The DF5250HD-DN/IR has been developed with special attention to changing light conditions for 24-hour video surveillance. The combination of the most advanced sensor and encoder technology results in recordings with excellent contrast, brilliant clarity as well as highest detail resolution and color fidelity, even in low light conditions.
Excellent Low-Light characteristics
The extremely high light sensitivity of the sensor and the sophisticated image processing ensure crisp color images even in the dark. In night mode, the camera also provides outstanding results due to the excellent infrared sensitivity.
The cameras are equipped with encoder technology that supports encoding of the video stream according to the H.265 standard. This allows the data rate to be reduced by up to 50% compared to H.264 with the same resolution and image quality. In conjunction with the latest Dallmeier recording systems, a significant reduction in network and storage utilization can be achieved.
Motor-driven varifocal lens with P-Iris
The camera has a motor-driven varifocal lens that is perfectly tuned to the image sensor. The adjustment of zoom, focus and iris is made conveniently using a web browser. The manual lens setting directly at the installation site of the camera is not required.
Digital Image Shift
The Digital Image Shift function allows digital fine alignment of the image section conveniently using a web browser. This ensures a quick and easy installation of the camera. The manual fine alignment of the camera directly at the installation site is not necessary..
Video Content Analysis
The integrated Video Content Analysis (VCA) detects movements and objects in the uncompressed image and analyzes 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. Together 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.
The camera is equipped with encoder technology that enables Video Content Analysis supported by AI (Artificial Intelligence) functions based on neural networks in the camera. This provides a significantly more powerful object classification. After a short training phase, the system finally allows an even more targeted evaluation of the recordings and a more effective use of automatic functions such as lossless and multiple Auto-Tacking.
The camera is equipped with a RAM memory that is used by the EdgeStorage function for storing the video stream in case of a network failure (e. g. Spanning Tree, Bursts). When the network is restored, the SmartBackfill function ensures a fast transmission to the SMAVIA recording system. This stores the video stream with high speed and then continues the recording of the live stream seamlessly.
