CCTV Lens – CCL1270550AMPR

CCL1270550AMPR is a 5-50mm Auto Iris CS-mount CCTV lens.  And it is IR corrected for day and night CCTV surveillance.  It is for 1/3″, 1/2.7″, 3-4Megapixel sensors.  And the large aperture F1.4 is suitable for low light security.

Product Description

The 5-50mm CS-Mount CCTV lens is designed for camera systems requiring flexible focal length adjustment, high image quality and reliable performance across different viewing distances. Supporting 1/2.7″ image formats and 3MP resolution, the lens provides a horizontal field of view from 50.9° to 6.2°, allowing users to switch between wide-area observation and narrow-angle imaging.

With a constant F1.4 aperture, the lens provides strong light-gathering capability across its focal length range, supporting reliable imaging in challenging lighting conditions. The DC Auto iris provides automatic exposure control, while manual focus and zoom adjustment allow users to configure the lens according to specific installation and monitoring requirements.

Featuring IR correction, a CS mount and an adjustable 5-50mm focal length, this lens is suitable for security cameras, industrial monitoring, traffic surveillance and other imaging applications requiring flexible field-of-view control.

Key Features

5-50mm Varifocal Range

The 5-50mm focal length range allows users to adjust the field of view from wide-angle observation to narrow-angle imaging without replacing the lens.

3MP Resolution

Supporting 3MP resolution, the lens provides clear and detailed imaging for security, monitoring and industrial camera systems.

Wide-to-Narrow Field of View

The horizontal FOV ranges from 50.9° to 6.2°, providing flexibility for both broad-area surveillance and long-range subject observation.

F1.4 Large Aperture

The F1.4 aperture provides strong light-gathering capability, helping maintain image quality in low-light and variable lighting environments.

DC Auto Iris

The DC Auto iris automatically adjusts the amount of light entering the lens, helping maintain appropriate image exposure under changing lighting conditions.

IR Corrected Optical Design

The IR-corrected design helps maintain consistent focus between visible and near-infrared wavelengths, making the lens suitable for cameras using IR illumination.

CS-Mount Compatibility

The CS mount provides broad compatibility with standard surveillance and industrial camera platforms.

CCTV Lens Applications

Security Surveillance

The 5-50mm varifocal range allows security cameras to cover wide areas while also providing narrower viewing angles for more detailed monitoring.

Industrial Monitoring

This lens is suitable for industrial monitoring systems requiring flexible field-of-view adjustment and reliable imaging performance.

Traffic Surveillance

The adjustable focal length makes the lens suitable for traffic monitoring applications where camera viewing requirements can vary according to installation distance.

Long-Range Observation

The 50mm maximum focal length enables narrower fields of view for observing subjects at relatively longer distances.

Low-Light Security Cameras

The F1.4 aperture provides strong light-gathering capability, supporting surveillance systems operating under challenging lighting conditions.
