50mm setting reduces the horizontal FOV to 7.6° for more concentrated viewing.

The specified distortion range is -10% to 2%. Because distortion changes across the zoom range, system designers should evaluate the actual focal-length position and image-processing requirements when geometric accuracy is important. More information is available in TOWIN’s Distortion Guide.

Frequently Asked Questions

Q: What type of lens is this?
A: It is a 4MP motorized zoom CCTV lens with a Φ14 mount, 5–50mm focal-length range, DC auto iris, and step-motor-driven zoom and focus.

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

Q: What is the zoom range of this lens?
A: The focal length can be adjusted 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 the 5mm wide end to 7.6° at the 50mm telephoto end.

Q: Is the zoom manually operated?
A: No. The zoom is driven by a step motor, making it suitable for electronically controlled or remotely operated camera systems.

Q: Does the lens have auto iris?
A: Yes. It uses a DC auto iris system to regulate light entering the lens according to scene illumination.

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

Q: Is this lens a low-distortion lens?
A: The specified distortion is -10% to 2% across the lens range. It should therefore not automatically be classified as a dedicated low-distortion lens; the actual distortion requirement should be evaluated according to the specific focal-length position and application.

Technical Integration Support

When integrating this motorized zoom lens into a new camera platform, designers should verify the Φ14 mount, 9.53mm F.B.F.L., 1/2.7-inch image format, focal-length range, and motor-control requirements. These parameters affect mechanical compatibility, sensor coverage, focusing performance, and electronic control integration.
