Overview:

The Hikvision DS-2CD2046G2H-IU is a 4 MP Powered by DarkFighter fixed mini bullet network camera designed for reliable security monitoring in residential, commercial and industrial environments. With a 2.8mm fixed lens and 2688 x 1520 maximum resolution, it delivers detailed video while maintaining strong image quality in challenging lighting conditions. Powered by DarkFighter technology, the camera is designed to provide improved low-light performance, while 120 dB true WDR helps maintain clear images where bright and dark areas appear together.

Description:

The Hikvision DS-2CD2046G2H-IU combines high-resolution imaging, intelligent video analysis and efficient network connectivity in a compact bullet camera. Its 4 MP sensor provides detailed surveillance footage, while H.265+ compression helps reduce bandwidth and storage requirements without sacrificing practical image quality.

Built-in audio capability adds another layer of monitoring, with an integrated microphone supporting real-time audio capture. The camera also provides intelligent detection capabilities, including human and vehicle target classification, face capture and perimeter protection. With IP67 water and dust resistance, it is suitable for outdoor installations where the camera may be exposed to changing weather conditions.

Features:

Clear Imaging in Difficult Lighting
DarkFighter technology helps the camera produce usable images in low-light environments, making it suitable for monitoring areas that are not consistently well illuminated. When scenes contain strong backlighting, 120 dB true WDR helps balance bright and dark areas so important details remain visible.

Additional image processing includes BLC, HLC and 3D DNR, providing further assistance when dealing with difficult lighting conditions and image noise.

Smart Security Monitoring
The camera uses deep learning based analysis to distinguish between human and vehicle targets, helping reduce unnecessary alerts compared with basic motion detection. It also supports face capture and perimeter protection for installations where more advanced security monitoring is required.

Key intelligent monitoring functions include:

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

Video and Network Performance
The DS-2CD2046G2H-IU supports H.265, H.264, H.265+ and H.264+ video compression. H.265+ is particularly useful for reducing network traffic and storage requirements when the camera is recording continuously.

Video and connectivity details include:

• 4 MP image resolution
• Maximum resolution of 2688 x 1520
• Up to 25 fps at 2688 x 1520
• 2.8mm fixed lens
• H.265, H.264, H.265+ and H.264+ compression
• 1 x RJ45 10/100M self-adaptive Ethernet port
• Built-in memory card slot
• Mono sound support

Built for Outdoor Installation
With an IP67-rated enclosure, this Hikvision mini bullet camera is designed to resist water and dust, making it suitable for outdoor security applications. Its compact fixed bullet design can be used around buildings, entrances, driveways, walkways, commercial premises and other areas requiring dependable network video surveillance.

The built-in microphone provides audio monitoring in supported installations, while the memory card slot offers a convenient local storage option alongside network-based recording solutions.

Hikvision DS-2CD2046G2H-IU Applications
This 4 MP network camera is well suited to homes, offices, warehouses, retail stores, commercial buildings, industrial sites, entrances and outdoor perimeter areas. Its combination of DarkFighter low-light imaging, WDR, intelligent target classification and IP67 protection makes it a versatile choice for day and night surveillance.
