Product Description
The 2.8-12mm varifocal lens is designed for security cameras, surveillance systems and compact imaging applications requiring flexible field-of-view adjustment. Supporting 1/2.7″ image formats and 3MP resolution, the lens provides a wide horizontal field of view from 122° to 28°, allowing users to adjust scene coverage according to different monitoring requirements.
With a F1.3-C aperture range, the lens provides flexible light control across different focal lengths and lighting environments. The auto iris helps maintain suitable exposure, while manual focus and zoom adjustments allow users to precisely configure the imaging range and viewing angle.
The lens features IR correction to help maintain image consistency when used with infrared illumination. With a 0.1m minimum object distance and Φ14 mounting interface, it provides a flexible optical solution for security cameras, surveillance equipment and compact monitoring systems.
Key Features
2.8-12mm Varifocal Range
The 2.8-12mm focal length range allows users to adjust the viewing angle according to different surveillance and monitoring requirements, providing greater flexibility than fixed focal length lenses.
