New from Dallmeier is an infra-red (IR) camera, the DF4820HD-DN/IR. The German CCTV company is now offering a smaller version of the 3-megapixel IR camera. The product supports resolutions of up to 2 megapixels with the same image quality and the range of functions found in the larger model (DF4920HD-DN/IR). This weather-proof 2-megapixel HD network camera comes with automatic day-night switching and integrated infrared illumination. The product provides real-time Full HD video (1080p/30) using the H.264 codec.
Besides automatic and manual image optimisation functions and 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.
The camera comes with a motor-driven P-Iris megapixel varifocal lens. Focal length (zoom), focus and iris (aperture) can be configured by web browser. The P-Iris control thereby gives a significantly improved image quality compared to conventional DC auto iris lenses, it’s claimed, with contrast, clarity and detail resolution, with a greater depth of field, under almost all lighting, the makers say. A Digital Image Shift function provides for a digital fine alignment of the image section, at installation.
Built into an IP66-rated weather-proof enclosure, the camera is designed for indoor and outdoor use. The camera is operated via Power over Ethernet.
