Key Features

• 3.5-8mm varifocal range supports flexible field-of-view adjustment during installation.
• DC auto iris automatically adapts exposure to changing light conditions.
• F1.4 aperture helps improve image brightness in lower-light scenes.
• Adjustable lens design reduces the need to stock multiple fixed focal length lenses.

Technical Context

The varifocal design lets installers adjust the viewing angle after the camera position is selected, helping avoid mismatches that can occur with fixed monofocal lenses. This makes the lens useful for projects where exact coverage requirements are determined on site.

Installation Notes

Install on a compatible camera and adjust the focal length with the lens dial to match the required scene coverage. After framing the view, set focus carefully and verify exposure behavior under the expected day and night lighting conditions.
