The DS-2CD2343G2-IU is a 4MP AcuSense fixed turret network camera designed for commercial surveillance applications that require intelligent event filtering, reliable outdoor performance, and built-in audio recording. With 2688 × 1520 resolution, it provides clear video for entrances, storefronts, warehouses, office buildings, parking access points, and business perimeter locations.
AcuSense technology focuses on human and vehicle target classification, helping reduce unnecessary alerts caused by weather, animals, or general background motion. This makes the camera a practical option for businesses that need more accurate event detection around access points, exterior doors, and perimeter areas.
The built-in microphone adds real-time audio recording for improved situational awareness through compatible surveillance systems. Combined with 120 dB Wide Dynamic Range, Smart IR illumination up to 30 meters, and image enhancement features, the camera supports dependable day and night monitoring in challenging commercial scenes.
With H.265+ compression, onboard microSD storage up to 512 GB, ONVIF Profile S/G support, PoE deployment, and IP67 weather protection, the DS-2CD2343G2-IU is built for professional security installations where video detail, intelligent detection, and audio awareness are important.
