Hikvision DS-2CD23126G3-I2UY 12MP 2.8mm AcuSense Darkfighter Fixed Turret IP Camera with Mic BLACK

Overview

The Hikvision DS-2CD23126G3-I2UY(2.8MM)/B is the 12 MP fixed turret in the Hikvision G3 "Powered by DarkFighter" range, finished in matte black for installations that benefit from a less visible camera (designer interiors, dark soffits, modern building facades). The 1/1.8-inch Progressive Scan CMOS delivers 4608 × 2592 imaging (up to 20 fps at full resolution, 30 fps stepped down to 4K) with 0.0008 Lux @ (F1.6, AGC ON) minimum colour illumination at F1.6 and 0 Lux performance with IR. Hikvision's DarkFighter sensor and image-signal processing dramatically improve low-light noise and detail retention compared with standard low-light cameras.

Smart IR supplement light up to 40 m (850 nm) with intelligent supplement-light switching minimises light pollution while ensuring usable detail at night. 130 dB true WDR captures both bright and shaded areas of high-contrast scenes (back-lit doorways, vehicle headlights, sunset car parks). The Hikvision image-engine offers 3D DNR, BLC, HLC, defog, distortion correction, EIS image stabilization, white-balance adjustment, 4 polygon privacy masks and ROI-aware bit-rate control.

AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide deep-learning analytics filter human and vehicle classifications on Line Crossing, Intrusion, Region Entrance and Region Exit events — reducing false alarms from foliage, wildlife or weather by approximately 90% compared with simple motion detection. Face Capture, scene-change detection, video-tampering and motion exception events are also supported on-camera. Multi-codec output (H.265+ / H.264+ / H.265 / H.264 / MJPEG) up to 24 Mbps with main stream + sub-stream + (under certain settings) third stream gives flexibility for VMS integration. ONVIF Profile S/G/T, ISAPI, SDK and ISUP supply integration with third-party VMS / NVR; first-party Hikvision iVMS-4200 desktop, Hik-Connect mobile and Hik-Central enterprise platforms are fully supported.

The 12 MP turret runs on PoE 802.3af Class 3 (max 10.5 W) or 12 VDC 0.7 A (max 8.5 W) and includes microSD on-board storage up to 512 GB with Auto Network Replenishment (ANR). Built-in arrayed dual-microphone captures real-time audio. The metal chassis is IP67 ingress-protected and NEMA 4X moderate-level anti-corrosion (suitable for coastal areas up to 2 km from coastlines, and acid-rain affected sites). Operating range is -30 °C to 60 °C with humidity ≤ 95% non-condensing.
