Frequently asked questions
How does the varifocal design simplify deployment?
The 2.8-11mm focal range allows system integrators to easily adjust the angle of view directly on site. This flexibility eliminates the need to carry multiple fixed lenses, ensuring a highly efficient installation process while perfectly matching the camera's field of view to the specific environment.
Is this lens suitable for low-light or nighttime monitoring?
Yes. The lens is IR-corrected to ensure sharp, focused images across a wide range of lighting conditions. When paired with infrared illuminators, it maintains reliable visibility during the day and in darkness, providing continuous context without losing focus.
What are the operational benefits of the DC-iris control?
The DC-iris functionality automatically adjusts the lens opening in response to changing light levels, ensuring optimal image exposure at all times. Using a standard four-pin connector, it integrates seamlessly with the camera to deliver consistent visual clarity, even in environments with highly dynamic lighting.
How durable is the mechanical construction of the lens?
Built for reliable, long-term performance, the lens features a robust construction designed to withstand the environmental stress of demanding security installations. It easily handles frequent auto-iris operations, ensuring uninterrupted visibility and dependable performance where it matters most.
