Short Description

Long Description

Overview:

The Hikvision DS-2CD2146G2H-ISU is a 4MP fixed dome network camera designed to deliver clear, reliable surveillance in demanding indoor and outdoor environments. Powered by DarkFighter technology, it provides strong low-light performance, while 120 dB WDR helps maintain image detail in scenes with bright and dark areas. The 4mm lens provides a practical viewing angle for general security monitoring, with infrared illumination extending up to 30 metres for nighttime surveillance.

Description:

The Hikvision DS-2CD2146G2H-ISU combines high-resolution imaging, intelligent video analytics and robust dome-camera protection in a compact network camera. It supports efficient H.265+ video compression to reduce bandwidth and storage requirements without compromising useful image quality. Deep learning technology can help distinguish between human and vehicle targets, making it suitable for security systems that need more accurate event detection.

With a built-in microphone, audio input and output, alarm interfaces and a memory card slot supporting up to 512GB, the camera can operate as part of a flexible surveillance installation. Its IP67 weather and dust resistance and IK10 vandal resistance make it suitable for locations where the camera may be exposed to harsh environmental conditions or physical interference.

Features:

4MP Hikvision DarkFighter Imaging
The camera captures video at up to 2688 x 1520 resolution, providing more detail than standard 2MP surveillance cameras. Hikvision DarkFighter technology is designed to improve image quality in low-light conditions, helping maintain usable surveillance footage when available lighting is limited.

For scenes affected by strong sunlight, headlights or other challenging lighting conditions, 120 dB true WDR helps balance bright and dark areas within the same image. BLC, HLC and 3D DNR further assist with difficult lighting and image noise.

Night Vision and Video Recording
Built-in infrared illumination provides an IR range of up to 30 metres, allowing the camera to continue monitoring areas in darkness. Video can be encoded using H.265, H.264, H.265+ or H.264+, providing flexibility when configuring network bandwidth and recording storage.

The camera also supports ROI for the main stream and sub-stream, allowing important areas of an image to receive greater attention during encoding.

Key video capabilities include:

• Maximum resolution: 2688 x 1520
• Resolution class: 4MP
• Lens: 4mm fixed lens
• IR range: Up to 30 metres
• Compression: H.265, H.264, H.265+, H.264+
• WDR: 120 dB true WDR
• Noise reduction: 3D DNR
• ROI: 1 fixed region for main stream and sub-stream
• Simultaneous live view: Up to 6 channels

Intelligent Security Monitoring
Deep learning-based human and vehicle classification helps improve the accuracy of security events by focusing detection on relevant target types. The camera also supports motion detection, face capture and perimeter protection for installations requiring more advanced surveillance functions.

These capabilities make the camera suitable for applications where simple video recording is not enough and the surveillance system needs intelligent event monitoring.

Network, Audio and Storage
The DS-2CD2146G2H-ISU connects to a network using a 10M/100M self-adaptive RJ45 Ethernet port. A built-in memory card slot supports cards up to 512GB, providing local recording capability where supported by the surveillance configuration.

Audio and alarm connections add further integration options:

• 1 x RJ45 10M/100M self-adaptive Ethernet port
• Built-in microphone
• 1 x audio input
• 1 x audio output
• Alarm input and output
• Built-in memory card slot supporting up to 512GB

Built for Indoor and Outdoor Security
The fixed dome housing is designed for installations where durability is important. IP67 protection helps guard against dust and water ingress, while IK10 vandal resistance provides additional protection against physical impact. This makes the camera well suited to commercial premises, entrances, perimeter areas, offices, retail environments and other security-sensitive locations.

Hikvision DS-2CD2146G2H-ISU Model Details
The specified model is the DS-2CD2146G2H-ISU(4mm)(O-STD), with the 4mm fixed lens configuration. The part number / SKU for this product is HK-311324129.

Available model variants include:

• DS-2CD2146G2H-I(2.8mm)(eF)
