HK-311324131 specification sheet

Overview:

The Hikvision DS-2CD2146G2H-I(SU) is a 4MP powered-by-DarkFighter fixed dome network camera designed for reliable security monitoring in challenging lighting conditions. It combines 4MP image quality with advanced low-light performance, 120 dB true WDR, efficient H.265+ compression and intelligent human and vehicle target classification. The camera also includes a built-in microphone for real-time audio monitoring, while its IP67 water and dust resistance and IK10 vandal resistance make it suitable for demanding indoor and outdoor security installations.

Description:

The Hikvision 4MP DarkFighter fixed dome camera provides detailed surveillance footage while maintaining image clarity when lighting conditions are poor or uneven. Its 2.8mm fixed lens provides a practical viewing angle for monitoring entrances, corridors, offices, retail areas, commercial properties and other security-sensitive locations.

Powered by DarkFighter technology, the camera is designed to deliver improved imaging in low-light environments. True 120 dB WDR helps balance bright and dark areas within the same scene, making it easier to identify people and objects when strong backlighting is present. Intelligent deep learning technology can also distinguish between human and vehicle targets, helping reduce unwanted detection events.

The camera supports up to 30 m IR illumination for nighttime monitoring and uses H.265, H.264, H.265+ and H.264+ video compression to help reduce bandwidth and storage requirements. A built-in memory card slot supports cards up to 512 GB, providing an additional recording option for suitable installations.

Features:

4MP Hikvision DarkFighter Camera for Low-Light Security
With a maximum resolution of 2688 x 1520, the camera captures detailed video for day and night surveillance. DarkFighter technology enhances performance in low-light conditions, while 3D DNR helps reduce image noise for cleaner footage.

Key imaging capabilities include:

• 4MP resolution up to 2688 x 1520
• Powered-by-DarkFighter low-light imaging
• 2.8mm fixed lens
• Up to 30 m IR illumination range
• 120 dB true WDR
• BLC and HLC for difficult lighting conditions
• 3D DNR for noise reduction

Intelligent Detection and Security Monitoring
The camera provides intelligent security functions designed to improve monitoring efficiency. Deep learning technology supports human and vehicle target classification, while motion detection and face capture provide additional options for security applications. Perimeter protection can help monitor defined areas and identify relevant activity.

The camera supports up to six simultaneous live view channels and provides one fixed region for the main stream and sub-stream region of interest. These functions allow users to configure monitoring and recording according to the requirements of the installation.

Efficient Video Compression and Storage
Hikvision H.265+ compression helps reduce the amount of bandwidth and storage required for video recording without unnecessarily compromising image quality. The camera also supports H.265, H.264 and H.264+ compression formats for compatibility with different recording and surveillance systems.

A built-in memory card slot supports storage media up to 512 GB, providing an additional local recording option where required.

Network Connectivity and Installation
The camera includes a 10M/100M self-adaptive RJ45 Ethernet port for network connectivity. This allows it to integrate with compatible IP surveillance systems, network video recorders and security management platforms.

Its fixed dome design provides a compact installation option, while IP67 protection helps protect against water and dust. IK10 vandal resistance adds physical protection for installations where the camera may be exposed to impact or tampering.
