Exclusive expert tips, customer stories and more.
The cameras of the Nightline series have been developed with special attention to changing light conditions for 24-hour video surveillance.
The combination of the most advanced sensor and encoder technology provides recordings with excellent contrast, brilliant clarity as well as highest detail resolution and color fidelity, even in low light conditions. The DDF5250HDV-DN is available with an integrated lens in a vandal-resistant dome housing. It can be conventionally supplied with an external power supply unit or conveniently with Power over Ethernet.
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 camera is 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 a comfortable fine adjustment of the captured image section (horizontal and vertical at 16:9 resolutions, horizontal at 4:3 resolutions) 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.
Video Content Analysis
The integrated Video Content Analysis (VCA) detects movements and objects in the uncompressed image and analyzes them in realtime (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 Dallmeier 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 Dallmeier Client Software with the SmartFinder function.
The camera is equipped with a RAM memory that is used by the EdgeStorage function to store the video stream in case of a network failure (e.g. Spanning Tree, Bursts). When the network is restored, the SmartBackfill function ensures fast transmission to the Dallmeier recording system. This stores the video stream with high speed and then continues to record the live stream seamlessly.
