TandemVu Panoramic and PTZ Surveillance
The Hikvision DS-2SF8C825MXG2/LM-ELWY/26 is a DeepinViewX TandemVu 8C Series panoramic network speed dome that combines a panoramic bullet channel with a 25× PTZ channel. This dual-channel design allows the camera to monitor a wide area while the PTZ channel provides detailed observation of selected targets. The bullet channel provides up to 6MP resolution, while the PTZ channel provides up to 8MP resolution.
Wide-Area Coverage with Long-Range Zoom
The panoramic channel provides a horizontal field of view of 190° ± 10° and adjustable vertical tilt from 12° to 24°. The PTZ channel supports 360° pan movement, -20° to 90° tilt movement, 25× optical zoom, and 16× digital zoom. It provides up to 300 presets, 8 patrols with up to 32 presets per patrol, and 4 pattern scans for flexible monitoring of large sites.
DarkFighter 2.0 and Hybrid Illumination
DarkFighter 2.0 technology supports 24/7 colorful imaging and low-light monitoring. The panoramic channel combines white light and IR illumination, with white light up to 40 m and IR up to 60 m. The PTZ channel provides IR illumination up to 400 m. Smart supplement light adjusts the illumination according to the monitoring scene.
AI-Based Security and Traffic Analysis
The camera supports large-scale AI model functions for perimeter protection, including line crossing, intrusion, region entrance, and region exiting detection. Human and vehicle target filtering helps focus alarms on relevant objects. Depending on the configured function, the camera also supports face capture, face comparison, vehicle attributes, license plate recognition in checkpoint scenarios, vehicle counting, people-density detection, and object tracking.

| Scenario-Aware Object Detection | |
| This function is based on the large model technology combined with image classification detection. It can automatically detect and identify scene categories in the detection area, including road, intersection, toll station, petrol station, open-air square, vehicle entrance and exit, and person entrance and exit, etc. The PTZ camera will rotate 360° to capture and label the scenes.For automatically recognize the scene information of captured image.- Real-time detection mode: the PTZ camera completes the full-scene capture, detection, and recognition output within 10 minutes in 360°.- Scheduled detection mode: the scheduled time can be set, and pictures can be collected every day or week. The collected pictures will be stored in eMMC, and the detection results will be output at 2 AM by default.The detection results and labels can be uploaded as alarms, and the alarm should include the camera IP address, port No., channel No., capture time, upload time, picture, PTZ coordinates, label ID, label name, and OCR information, as well as the coordinates of each OCR. | |
