The Hikvision DS-2CD2443G2-IW (2.8mm) is a 4MP AcuSense Wi-Fi Fixed Cube Network Camera designed for intelligent indoor surveillance in homes, offices, retail stores, classrooms, banks, and small businesses. Equipped with a 1/3-inch Progressive Scan CMOS image sensor, it captures sharp 2560 × 1440 (4MP) resolution video with excellent low-light performance. The 2.8 mm fixed lens provides a 92° horizontal field of view, making it ideal for monitoring wide indoor areas with minimal blind spots. Built-in 2.4 GHz Wi-Fi (IEEE 802.11 b/g/n) enables flexible wireless installation while AcuSense technology uses deep learning algorithms to accurately detect human targets, reducing false alarms caused by irrelevant motion.

The camera features built-in two-way audio with an integrated microphone and speaker, allowing real-time communication through the Hik-Connect app or compatible Hikvision recorders. A Passive Infrared (PIR) sensor provides reliable human motion detection, while EXIR infrared illumination offers clear night vision up to 10 meters. Advanced imaging technologies such as DWDR, 3D Digital Noise Reduction (3D DNR), and H.265+ video compression optimize image quality and reduce bandwidth and storage requirements. The camera also supports microSD cards up to 512 GB, Power over Ethernet (PoE), and 12 VDC power, making it a versatile solution for modern indoor security applications.
