CCTV Lens – D17339512712A5ICR

D17339512712A5ICR is 3.3-9.5mm CCTV lens with removable IR cut filter, wide field of view (110°~35°), 1/2.7″ 5-megapixel resolution Low distortion lens, DC auto iris.

5MP 3.3-9.5mm Φ16.8 Motorized Zoom CCTV Lens

This 5MP 3.3-9.5mm motorized zoom CCTV lens combines a wide 110° horizontal field of view, DC auto iris, step-motor focus and zoom, and a removable IR cut filter. With a compact Φ16.8 ±0.02mm mounting interface, it is designed for compact CCTV camera modules, wide-area security imaging, and day/night surveillance systems requiring flexible focal-length adjustment.

Φ16.8 Motorized Zoom CCTV Lens Core Highlights

• 3.3–9.5mm motorized zoom range provides flexible coverage from wide-area scenes to narrower viewing requirements.
• 110°–35° horizontal FOV supports wide-area CCTV monitoring while allowing optical zoom adjustment.
• 5MP resolution provides detailed imaging for professional surveillance camera systems.
• F1.3–2.3 variable aperture with DC auto iris helps adapt exposure to changing scene illumination.
• Step-motor focus and zoom with removable IR cut filter supports motorized camera operation and day/night switching configurations.

Φ16.8 Motorized Zoom CCTV Lens Applications

Core Application Scenes

Wide-Area Security Monitoring

The 3.3mm wide end provides a 110° horizontal field of view, making this lens suitable for monitoring entrances, reception areas, corridors, retail spaces, and other scenes where a broad viewing area is required. The motorized zoom allows installers or system integrators to adjust the viewing range without replacing the lens.

Motorized CCTV Camera Modules

The combination of step-motor zoom, step-motor focus, and DC auto iris makes this lens suitable for motorized CCTV camera assemblies. The 3.3–9.5mm focal range allows one optical platform to support different surveillance distances and framing requirements.

Day/Night Surveillance

The removable IR cut filter provides a practical configuration option for camera systems that switch between visible-light and near-infrared operating modes. It can be integrated into surveillance designs requiring different optical filtering configurations between daytime and nighttime operation.

Retail and Commercial Security

For retail stores, entrances, offices, and commercial facilities, the wide-angle 3.3mm setting can cover larger areas, while the 9.5mm telephoto setting can provide a tighter view of selected areas. This makes the lens suitable for flexible security camera deployment.

Compact Embedded Imaging Systems

The Φ16.8 ±0.02mm mount and 5.9 ±0.1mm F.B.F.L. are suitable for compact camera assemblies where the optical interface and mechanical dimensions need to be controlled during system integration.

Designed for motorized CCTV surveillance applications, this lens provides adjustable framing, automatic exposure control, and removable IR filtering in a compact optical package.

For applications requiring a different focal-length range or mounting interface, users can review the complete CCTV Lens range or contact TOWIN for optical customization.

Lens Selection Considerations

The 110° wide-angle field of view makes this lens suitable when broad scene coverage is more important than geometric correction. Its TV distortion is specified as < -11%, so it should not be treated as a low-distortion measurement lens.

For applications where distortion characteristics are important, refer to the Distortion Guide before selecting the optical configuration.

The 3.3–9.5mm focal range also makes the lens useful when the required viewing area may change after camera installation. For preliminary lens selection, the Lens Selection Guide can help evaluate focal length, sensor format, field of view, and application requirements.

Frequently Asked Questions

Q: What type of lens is this 3.3–9.5mm model?

A: This motorized wide-angle zoom lens is built mainly for CCTV and security imaging, integrating motorized zoom, motorized focus and DC auto iris.

Q: What is the horizontal field of view of this lens?

A: Horizontal FOV spans 110° at 3.3mm down to 35° at 9.5mm, enabling the camera to toggle between wide scene coverage and a tighter view.

Q: Does this lens have IR correction?

A: The lens comes with a removable IR cut filter as specified. This does not mean IR-corrected optics; IR correction refers to optical compensation across visible and near-infrared wavelengths.

Q: What camera sensor size is this lens designed for?

A: The lens is specified for a 1/2.7″ image format and provides up to 5MP imaging performance.

Q: What is the purpose of the step motor?

A: The step motor controls the zoom and focus functions, allowing the lens to be integrated into motorized camera systems where focal length and focus need to be adjusted electronically.

Q: Is this lens suitable for low-light CCTV applications?

A: It has a bright F1.3 wide-end aperture and DC auto iris for variable lighting. Actual low-light performance depends on the sensor, exposure settings, illumination and system design.

Q: Can TOWIN customize this type of lens?

A: TOWIN can evaluate optical and mechanical requirements such as focal-length range, field of view, sensor format, mount dimensions, focus/zoom drive, and IR filter configuration. For project-specific requirements, contact the TOWIN optical engineering team.
