Hikvision DS-2CD2043G2-LI2U(4mm) - 4MPix IP Bullet Hybrid Light AcuSense camera, LED/IR 40m, microphone, IP67

Intelligent IP bullet camera with 4 MP resolution and advanced AcuSense technology for accurate person and vehicle detection.

The network bullet camera DS-2CD2043G2-LI2U features a 1/3" CMOS sensor with a maximum resolution of 2688 × 1520 px and delivers excellent image quality even in challenging lighting conditions. AcuSense technology, based on deep learning, enables accurate classification and detection of humans and vehicles, significantly reducing false alarms.

The camera is equipped with a Smart Hybrid Light system that integrates infrared and white LED illumination with 4 supplemental lighting modes and a range of up to 40 m. This model features a dual microphone for high-quality real-time audio recording. Thanks to 120 dB true WDR technology, it delivers a clear image even against strong backlight.

Advanced Video Features
The camera supports three independent video streams with H.265/H.264/H.265+/H.264+ compression for the main stream and H.265/H.264/MJPEG for the sub-stream. The bit rate is adjustable in the range of 32 Kbps to 8 Mbps with CBR and VBR modes. ROI (Region of Interest) is available for highlighting selected areas, and Target Cropping for image cropping.

Audio Capabilities
The built-in dual microphone supports compression formats G.711, G.722.1, G.726, MP2L2, PCM, MP3, and AAC-LC with sampling rates of 8/16/32/48 kHz. The noise suppression function ensures clear audio recording even in noisy environments.

Network Features and Storage
The camera supports ONVIF (Profile S, G), ISAPI, and SDK protocols for easy integration into various systems. It allows recording to NAS (NFS, SMB/CIFS) and microSD/SDHC/SDXC memory cards up to 512 GB with support for encryption and card health detection. The ANR (Auto Network Replenishment) function ensures automatic recording recovery upon network connection restoration.

Intelligent Detection
In addition to AcuSense classification, the camera offers face detection, motion detection with object type filtering (person/vehicle), camera tampering detection, and other exceptional events. Perimeter protection allows the configuration of virtual lines and zones with accurate intrusion detection.
