New cost-efficient IR camera: DF4820HD-DN/IR

Product Profile

With the DF4820HD-DN/IR, Dallmeier announces the market launch of an IR camera developed and manufactured in Germany, which combines high quality and affordability.

To complete its camera portfolio, Dallmeier is now offering a smaller version of the successful 3-megapixel IR camera. The DF4820HD-DN/IR supports resolutions of up to 2 megapixels with the same high image quality and the full range of functions found in the larger model (DF4920HD-DN/IR). With the same scope of delivery including wall bracket, this makes it an ideal starter model for a lower price.

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 realises 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 guaranteed.

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.
