The Hikvision DS-2CD2046G2H-I2U/SL is a 4MP AcuSense fixed bullet IP camera with two-way audio, white strobe light warning, human and vehicle classification, up to 40m IR night vision, 120dB WDR, H.265+ compression, PoE support, microSD storage up to 512GB and IP67 weather protection.

The Hikvision DS-2CD2046G2H-I2U/SL is a professional 4MP AcuSense strobe light and audible warning fixed bullet network camera, designed for accurate CCTV monitoring and active deterrent security.

With 4MP high-resolution imaging up to 2688 × 1520, this camera captures clear and detailed footage for homes, shops, offices, warehouses, yards, entrances, driveways and commercial premises. Its bullet-style design makes it suitable for visible security installations where strong deterrence is needed.

The camera uses Hikvision AcuSense technology to focus on human and vehicle classification, helping reduce false alarms caused by irrelevant movement such as leaves, animals or weather conditions. This makes alerts more useful and helps security teams or property owners respond faster to real activity.

For active security response, the DS-2CD2046G2H-I2U/SL includes built-in two-way audio, 2 built-in microphones, a built-in speaker, and white strobe light warning. When an event is triggered, the camera can help warn intruders using audible warning and flashing light deterrence.

The camera also performs well in difficult lighting conditions thanks to 120dB WDR, helping improve visibility where bright and dark areas appear in the same scene. Built-in IR night vision up to 40m supports clear monitoring in low-light and night-time environments.

With H.265+ compression, the camera helps reduce bandwidth and storage usage while maintaining high-quality video. It also supports microSD card storage up to 512GB, giving flexible edge recording options.

The IP67-rated metal housing provides water and dust resistance, making this camera suitable for indoor and outdoor CCTV installations. PoE support allows both power and data through one network cable for a cleaner and easier installation.
