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.
