The Dallmeier DF4910HD-DN/IR is a weather-proof 3-megapixel High-Definition camera with integrated infrared illumination.
It provides real-time Full HD video (1080p/30) using the H.264 codec and 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.
Novel IR lighting concept
Most conventional IR cameras use many small LEDs, arranged circularly around the lens. In contrast, the Dallmeier DF4910HD-DN/IR uses three large high-performance light-emitting diodes. The camera thus achieves a very high irradiation output, which means that even at a distance of 25 m details are still clearly recognisable. Additionally, integrated collimators provide for a highly even and homogenous illumination. They ensure that the marginal areas of an image are sufficiently illuminated – which is a huge challenge for conventional IR cameras. So the Dallmeier IR camera features two important advantages: a high irradiation output and a homogenous illumination of boundary areas.
The fast (large maximum aperture) and motor-driven megapixel varifocal lens (F1.0 / 2.8 – 11 mm) allows to adjust the focal length and the focus conveniently via web browser. The camera is operated via PoE which allows for an easy, quick and cost-effective installation.
