The DDF4820HDV-DN is a HD network camera built into a vandal-resistant (IK10) dome enclosure. It provides real-time Full HD video (1080p/30) using the H.264 codec, currently, the most advanced standard for high-efficiency video compression, and supports resolutions up to 3-megapixel.
Besides a comprehensive set of automatic and manual image optimization functions and many other setting options, it features automatic Day/Night operation supported by integrated ambient light sensing and a removable IR cut filter (ICR).
In addition, the camera is equipped with a fast (large maximum aperture) and motor-driven P-Iris megapixel varifocal lens (F1.2 – F2.3 / 3 – 9 mm) which allows for the convenient adjustment/configuration of the zoom, focus and iris via the web browser. The novel P-Iris control technology, designed for a precise and automatic adjustment of the optimum aperture, thereby realizes a significantly improved image quality compared to conventional DC auto iris lenses under almost all lighting conditions.
