Description

Axis 5800-671 CS-Mount 2.8-8mm F1.2 P-Iris Varifocal Lens

The Axis 5800-671 is a premium CS-mount varifocal lens engineered for 5MP network cameras requiring flexible focal length coverage and superior low-light performance. With its 2.8-8mm range and F1.2 maximum aperture, this lens delivers exceptional image quality across diverse lighting conditions and surveillance scenarios.

Key Features

  • 2.8-8mm varifocal range for adaptable field-of-view coverage
  • F1.2 maximum aperture for superior low-light sensitivity
  • P-Iris (Precise Iris) technology for accurate exposure control
  • Optimized for 5MP resolution cameras
  • CS-mount compatibility with Axis network cameras
  • Motorized focus and iris control

Technical Highlights

The P-Iris mechanism provides precise aperture management, eliminating iris flicker and ensuring consistent image quality regardless of lighting variations. The wide F1.2 aperture maximizes light transmission, making this lens ideal for low-light environments such as parking facilities, building entries, and indoor spaces with limited illumination. The 2.8-8mm varifocal range (approximately 2.9x zoom) enables operators to adjust coverage from wide-angle monitoring to detailed target surveillance without changing lenses.

Applications

Ideal for retail environments, office buildings, educational facilities, and perimeter monitoring where flexible focal length and excellent low-light capability are essential. The precise iris control ensures reliable performance in mixed lighting conditions and high-contrast scenes.
