IR network camera

A new high definition IR network camera from Dallmeier is the DF5210HD-DN/IR. The infrared camera has been developed for changing lighting conditions for 24-hour use, the German manufacturer says.

The high light sensitivity of the sensor and the image processing ensure crisp colour images even in the dark, according to the company. In night mode, the camera also provides results due to the infrared sensitivity. The camera comes with an ambient light sensor and a removable IR cut filter and can automatically switch between day and night mode. 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 the makers say tuned to the image sensor. The adjustment of zoom, focus and iris is made via a web browser. The manual lens setting at the installation site of the camera is not required.

The Digital Image Shift function allows fine adjustment of the captured image section (horizontal and vertical at 16:9 resolutions, horizontal at 4:3 resolutions) via a web browser for installation of the camera. Depending on the selected resolution, the used area on the image sensor can be moved and adapted to the local conditions.

Video Content Analysis

The integrated Video Content Analysis (VCA) detects movements and objects in the uncompressed image and analyses them in real-time (depending on the analysis resolution) with highly developed analysis functions such as Intrusion Detection or Line Crossing. The detected events can be used to trigger the recording of a SMAVIA recording system. With the detected objects and the corresponding metadata, they are stored in a database. This allows the targeted search and evaluation of the recordings by SMAVIA Viewing Client with the function SmartFinder. And the camera comes with 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 ensures transmission to the SMAVIA recording system. This stores the video stream with high speed and then continues recording of the live stream.
