Hikvision DS-2CD2043G2-LI2U (2.8mm) — 4MP IP Camera with Microphone

A solution designed for professional surveillance systems, focusing on precise detection and high image quality. The Hikvision DS-2CD2043G2-LI2U network camera offers 4 MP (2688 × 1520 px) resolution at a frame rate of 25/30 fps, ensuring sharp images even in challenging lighting conditions. AcuSense technology, powered by deep learning, minimizes false alarms by accurately detecting people and vehicles. Additionally, it is equipped with a dual microphone for clear audio recording. With an IP67 ingress protection rating, it is suitable for outdoor use in extreme conditions. ### Advanced Imaging and Illumination Technologies

Image quality is ensured by a 1/3" CMOS sensor and 120dB true WDR technology, which provides a clear image even in backlit conditions. The camera features a Smart Hybrid Light system with IR and white LED illumination reaching up to 40 m, guaranteeing reliable surveillance even in total darkness. Supplementary illumination modes allow the camera to be adapted to various scenarios.

Efficient Compression and Storage

Efficient operation is ensured through support for H.265+ compression, which saves both storage space and bandwidth. The camera supports recording to a microSD/SDHC/SDXC memory card (up to 512 GB capacity) and network-attached storage (NAS via NFS, SMB/CIFS). It also includes the ANR (Auto Network Replenishment) function, which automatically fills in recording gaps in the event of a network failure.

Audio and Intelligent Detection

A built-in dual microphone provides high-quality audio recording with ambient noise cancellation. The camera supports multiple audio formats—including G.711, MP2L2, AAC-LC, and others—with a sampling rate of up to 48 kHz. AcuSense technology enables the detection of moving people and vehicles, while perimeter protection allows for the configuration of virtual lines and zones for precise intrusion detection.
