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.

FAQ

What is the difference between the two camera channels?

The panoramic bullet channel provides wide-area coverage with up to 6MP resolution, while the PTZ channel provides up to 8MP resolution, 25× optical zoom, and 16× digital zoom. The two channels can work together to monitor a broad scene and inspect selected targets in greater detail.

How far can the PTZ channel illuminate at night?

The PTZ channel provides IR illumination up to 400 m according to the datasheet. The actual monitoring result depends on target size, environmental conditions, installation height, atmospheric visibility, and scene configuration.

The PTZ channel provides IR illumination up to 400 m according to the datasheet. The actual monitoring result depends on target size, environmental conditions, installation height, atmospheric visibility, and scene configuration.

The panoramic channel supports white light and IR illumination. The specified range is up to 40 m for white light and up to 60 m for IR. Smart supplement light can adjust the lighting according to the monitoring scene.

Does the camera support license plate recognition?

Yes. License plate recognition for vehicles and motorcycles is supported in checkpoint scenarios. The datasheet also lists vehicle attribute detection, vehicle and non-vehicle counting, blocklist and allowlist management, and regional license plate recognition support. The exact performance depends on installation and lighting conditions.
