HK-311324135 specification sheet

Overview:

The Hikvision DS-2CD2346G2H-IU is a 4 MP fixed turret network camera designed for reliable security monitoring in residential, commercial and business environments. Powered by DarkFighter technology, it delivers clear images in challenging low-light conditions, while 120 dB WDR helps maintain image detail when scenes contain strong backlighting. The 2.8 mm fixed lens provides a wide viewing angle, making the camera suitable for monitoring entrances, walkways, offices, retail areas and other general surveillance locations.

Description:

The Hikvision DS-2CD2346G2H-IU combines high-resolution video, intelligent detection and practical network connectivity in a compact turret design. Its 4 MP sensor produces detailed 2688 x 1520 resolution video, while H.265+ compression helps reduce bandwidth and storage requirements without sacrificing useful image quality.

DarkFighter technology improves performance in low-light environments, and built-in infrared illumination provides visibility up to 30 metres when additional lighting is unavailable. The camera also supports intelligent human and vehicle target classification using deep learning, helping reduce unnecessary alerts caused by other types of movement.

For audio monitoring, the -IU model includes a built-in microphone for real-time sound capture. A built-in memory card slot provides local recording capability, while the RJ45 Ethernet connection allows the camera to be integrated into a standard IP surveillance network.

Features:

Clear 4 MP Surveillance Video
With a maximum resolution of 2688 x 1520, the camera provides detailed footage for everyday security monitoring. The fixed 2.8 mm lens is suited to wider-area viewing, making it useful for monitoring rooms, entrances and other areas where a broad field of view is required.

The camera uses 120 dB Wide Dynamic Range to improve visibility in scenes with strong differences between bright and dark areas. Backlight compensation, highlight compensation and 3D digital noise reduction further assist with maintaining usable footage in difficult lighting conditions.

Low-Light and Night Monitoring
Powered by DarkFighter technology, the Hikvision camera is designed to maintain image quality in low-light conditions. When the environment becomes dark, integrated infrared illumination can provide night-time visibility at distances of up to 30 metres.

This makes the camera suitable for continuous day and night surveillance without requiring separate infrared lighting in many installations.

Intelligent Security Monitoring
Deep learning technology allows the camera to classify human and vehicle targets, helping improve the relevance of security events and reduce unwanted detections. It also supports perimeter protection, motion detection and face capture functions for applications where more advanced monitoring is required.

Key security functions include:

• Human and vehicle target classification
• Perimeter protection
• Motion detection
• Face capture
• 1 fixed region of interest (ROI)
• Up to 6 simultaneous live view channels

Efficient Network Video
The camera includes a 10M/100M self-adaptive RJ45 Ethernet port for network connectivity. It supports H.265, H.264, H.265+ and H.264+ video compression, allowing users to select an appropriate compression method for their network and recording environment.

H.265+ can help reduce network traffic and storage requirements compared with traditional compression methods, which can be particularly useful when multiple cameras are recording continuously.

Audio and Local Storage
The built-in microphone enables real-time audio monitoring alongside video surveillance. The integrated memory card slot also provides an option for local video storage, depending on the selected memory card and recording configuration.

The camera is also designed for outdoor-capable installations, with an IP67-rated enclosure offering protection against dust and water.
