How to install AXIS 2.80-8.0mm f/1.2 Varifocal CS-Mount Lens

• Preparation: Confirm that your camera supports CS-mount lenses and is powered off before installation to prevent any electrical or mechanical issues during replacement.
• Remove existing lens (if applicable): If you are upgrading an existing CS-mount lens, carefully loosen the retaining screws and detach the current lens from the camera body, taking note of any spacers or shims in place.
• Align and install: Align the new AXIS varifocal lens with the CS-mount socket, ensuring the lens is seated evenly. Gently twist and secure the lens into place using the appropriate screws or mounting hardware provided with your camera system.
• Connect and secure: Reattach any connectors or mounts, and ensure the lens is firmly secured to prevent creeping or misalignment during operation.
• Initial focus and zoom adjustments: Power on the camera and use the camera’s built-in focus and zoom controls (or the lens’s manual adjustment) to achieve a sharp image. Start with a mid-zoom setting, then adjust the focal length to suit the scene—for example, wide-angle for broad surveillance coverage, or longer focal lengths for detailed views of entry points.
• Fine-tuning and verification: Verify that the field of view, edge sharpness, and brightness meet your monitoring requirements. Perform a quick test under typical lighting conditions and adjust the zoom and focus as needed. If your system supports Auto Iris or electronic zoom controls, set these features according to your camera’s capabilities and security objectives.
