AXIS - 9 mm to 40 mm f/1.5 Telephoto Varifocal Lens for CS Mount

Upgrade your security camera setup with a dedicated telephoto solution that combines long-range reach, superb image quality, and flexible exposure control. The AXIS 9-40 mm f/1.5 Telephoto Varifocal CS-mount Lens is engineered for megapixel cameras, delivering a crisp, high-resolution image across its impressive 9-40 mm focal length and a fast f/1.5 aperture. This compact lens is optimized for surveillance applications where distant subjects matter—think entrances, parking lots, building perimeters, and critical facilities—without sacrificing overall scene context. Its design emphasizes day-and-night performance, with IR correction that helps preserve sharpness as lighting conditions change and with iris options that adapt to your camera workflow for consistent exposure at varying distances. Whether you need broad situational awareness at the wide end or tight facial identification at the telephoto end, this varifocal lens provides reliable optics and precise control in a compact package.

• 16x telephoto magnification across a 9-40 mm focal length range, enabling both wide-area surveillance and close-up detail capture on megapixel cameras for better identification and evidence collection.
• Large f/1.5 aperture for improved low-light sensitivity and subject isolation, helping you maintain image quality as lighting conditions fade or glare increases.
• Supports both P-Iris and DC Iris, giving precise exposure control to match camera workflows and ensure optimal depth of field and consistent image brightness across the zoom range.
• IR-corrected optics designed to minimize blur and ghosting in night or low-light scenes, delivering clearer results when infrared illumination is used or when ambient light is limited.
• Compact, robust CS-mount design tailored for megapixel surveillance systems, easy integration with compatible cameras, and flexibility for a variety of installation scenarios from ceiling mounts to wall brackets.

how to install AXIS 9-40 mm f/1.5 Telephoto Varifocal CS-Mount Lens

Follow these general steps to install the AXIS telephoto varifocal lens on a CS-mount megapixel camera. Always power down your equipment before performing hardware changes and handle optics with care to avoid damage.

• Power down the camera system and disconnect power before beginning the installation.
• Remove any existing lens from the CS-mount camera, and inspect the mount surface for dust or debris. Clean if necessary to ensure a proper seal and smooth operation.
• Align the lens with the camera’s CS-mount, ensuring the alignment notch or index marks line up correctly. Gently thread the lens onto the mount until it is snug, then secure using the mounting screws supplied with your camera or lens kit.
• Set the lens to a mid-range focal length (for example, around 20-25 mm) and perform a basic focus adjustment. Power the system back up and use the camera’s zoom and focus controls to refine image sharpness at the selected distance.
• Configure iris control in the camera or lens as appropriate. If using P-Iris, enable P-Iris control in the camera settings and adjust to achieve the desired depth of field and exposure. If using DC Iris, select DC Iris mode and tune exposure via the camera’s iris control features. Validate exposure under typical lighting conditions and fine-tune focus and zoom to optimize target detail across the frame.

Frequently asked questions
