D14321012716A2 is 3.2-10mm Wide-angle CCTV lens, 1/2.7″ manual zoom and focus lens, F1.6~F2.9 aperture M14 mount lens, 2 Megapixel, DC Auto IRIS.

3.2-10mm M14 2MP Manual Zoom Wide Angle CCTV Lens

This 3.2-10mm M14 manual zoom CCTV lens is designed for surveillance systems that require flexible field-of-view adjustment across different monitoring distances. With a 137° maximum diagonal FOV, 2MP resolution, F1.6–F2.9 aperture, and DC auto iris, it provides adaptable imaging performance for wide-area security cameras and compact monitoring systems.

M14 Manual Zoom CCTV Lens Core Highlights

• 3.2–10mm manual zoom range for adjustable surveillance framing
• 137° maximum diagonal FOV for broad-area monitoring at the wide end
• 2MP optical resolution for standard security and surveillance cameras
• F1.6–F2.9 aperture range with DC auto iris for changing lighting conditions
• M14 mount for compatible compact CCTV camera designs

M14 Manual Zoom CCTV Lens Applications

Core Application Scenes

The 3.2–10mm focal-length range gives installers flexibility to adjust the image framing after the camera has been positioned. At 3.2mm, the lens provides a 137° diagonal field of view, making it suitable for broad-area monitoring. At 10mm, the viewing angle becomes significantly narrower, allowing the camera to concentrate on a more specific area.

Designed for flexible CCTV surveillance applications, the lens can be used for:

• Indoor security monitoring
• Retail stores and commercial spaces
• Building entrances
• Reception and waiting areas
• Corridors and passageways
• Office surveillance
• Small-area facility monitoring
• General-purpose IP/CCTV camera systems
• Close-range security observation

The 0.2m M.O.D. also allows the lens to be positioned for relatively close monitoring scenes where a short working distance is required.

Compatible Device List

This lens can be integrated into compatible:

• CCTV cameras
• Security camera modules
• Compact IP camera systems
• Indoor surveillance cameras
• Commercial monitoring cameras
• Embedded security camera assemblies
• OEM camera systems

The M14 mount should be matched with the mechanical interface and housing design of the target camera before integration.

Optical Design & Selection Considerations

The main advantage of this lens is its manual 3.2–10mm zoom range. The wide end provides broad scene coverage, while the longer focal-length setting allows the camera to obtain a narrower view without changing the lens.

The specified FOV ranges from 137° to 39° diagonal, 114° to 33° horizontal, and 60° to 19° vertical. This makes the lens suitable for surveillance systems where the required viewing area can vary between installations.

The DC auto iris is another important feature for security applications. It allows the camera system to control the iris according to the available light, making the lens suitable for scenes with changing illumination.

Before selecting the lens, users should consider sensor format, working distance, required FOV, resolution, mounting interface, and back focal requirements. TOWIN’s Lens Selection Guide provides additional information about selecting the appropriate optical configuration.

Frequently Asked Questions

Q1: What type of lens is this 3.2–10mm M14 lens?
A: It is a manual zoom wide-angle CCTV lens designed for 1/2.7″ camera sensors, with a 3.2–10mm adjustable focal-length range.

Q2: What is the maximum field of view?
A: The maximum specified FOV is 137° diagonal, 114° horizontal, and 60° vertical, achieved at the 3.2mm wide-angle setting.

Q3: Can the focal length be adjusted during installation?
A: Yes. The lens uses a manual 3.2–10mm zoom mechanism, allowing the installer to adjust the viewing angle according to the surveillance scene.

Q4: What does the DC auto iris do?
A: The DC auto iris allows the camera system to control the lens aperture according to changing illumination, helping maintain a suitable exposure across different lighting conditions.

Q5: What sensor format is this lens designed for?
A: The lens is specified for a 1/2.7″ image format and should be paired with a compatible sensor and camera module.

Q6: Is this lens suitable for indoor CCTV applications?
A: Yes. Its wide-angle capability, manual zoom range, and DC auto iris make it suitable for indoor surveillance environments such as retail stores, offices, entrances, and corridors.

Q7: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, providing flexibility for relatively close-range monitoring applications.

Q8: What should I check before integrating this lens into a camera?
A: Check the sensor format, M14 mechanical interface, required focal-length range, FOV, working distance, and back focal requirements. The target camera should be compatible with the lens’s optical and mechanical specifications.
