The DF4820HD-DN is a 3-megapixel HD network camera built into a compact and lightweight box housing. It provides real-time Full HD video (1080p/30) using the H.264 codec and features automatic Day/Night operation supported by integrated ambient light sensing and a removable IR cut filter (ICR).
In addition, the DF4820HD-DN is equipped with a fast (large maximum aperture) and motor-driven P-Iris megapixel varifocal lens which allows for the convenient adjustment/configuration of the focal length (zoom), focus and iris (aperture) via the web browser. The novel P-Iris control technology, designed for a precise and automatic adjustment of the best iris position, thereby realises a significantly improved image quality with excellent contrast, brilliant clarity and enhanced detail resolution combined with a greater depth of field, compared to conventional DC auto iris lenses.
