Hikvision DS-2DE5425IWG1-E(B) DarkFighter Acusense Network Speed Dome, 4MP, 25× Optical Zoom

What it does

The DS-2DE5425IWG1-E(B) is a 4 MP 25X network speed dome powered by DarkFighter with Acusense. A 1/2.8" Progressive Scan CMOS gives 4 MP resolution (2560 × 1440), and the 4.8 mm to 120 mm lens provides 25× optical zoom and 16× digital zoom.

IR supplement light reaches up to 150 m, and minimum illumination is Color: 0.005 Lux @ (F1.6, AGC ON); B/W: 0.001 Lux @ (F1.6, AGC ON), 0 Lux with IR.

The camera focuses on human and vehicle targets classification based on deep learning, detects up to 5 faces simultaneously for face capture, and supports manual tracking and auto-tracking.

HIK AI-ISP handles noise reduction, and self-learning focus technology gives high focus speed. Image tools include WDR, HLC, BLC, 3D DNR, defog, regional exposure and regional focus.
