Hikvision DS-2CD2346G3-IZ2UY(2.8/4mm)(BLACK) Product Overview
The Hikvision DS-2CD2346G3-IZ2UY(2.8/4mm)(BLACK) is the official black version of Hikvision’s 4MP AcuSense Powered-by-DarkFighter point-varifocal turret network camera. Its motorised lens provides two defined focal positions—2.8mm for wider coverage and 4mm for tighter framing—rather than a continuously variable optical zoom.
A 1/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520 at 25fps in 50Hz mode or 30fps in 60Hz mode. The camera also provides infrared illumination up to 30 metres, 130dB WDR, human and vehicle classification, face capture, an arrayed dual microphone, local memory-card support up to 512GB and a black metal housing rated IP67 and NEMA 4X.
Key Benefits
-
Official black model: the exact manufacturer notation is DS-2CD2346G3-IZ2UY(2.8/4mm)(BLACK).
-
Selectable field of view: switch remotely between the wider 2.8mm position and the tighter 4mm position.
-
Detailed 4MP video: records up to 2688 × 1520 at 25/30fps.
-
DarkFighter imaging: supports useful image detail in low illumination.
-
AcuSense classification: compatible events can distinguish human and vehicle targets.
-
30m infrared: supports monochrome monitoring in darkness.
-
Integrated audio capture: the arrayed dual microphone records sound without implying speaker playback.
-
Protected housing: IP67 and NEMA 4X provide weather resistance and moderate anti-corrosion protection.

Point-Varifocal Lens Guidance
The lens is not a continuous zoom. It switches between the defined 2.8mm and 4mm positions with motorised focus adjustment. The 2.8mm setting covers more width, while the 4mm setting gives tighter framing. Confirm the required scene coverage during commissioning.
Audio, Analytics and Compatibility
The arrayed dual microphone provides audio capture, but Hikvision does not state a speaker or audio output for this exact model, so it must not be sold as a two-way-audio camera. AcuSense classification can focus compatible motion and perimeter events on human and vehicle targets.
Confirm NVR 4MP decoding, lens-control support, AcuSense compatibility, audio recording, PoE capacity, storage-card support and mounting accessories before ordering. NEMA 4X indicates moderate anti-corrosion protection rather than unrestricted suitability for every severe marine or chemical environment.
