Hikvision DS-2CD2387G3-LI2UY 2.8mm Product Overview
The Hikvision DS-2CD2387G3-LI2UY(2.8mm) is an 8MP ColorVu Smart Hybrid Light fixed turret network camera with an arrayed dual microphone. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 3840 × 2160, while the fixed 2.8mm F1.0 lens provides a wide 108.8° horizontal field of view.
The camera combines infrared and white-light illumination up to 30 metres with 130dB WDR and person and vehicle classification for supported events. It also provides face capture, scene-change detection and local memory-card support up to 512GB. This exact LI2UY model has dual microphones for audio capture, but Hikvision does not state a built-in speaker, external audio input/output or alarm input/output, so it must not be presented as a two-way-audio or active-deterrence camera.
Key Benefits
-
4K 8MP monitoring: captures up to 3840 × 2160 at 25fps in 50Hz mode or 30fps in 60Hz mode.
-
Wide 2.8mm coverage: the 108.8° horizontal view suits broad entrances, shops, offices, yards and general surveillance areas.
-
ColorVu low-light imaging: the large sensor and F1.0 aperture support colour-focused detail where ambient illumination is limited.
-
Smart Hybrid Light: provides configurable infrared and white-light operation with a manufacturer-rated range of up to 30 metres.
-
Person and vehicle classification: supported events can focus on selected target types to reduce irrelevant alerts.
-
130dB WDR: helps retain detail where bright and shaded areas appear together.
-
Arrayed dual microphone: captures audio without misleadingly implying speaker playback.
-
Protected metal housing: IP67 and NEMA 4X provide weather resistance and moderate anti-corrosion protection.

Night Imaging and Detection
Smart Hybrid Light can use infrared, white light or an intelligently controlled combination according to configuration. ColorVu supports colour-focused low-light monitoring, although practical results depend on scene illumination, reflective surfaces, mounting and camera settings.
Person and vehicle classification is available for supported motion, line-crossing, intrusion, region-entry and region-exit events. Face capture and scene-change detection are also supported. Detection performance depends on target size, camera angle, lighting and correct configuration.
Audio, Storage and Compatibility
The arrayed dual microphone provides audio capture. No speaker or audio output is stated for this exact model, so the listing does not claim two-way audio. The internal card slot supports compatible cards up to 512GB; a memory card is normally sold separately.
Confirm NVR 8MP decoding, analytics, audio recording, Smart Hybrid Light controls, PoE capacity, storage-card support and mounting accessories before ordering. ONVIF support can assist third-party integration but does not guarantee every Hikvision-specific feature.
