How to install Hanwha Techwin SLA-M2890PN

• Power down your surveillance system and confirm camera compatibility with CS-mount lenses.
• Remove the existing lens from your CS-mount camera body, taking care not to damage the mount or sensor.
• Align the SLA-M2890PN with the camera’s CS-mount interface. Gently engage the lens and rotate until it seats securely, ensuring there are no gaps or misalignment.
• Lightly tighten the mounting ring or screws to fix the lens firmly in place. Avoid over-tightening, which can damage the thread or lens housing.
• Power on the system and perform a quick foreground calibration. Use the camera’s zoom and focus controls to frame the desired scene; adjust the zoom from wide-angle to telephoto as needed for optimal coverage.
• Fine-tune focus at each focal setting to maintain sharpness across the zoom range. If your camera supports auto-iris or electronic controls, configure them per your installation requirements for automatic exposure adjustments.
• Verify image quality under varying lighting conditions (daylight, backlit scenes, and low light). Make any necessary exposure or white balance adjustments in the camera settings to maximize clarity and color accuracy.
• Document the installation details (lens model, focal setting, and any camera presets) for future maintenance or adjustments.
