Hikvision DS-2CD2346G3D-IZ2UY/SL(2.8/4mm)(BLACK) Overview
The Hikvision DS-2CD2346G3D-IZ2UY/SL(2.8/4mm)(BLACK) is the official black version of Hikvision’s dual-lens 4MP AcuSense Powered-by-DarkFighter turret network camera. It provides two independent video channels through one Ethernet connection and one IP address. Each channel uses its own 1/3-inch progressive-scan CMOS sensor and records at up to 2688 × 1520.
Each channel has an independently controlled motorised point-varifocal lens with two defined focal positions: 2.8mm for wider coverage and 4mm for tighter framing. The /SL hardware also includes an arrayed dual microphone, a 1.5W speaker, a white warning strobe and audible-warning capability for compatible two-way audio and active deterrence.
Key Benefits
-
Two independent 4MP channels: monitor two areas from one camera body without misleadingly describing the product as one combined 8MP stream.
-
One network cable and IP address: simplifies installation and device management compared with two separate cameras.
-
Independent lens selection: each channel can use the wider 2.8mm position or the tighter 4mm position.
-
AcuSense classification: supported events can distinguish human and vehicle targets.
-
DarkFighter imaging and 30m IR: support low-light and night monitoring.
-
Integrated two-way audio: dual microphones and a 1.5W speaker support compatible communication.
-
Active deterrence: a white warning strobe and audible warning can be linked to supported events.
-
Protected black housing: IP67 and NEMA 4X provide weather resistance and moderate anti-corrosion protection.

Understanding the Dual-Lens Design
This camera supplies two separate 4MP channels rather than one combined 8MP image. Both channels share one network connection and one IP address, but the recorder must still support the multi-sensor device and have sufficient channel and decoding capacity.
The two lenses can be aimed and configured independently. The 2.8mm position provides broader coverage, while the 4mm position provides tighter framing. The lens mechanism switches between those two defined focal positions; it is not a continuously variable optical zoom.
Audio, Deterrence and Compatibility
The arrayed dual microphone and 1.5W speaker support compatible two-way audio. The white warning strobe and audible warning can be linked to supported events. External audio and alarm input/output are not stated for this exact model and are therefore not claimed.
Confirm NVR multi-sensor support, available channel capacity, 4MP decoding for both channels, AcuSense compatibility, point-varifocal control, PoE+ capacity, two-way audio, deterrence functions, memory-card support and mounting requirements before ordering.
Frequently Asked Questions
Is this the official black version?
Yes. The exact manufacturer notation is DS-2CD2346G3D-IZ2UY/SL(2.8/4mm)(BLACK).
Does it provide one 8MP stream?
No. It provides two independent 4MP channels, each recording at up to 2688 × 1520.
How many IP addresses does it use?
One IP address is used for both channels.
Can each lens be configured separately?
Yes. Each channel can independently use the supported 2.8mm or 4mm position.
