Hikvision DS-2SE4C225MWG-E(12F0) – TandemVu 4-Inch 2 MP 25X Colorful & IR Network Speed Dome
The Hikvision DS-2SE4C225MWG-E(12F0) is a TandemVu PTZ speed dome that pairs a fixed ColorVu bullet channel with a long-reach 25× zoom PTZ channel on one unit. Specifically, the 2.8 mm bullet channel uses an F1.0 aperture and white-light illumination to hold a constant, colour-lit overview even at night. Meanwhile, the PTZ channel zooms 4.8–120 mm (25× optical, 16× digital), so operators pull in identification-level detail anywhere within that wide view. In addition, both channels use a 1/2.8″ progressive scan CMOS sensor, and DarkFighter technology keeps footage usable in low light. As a result, this dome suits large open sites where a fixed overview and a long zoom both matter.
Furthermore, deep-learning-based human and vehicle classification filters motion events, so the PTZ channel can jump to a preset or trigger a patrol scan instead of chasing false alerts. On top of that, the PTZ channel reaches up to 100 m of IR, while the bullet channel adds up to 30 m of white light for colour night footage. The dome pans a full 360° and tilts -15° to 90° with auto-flip, and stores up to 300 presets across 8 patrol scans. Consequently, the housing carries an IP66 rating with lightning and surge protection, and runs on 12 VDC or PoE+.

Who This Camera Suits Best
- Large open sites needing overview and long-reach zoom – for instance, riverbanks, highways, and railway corridors benefit from the fixed bullet channel holding a colour-lit overview while the PTZ channel zooms in on a specific person or vehicle up to 25×.
- Sites replacing two cameras with one at longer range – since the bullet and PTZ channels share a housing and a single PoE+ run, it suits large compounds and industrial sites that need both context and identification-level zoom without running two separate cameras.
- Scheduled patrol with face capture – with 300 presets, 8 patrol scans, and face capture on the PTZ channel, it suits access points, car parks, and perimeters that need automated sweeps plus closer identification when a person is flagged.
