    Abstract: A domed surveillance camera capable of blocking scattered reflection and stray light. The domed surveillance camera may include an infrared camera module configured to include a lens, infrared lighting components disposed around the infrared camera module, and a domed cover configured to surround the infrared camera module and the infrared lighting components. Infrared shielding structure configured to block infrared rays from the infrared lighting components from being reflected by the domed cover and being incident on a lens is formed to cross the thickness of the domed cover within the domed cover. The surveillance camera can prevent the distortion of a captured image by blocking stray light incident on the lens due to scattered reflection.
