4. Operating Instructions

4.1 Adjusting the Varifocal Lens

The AHCAM631A features a varifocal lens, allowing you to adjust the field of view and focus. This adjustment is typically done manually after installation.

1. Access Lens: Carefully open the dome cover to access the lens adjustment screws.
2. Adjust Zoom: Rotate the zoom adjustment ring to achieve the desired field of view (between 2.8mm wide angle and 12mm telephoto).
3. Adjust Focus: Rotate the focus adjustment ring until the image on your monitor is clear and sharp.
4. Secure Cover: Once adjustments are complete, securely close the dome cover to maintain its IP66 rating.

4.2 On-Screen Display (OSD) Menu

Many AHD cameras feature an OSD menu for advanced settings adjustments (e.g., exposure, white balance, DNR). Access to the OSD menu is typically controlled via a joystick on the camera cable or through a UTC (Up The Coax) controller connected to your DVR.

• Refer to your DVR's manual or the camera's specific OSD instructions for detailed navigation and setting adjustments.
• Common settings include: Brightness, Contrast, Sharpness, Backlight Compensation (BLC), Wide Dynamic Range (WDR), Digital Noise Reduction (DNR), and Day/Night mode.

5. Maintenance

5.1 Cleaning the Camera

Regular cleaning helps maintain optimal image quality.

• Use a soft, clean cloth to wipe the dome cover.
• For stubborn dirt, dampen the cloth slightly with water or a mild, non-abrasive cleaning solution.
• Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the dome's surface.

5.2 Environmental Considerations

While the camera has an IP66 rating, extreme environmental conditions can affect its lifespan and performance.

• Ensure proper ventilation if installed in an enclosed space.
• Avoid direct exposure to lightning or extreme voltage fluctuations.
• Periodically check cable connections for corrosion or damage, especially in outdoor installations.
