Key Features

• 2.9-8.2mm varifocal range supports flexible wide-to-medium surveillance framing.
• F1.0 aperture maximizes light transmission for low-light monitoring.
• DC auto iris automatically adjusts exposure in areas with significant lighting variation.
• CS-mount design supports straightforward installation on compatible cameras.
• All-glass optics with metal barrel and mount provide durable general-purpose security use.

Technical Context

When used with a 1/3" camera, the lens provides a horizontal angle of view from 98.3° to 35.2°, a vertical angle of view from 70.7° to 26.3°, and a diagonal angle of view from 133.9° to 44.2°. This range makes it suitable for both broad coverage and more focused monitoring.

Installation Notes

Use with compatible 1/3" CS-mount cameras that support DC auto iris operation. After mounting, adjust focal length and focus for the required coverage area, then confirm exposure response under the expected lighting conditions.
