To prevent reflections from built-in IR illuminators from degrading the image quality, an installer can adjust the camera's field of view. By repositioning the camera or slightly altering its angle, the installer can minimize the direct reflection of IR light back into the lens, which often causes glare and reduces image clarity. Axis installation guidelines recommend adjusting the camera’s position to avoid reflective surfaces and ensure optimal use of IR illumination for clear, unobstructed images.

Focusing a camera with an auto iris is more accurate when set during lowlight conditions. In low light, the iris opens wider, resulting in a shorter depth of field. This forces the focus to be more precise within that narrower range, ensuring that the focus is set correctly. When lighting conditions improve and the iris closes down, the depth of field increases, maintaining a broader range of focus.
