Hikvision DS-2CD2143G2-LIS2U(2.8mm) - 4MPix IP Dome camera; IR 30m, Audio, Alarm, IP67, IK10

IP fixed dome camera with 4 MP resolution (2688 × 1520 px), 2.8 mm lens, and Smart Hybrid Light technology combining IR and white light illumination.

The camera utilizes AcuSense technology based on deep learning, which enables classification of moving objects as persons or vehicles. This significantly reduces false alarms and improves the accuracy of perimeter intrusion detection. The Smart Hybrid Light feature offers four supplemental lighting modes with a range of up to 30 m – IR illumination (850 nm) and white light can be combined according to current conditions.

The -2U variant is equipped with a built-in dual microphone array for real-time audio recording. The camera supports H.265+ compression for efficient data transmission and 120 dB WDR technology for clear imaging even in strong backlight conditions. 

Detection and Events
The camera supports basic motion detection with the ability to trigger alarms for specified target types (persons, vehicles), tamper detection, and exceptions. Perimeter protection functions include intrusion detection and virtual line crossing with alarms limited to persons or vehicles. Face detection is available as a smart event.

Network and Security
The camera supports TCP/IP, HTTPS, RTSP, ONVIF (Profile S, Profile G), ISAPI, and ISUP protocols. Security features include HTTPS encryption, IP address filtering, TLS 1.1/1.2/1.3 protocol, security event auditing, and WSSE authentication. Up to 6 simultaneous live streams can be viewed; the camera supports up to 32 user accounts across three permission levels.

Recording Storage
Recordings can be stored locally on a microSD/microSDHC/microSDXC memory card (up to 512 GB) or on a NAS network storage (NFS, SMB/CIFS) with support for Automatic Network Replenishment (ANR). Together with a compatible Hikvision memory card, card encryption and health monitoring are supported.
