CCTV Lens – CCL1230922AMPD

CCL1230922AMPD is 5-Megapixel resolution CCTV lens, 1/2.3″ 9-22mm manual zoom and focus lens, F1.4 aperture φ14 mount lens, DC Auto iris, IR corrected.

1/2.3″ 5MP 9–22mm IR Corrected φ14 Manual Zoom CCTV Lens

This 1/2.3″ 5MP 9–22mm manual zoom lens is designed for CCTV and security imaging systems requiring flexible focal-length adjustment, a fast F1.4 aperture, and IR-corrected optical performance. Its φ14 mount, DC auto iris, manual focus, and 1m minimum object distance make it suitable for compact camera systems where adjustable framing and stable imaging across visible and near-infrared wavelengths are required.

IR Corrected CCTV Lens Highlights at a Glance

• 9–22mm manual zoom range for flexible scene framing and viewing-distance adjustment
• 5MP optical resolution for detailed security and surveillance imaging
• F1.4 aperture provides strong light-gathering capability for demanding lighting conditions
• IR corrected optical design helps maintain focus consistency when imaging across visible and near-infrared wavelengths
• DC auto iris with φ14 mount supports compact camera integration and automatic exposure control

IR Corrected CCTV Lens Applications

Core Application Scenes

The 9–22mm focal-length range provides a practical balance between wider-area coverage and narrower scene framing. At 9mm, the lens provides a 42° horizontal FOV, while the field of view narrows to 19° at 22mm, allowing installers to adjust image composition according to the required monitoring distance and scene size.

With its F1.4 aperture and DC auto iris, this lens is suitable for CCTV systems that experience changing illumination levels. The manual zoom and manual focus configuration also allows the installer to establish the required viewing angle and focus position during camera setup.

The IR-corrected optical design makes the lens suitable for surveillance systems using near-infrared illumination, helping reduce wavelength-related focus changes between visible-light and IR-assisted imaging.

Compatible Devices

• 1/2.3″ security cameras
• 5MP CCTV camera modules
• Compact surveillance camera systems
• Day/night security cameras with IR illumination
• Camera modules requiring DC auto iris control
• Fixed-position surveillance systems requiring manual zoom adjustment
• Security imaging equipment using φ14 mounting interfaces

Designed for CCTV, security surveillance, day/night monitoring, and compact camera imaging applications where manual zoom flexibility and IR-corrected performance are required.

Frequently Asked Questions

Q1: What type of lens is the 9–22mm model?
A: It is a manual zoom lens with a focal-length range of 9–22mm. The focal length can be adjusted manually to change the horizontal field of view from 42° to 19°.

Q2: Is this lens a fixed focal lens?
A: No. The 9–22mm focal-length range means it is a variable focal-length zoom lens rather than a fixed focal lens.

Q3: What camera sensor size is this lens designed for?
A: The lens is specified for a 1/2.3″ image format and supports up to 5 Megapixel resolution.

Q4: What is the advantage of the F1.4 aperture?
A: The F1.4 aperture provides a relatively large optical opening, allowing more light to reach the sensor. This is useful for CCTV systems operating under changing or limited lighting conditions.

Q5: What does IR Corrected mean?
A: IR correction is an optical design feature intended to reduce focus differences between visible and near-infrared wavelengths, which is particularly useful in day/night surveillance systems using IR illumination.

Q6: Does the lens have automatic zoom and focus?
A: No. Both zoom and focus are specified as manual. The iris uses DC auto iris control.

Q7: What is the minimum object distance of this lens?
A: The specified M.O.D. is 1 meter, meaning the lens is designed with a minimum object distance of 1m under the specified optical configuration.
