Hikvision DS-2CD2346G3-IZ2UY Product Overview
The Hikvision DS-2CD2346G3-IZ2UY(2.8/4mm) is a 4MP AcuSense Powered-by-DarkFighter point-varifocal turret network camera with an arrayed dual microphone. Its motorised lens can switch between the supported 2.8mm and 4mm focal positions, allowing the installer to choose either a wider overview or a tighter view without manually opening the camera.
The 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, local storage up to 512GB and IP67 plus NEMA 4X protection.
Key Benefits
-
Selectable 2.8mm or 4mm view: motorised point-varifocal adjustment lets the installer choose between two defined focal positions.
-
Detailed 4MP video: captures up to 2688 × 1520 at up to 25/30fps.
-
DarkFighter low-light imaging: supports useful detail under limited illumination.
-
30m infrared: provides monochrome night monitoring in darkness.
-
AcuSense classification: supported events can distinguish human and vehicle targets.
-
130dB WDR: helps preserve detail in high-contrast scenes.
-
Arrayed dual microphone: provides integrated audio capture without implying speaker playback.
-
Protected metal housing: IP67 and NEMA 4X support exposed installations and moderate anti-corrosion protection.

Understanding the Point-Varifocal Lens
This is not a continuous zoom lens. It provides two selectable focal positions: 2.8mm for a wider scene and 4mm for a tighter view. The motorised mechanism supports remote switching and focus adjustment between those defined positions. Confirm the required field of view during commissioning.
Analytics, Audio and Compatibility
AcuSense supports human and vehicle classification for compatible motion and perimeter events. The arrayed dual microphone captures audio, but no speaker or audio output is stated, so this product is not presented as a two-way-audio camera.
Confirm NVR 4MP decoding, AcuSense, audio recording, lens control, PoE, storage-card and mounting compatibility before ordering. NEMA 4X indicates moderate anti-corrosion protection and does not make the camera suitable for every severe marine or chemical environment.
