Hikvision DS-2CD2047G2-LU 4MP ColorVu AcuSense Bullet IP Camera with Built-in Microphone

The Hikvision DS-2CD2047G2-LU is a 4MP ColorVu bullet IP camera designed for continuous full-color surveillance with integrated audio and intelligent analytics. It uses a high-sensitivity 1/1.8-inch CMOS sensor combined with an F1.0 aperture lens to deliver bright and detailed images even in extremely low-light environments without relying solely on infrared illumination. The compact bullet design supports outdoor installation with strong durability against weather and tampering. AcuSense technology improves detection accuracy by distinguishing human and vehicle movement from irrelevant motion, reducing false alarms and improving monitoring efficiency. The camera also supports efficient compression, wide dynamic range imaging, and flexible storage options for professional security deployments.
