New from the German manufacturer Dallmeier is the DF5400HD-DN/IR, an infrared (IR) camera. It’s designed specifically for applications requiring images with highest resolution in real-time at day and in the IR mode at night, the makers say.
The DF5400HD-DN/IR is an Ultra HD camera with IR illumination. Built into an IP66-rated weather-proof enclosure, the camera is for indoor and outdoor applications, according to the firm. At cabling and commissioning, the camera is operated with Power over Ethernet (PoE Class 0, IEEE 802.3af).
The high resolution of the sensor and the image processing enable real-time recordings with UHD resolution at a frame rate up to 25/30 fps (2160p/30). Thus, the camera is the makers say suited when capturing detail in real time. The camera comes with an ambient light sensor and a removable IR cut filter and can automatically switch between day and night mode. In addition, different day and night presets for the exposure settings can be defined and adjusted.
The automatic Day/Night operation is supported by a uniform IR illumination by means of semi-covert 850 nm high power LEDs.
The camera has a motor-driven megapixel varifocal lens that is tuned to the image sensor. The adjustment of zoom, focus and iris is made using a web browser. The manual lens setting directly at the installation site of the camera is not required. The lens comes with a P-Iris control providing a precise and automatic adjustment of the optimum aperture. Thus, the camera achieves a much better depth of field than with conventional DC auto iris lenses under almost any lighting it is claimed.
The Digital Image Shift function allows fine adjustment of the captured image section via a web browser. Depending on the selected resolution, the used area on the image sensor can be moved and adapted to the local conditions. The manual fine alignment of the camera directly at the installation site is not necessary.
Storage
The camera has a RAM memory that is used by the EdgeStorage function for storing the video stream in case of a network failure. When the network is restored, the SmartBackfill function allows transmission to the SMAVIA recording system. This stores the video stream and then continues the recording of the live stream.
