A P-iris lens has better iris control in all lighting conditions. P-iris (Precise iris) lenses are designed to optimize the depth of field, contrast, and resolution of the camera by precisely controlling the iris opening, ensuring optimal image quality in varying light conditions. This technology is superior to manual, fixed, and DC-iris lenses. Axis Communications' product specifications highlight the benefits of P-iris lenses in maintaining image quality across different lighting scenarios.
