Hikvision DS-2CD2386G2H-IU 4mm Product Overview
The Hikvision DS-2CD2386G2H-IU(4mm)(eF) is an 8MP AcuSense Powered-by-DarkFighter fixed turret network camera with a built-in microphone and a narrower fixed 4mm lens. Its 1/1.8-inch progressive-scan CMOS sensor records at up to 3840 × 2160, while the F1.0 lens provides a 93.3° horizontal field of view.
The camera combines a manufacturer-rated minimum colour illumination of 0.0008 lux, infrared illumination up to 30 metres and 120dB WDR. AcuSense 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
-
4K 8MP detail: records at up to 3840 × 2160 for detailed monitoring and playback.
-
Tighter 4mm view: the 93.3° horizontal field of view gives narrower framing than the 2.8mm version and makes subjects appear larger at the same distance.
-
DarkFighter low-light imaging: the 1/1.8-inch sensor and F1.0 aperture support useful colour detail where ambient light is limited.
-
30m infrared: provides monochrome monitoring in darkness under manufacturer test conditions.
-
AcuSense classification: supported events can distinguish human and vehicle targets.
-
120dB WDR: helps preserve detail in strongly backlit scenes.
-
Built-in microphone: records audio without implying speaker playback or two-way audio.
-
IP67 protection: supports correctly installed indoor or outdoor use.

Choosing the 4mm Lens
The 4mm lens provides a narrower field of view than the 2.8mm version, so subjects appear larger at the same distance while the camera covers less width. It can suit a defined doorway, path, gate, till area or target zone. The lens is fixed and cannot zoom remotely, so the required view should be confirmed before ordering.
Detection, Audio and Compatibility
AcuSense can classify human and vehicle targets for supported motion and perimeter events. The built-in microphone records audio, but no speaker or audio output is stated, so the camera is not presented as a two-way-audio model.
Confirm NVR 8MP decoding, required frame rate, AcuSense and audio-recording support, PoE capacity, storage-card compatibility and mounting accessories before ordering.
