Note: Gasket Back Cover - Some products have a paper backing on the gasket. Please remove it before installation. Mounting - It is recommended that the camera be mounted to a flat non-porous surface for best results. The mounting holes and the area around the mounting screws should be sealed with silicone to prevent water or moisture from entering into the unit.
4. ADJUSTMENTS For optimum picture quality the camera lens must be as close as possible to the dome’s inside face, without touching. However, the foam ring around the lens should be adjusted to seal against the dome, minimizing any side light interference, but without obstructing the field of view.
