Hikvision DS-2CD2346G2-IU Grey Product Overview
The Hikvision DS-2CD2346G2-IU(2.8mm)(C) in grey is a 4MP AcuSense Powered-by-DarkFighter fixed turret network camera with a built-in microphone. The exact Hikvision base model is DS-2CD2346G2-IU(2.8mm)(C); grey describes the housing finish supplied in this listing rather than changing the camera’s core model code.
Its 1/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520 at 25fps in 50Hz mode or 30fps in 60Hz mode. The fixed 2.8mm F1.4 lens provides a 103° horizontal field of view, while infrared illumination reaches up to 30 metres. AcuSense analytics support human and vehicle classification for compatible motion and perimeter events.
Key Benefits
-
Detailed 4MP monitoring: captures up to 2688 × 1520 for clear live viewing and recorded evidence.
-
Wide 2.8mm view: provides 103° horizontal coverage for entrances, shops, offices and general surveillance areas.
-
DarkFighter low-light imaging: supports useful detail where ambient illumination is limited.
-
30m infrared: provides monochrome monitoring in darkness under manufacturer test conditions.
-
AcuSense classification: supported events can distinguish human and vehicle targets to reduce irrelevant alerts.
-
120dB WDR: helps retain detail where bright and shaded areas appear together.
-
Built-in microphone: records audio without misleadingly implying speaker playback or two-way audio.
-
Protected grey housing: the metal enclosure is rated IP67 for correctly installed indoor or outdoor use.

Detection, Audio and Compatibility
AcuSense can classify human and vehicle targets for supported motion, line-crossing, intrusion, region-entry and region-exit events. Detection performance depends on target size, camera angle, lighting, scene conditions and configuration.
The built-in microphone records audio, but Hikvision does not state a speaker or audio output for this exact model, so it must not be presented as a two-way-audio camera. Confirm NVR 4MP decoding, AcuSense and audio-recording support, PoE capacity, storage-card compatibility and mounting accessories before ordering.
