Hikvision DS-2CD2346G2H-IU Product Overview
The Hikvision DS-2CD2346G2H-IU(2.8mm)(eF) is a 4MP AcuSense Powered-by-DarkFighter fixed turret network camera with a built-in microphone. Its 1/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the fixed 2.8mm F1.0 lens provides a wide 100.2° horizontal field of view.
The camera combines a manufacturer-rated minimum colour illumination of 0.001 lux, infrared illumination up to 30 metres and 120dB WDR. Deep-learning analytics support human and vehicle classification for compatible motion and perimeter events. It also provides face capture, scene-change detection and local memory-card support up to 512GB. Hikvision does not state a built-in speaker, external audio input/output or alarm input/output for this exact IU model.
Key Benefits
-
Detailed 4MP video: records at up to 2688 × 1520 at 25fps in 50Hz mode or 30fps in 60Hz mode.
-
Wide scene coverage: the fixed 2.8mm lens provides a 100.2° horizontal view.
-
DarkFighter low-light imaging: the F1.0 aperture supports useful colour detail in very low illumination.
-
Infrared night monitoring: built-in 850nm IR has a manufacturer-rated range of up to 30 metres.
-
AcuSense classification: supported events can distinguish human and vehicle targets.
-
Backlight handling: 120dB WDR helps retain detail where bright and dark areas appear together.
-
Built-in audio capture: the integrated microphone records sound without implying speaker playback.
-
Protected metal housing: the enclosure is rated IP67 for water and dust resistance.

Detection and Low-Light Imaging
Powered-by-DarkFighter technology and the F1.0 lens support colour imaging where ambient light is limited. When the available light is insufficient, the infrared illuminator provides monochrome imaging. Hikvision specifies an IR range of up to 30 metres, although practical performance depends on mounting, surfaces and scene conditions.
AcuSense can classify human and vehicle targets for supported motion, line-crossing, intrusion, region-entry and region-exit events. Face capture and scene-change detection are also available. Detection performance depends on target size, camera angle, lighting and correct configuration.
Audio, Storage and Compatibility
The camera has a built-in microphone for audio capture. No built-in speaker or audio output is stated, so this listing does not claim two-way audio. The internal slot supports compatible microSD-family cards up to 512GB; a card is normally sold separately.
Confirm NVR 4MP decoding, AcuSense support, audio recording, PoE capacity, memory-card compatibility and the required mounting accessory before ordering. ONVIF support can assist third-party integration, but it does not guarantee access to every Hikvision analytics or audio feature.
