Infrared reflections can degrade image quality in dome cameras by causing foggy, blurry, or mirrored effects when IR light reflects back into the lens. This paper identifies common causes such as nearby reflective surfaces, dirt, water droplets, dust, spider webs, external light sources, and excessive lens tilt that allows IR leakage. It outlines practical solutions, including proper camera placement, minimizing exposure to weather, regular cleaning, avoiding reflective surfaces, and reducing lens tilt. Technologies like Axis OptimizedIR adjust illumination intensity and beam width to reduce reflections, while semi-smoked domes further minimize glare, helping maintain clear nighttime video performance.
