Abstract
A monitoring camera having a compound window arranged in a frame of a camera housing, and a camera head arranged inside the housing, is disclosed. The compound window has an inner transparent plate, closest to the camera head, and an outer protective window, arranged in a plane parallel to the transparent plate, on an outside thereof, and the compound window further comprises a heating arrangement arranged and configured to supply thermal energy to peripheral areas of the transparent plate. The transparent plate has a greater heat conductivity than the protective window and is arranged in close proximity to the protective window, so thermal energy will be transferred from the heating arrangement to the transparent plate and then efficiently transferred to the protective window.
