Description
Hikvision DS-2CD2347G3-LI2UY 4mm Product Overview
The Hikvision DS-2CD2347G3-LI2UY(4mm) is a 4MP ColorVu Smart Hybrid Light fixed turret network camera with an arrayed dual microphone and a narrower fixed 4mm lens. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the F1.0 lens provides a 95.2° horizontal field of view.
The camera combines infrared and white-light illumination up to 30 metres with 130dB WDR and human and vehicle classification for supported events. It also provides face capture, scene-change detection and local storage up to 512GB. This exact LI2UY version records audio through its dual microphones but does not have a manufacturer-stated speaker, external audio input/output or alarm input/output.
Key Benefits
-
Detailed 4MP monitoring: captures up to 2688 × 1520 at 25fps in 50Hz mode or 30fps in 60Hz mode.
-
Tighter 4mm view: the 95.2° horizontal field of view gives narrower framing than the 2.8mm model.
-
ColorVu low-light imaging: the large sensor and F1.0 aperture support colour-focused detail under limited illumination.
-
Smart Hybrid Light: provides configurable infrared and white-light operation up to 30 metres.
-
Human and vehicle classification: supported events can focus on the selected target types.
-
130dB WDR: supports high-contrast entrances and backlit scenes.
-
Arrayed dual microphone: provides integrated audio capture without implying speaker playback.
-
Protected housing: IP67 and NEMA 4X support exposed installations and moderate anti-corrosion protection.

Choosing the 4mm Lens
The 4mm lens provides a narrower view than the 2.8mm option, making subjects appear larger at the same distance while covering less width. It can suit defined entrances, paths or target areas. The lens is fixed and cannot zoom remotely, so the required field of view should be confirmed before ordering.
Audio and Compatibility
The dual microphones provide audio capture. No speaker or audio output is stated, so the page does not claim two-way audio. Confirm NVR 4MP decoding, analytics, Smart Hybrid Light control, audio recording, PoE, storage and mounting compatibility.
