The DF4820HD-DN/IR is a weather-proof 2-megapixel HD network camera with automatic day/night switching and integrated infrared illumination. The camera provides real-time full HD video (1080p/30) using the H.264 codec.

Besides a comprehensive set of automatic and manual image optimisation functions and many other setting options, it features automatic day/night operation supported by integrated ambient light sensing, a removable IR cut filter (ICR) and an integrated homogeneous IR illumination provided by semi-covert 850 nm high power LEDs in order to meet even the most demanding of surveillance conditions.

In addition, the camera is equipped with a motor-driven P-Iris megapixel varifocal lens. Focal length (zoom), focus and iris (aperture) can be configured conveniently with a web browser. The P-Iris control technology thereby has been designed to realise a significantly improved image quality compared to conventional DC auto iris lenses 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 achieved.

Built into an IP66-rated weather-proof enclosure, the camera is designed for both indoor and outdoor applications. The camera is operated via power over Ethernet which allows for an easy, quick and cost-effective cabling and commissioning.
