Lens AXIS 5901-101 CS‑mount 2.8–8.5 mm for AXIS Q1615 Mk II / Q1615‑E Mk II, black

Axis 5901-101 is an intelligent varifocal i-CS lens with a focal length range of 2.8–8.5 mm and IR correction. It is designed for use with Axis cameras that support i-CS lenses and is finished in black. The lens uses a CS mount interface and provides adjustable field of view to suit different monitoring needs.

Advantages

The varifocal 2.8–8.5 mm range allows flexible framing from wide-angle to moderate telephoto without replacing the lens. IR correction ensures improved image quality under infrared illumination, maintaining focus and clarity in low-light or night conditions. The i-CS design enables easy integration and remote adjustment when paired with compatible Axis cameras, simplifying installation and configuration.

Suitable for

• Indoor and outdoor surveillance where variable framing is required
• Low-light or IR-illuminated environments
• Cameras that require CS mount lenses and support i-CS functionality (for example AXIS Q1615 Mk II and AXIS Q1615-E Mk II)

Key specifications

How to use

Mount the lens onto a compatible Axis camera with a CS mount and secure it according to the camera manufacturer’s instructions. Use the camera’s i-CS controls to adjust focal length and focus as needed for the scene. Verify IR focus and framing after installation, especially if the camera will operate under infrared illumination.

Usage recommendations

For optimal results, pair this lens with Axis camera models that list i-CS lens support and perform both daytime and IR calibration on-site to ensure sharp focus across the entire focal range.
