DESCRIPTION
The Dallmeier DDF4820HDV-DN is a 3-megapixel HD network camera built into a vandal-resistant (IK10) dome enclosure.
The camera 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 (ICR1)).
In addition, the camera 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 (optimum aperture), thereby realizes a significantly improved image quality2) with excellent contrast, brilliant clarity and enhanced detail resolution combined with a greater depth of field, under almost all lighting conditions.
In conjunction with the Digital Image Shift function, which provides for a subsequent digital fine alignment of the image section, a convenient and straightforward installation process of the camera is guaranteed.
Depending on the requirements, the camera can be conventionally supplied with 12V DC or conveniently operated via Power over Ethernet (PoE Class 0, IEEE 802.3af) which allows for an easy, quick and cost-effective cabling and commissioning.
