4MP AcuSense Fixed Dome Network Camera

The Hikvision DS-2CD2143G2-IU is a 4MP AcuSense fixed dome network camera designed for indoor and outdoor security monitoring. It uses a 1/3-inch progressive scan CMOS sensor and provides up to 2688 × 1520 resolution. The camera supports 25 fps in 50 Hz mode and 30 fps in 60 Hz mode at maximum resolution.

Clear Imaging in Challenging Light

Up to 120 dB WDR helps balance bright and dark areas in high-contrast scenes. BLC, HLC, and 3D digital noise reduction further support image clarity in changing lighting conditions. The camera provides color imaging at 0.005 Lux with F1.6 and AGC enabled, while IR illumination supports black-and-white monitoring in low-light environments.

AcuSense Human and Vehicle Classification

Deep-learning-based AcuSense technology helps classify human and vehicle targets for more focused event detection. The camera supports motion detection with target classification, line crossing detection, intrusion detection, face detection, video tampering alarms, and scene change detection. Configured events can trigger recording, image capture, email notification, FTP upload, NAS or memory-card storage, and surveillance-center notification.

Which lens options are available?

The datasheet lists 2.8 mm and 4 mm fixed-focal lens options. The 2.8 mm version provides a wider viewing angle, while the 4 mm version provides a narrower viewing angle.

What AcuSense detection functions are supported?

The camera supports motion detection with human and vehicle classification, line crossing, intrusion, face detection, video tampering alarms, and scene change detection. Configured events can trigger recording, image capture, email, FTP, NAS, memory-card, or surveillance-center actions.
Does the camera support audio?

Yes. The DS-2CD2143G2-IU includes a built-in microphone for real-time audio monitoring. The datasheet does not establish a two-way audio configuration, so external audio output should not be assumed.
