HIKVISION DS-2CD1123G2-LIU (2.8mm) – 2MP Fixed Dome Network Camera

The HIKVISION DS-2CD1123G2-LIU (2.8mm) is a high-performance 2MP dome network camera designed for reliable, round-the-clock surveillance in both residential and commercial environments. Built with advanced imaging technology, strong weatherproofing, and versatile installation options, this model delivers sharp visuals, robust protection, and easy integration into modern IP-based security systems.

Crystal-Clear 2MP Imaging

Equipped with a 1/2.8″ Progressive Scan CMOS sensor, this dome camera provides Full HD resolution of 1920 × 1080 pixels. The progressive scan ensures smooth, detailed images without distortion, even when monitoring moving objects. Its 2.8mm fixed lens offers a wide-angle field of view of 115° horizontally and 60° vertically, making it ideal for covering larger areas such as building entrances, hallways, or open spaces.

Advanced Night Vision

The camera features an infrared (IR) range of up to 30 meters (98 feet), ensuring clear images even in complete darkness. Combined with its smart IR technology, the device automatically adjusts illumination intensity to avoid overexposure and maintain balanced brightness. Whether during the day or night, users benefit from continuous, high-quality monitoring.

Efficient Video Compression

To optimize storage and bandwidth usage, the DS-2CD1123G2-LIU supports advanced video compression technologies, including:

• H.265+ – maximum efficiency, reducing data storage requirements by up to 75% compared to standard H.264.
• H.264+ – enhanced storage efficiency while maintaining quality.
• H.265/H.264 – widely compatible compression standards.

With a flexible bit rate and support for both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) control, the camera ensures efficient video streaming and storage adaptability for different network conditions.

Audio Capabilities

The camera comes with optional two-way audio support, enabling real-time communication between operators and monitored environments. This feature enhances security applications by allowing direct interaction, such as warning intruders, assisting visitors, or providing immediate instructions in monitored areas.

Weatherproof and Durable Design

The IP67 rating ensures that the DS-2CD1123G2-LIU is dustproof and waterproof, making it suitable for outdoor installations. It is engineered to withstand rain, dust, and harsh environmental conditions without compromising performance.

In addition, the camera is built to operate within extreme temperatures ranging from -30°C to 60°C (-22°F to 140°F), with humidity levels up to 95% (non-condensing). This rugged design makes it a reliable solution for both indoor and outdoor use, regardless of climate.

Flexible Power Options

For convenience, the camera supports dual power input methods:

• 12 V DC ± 25% for traditional wired setups.
• Power over Ethernet (PoE, IEEE 802.3af) for simplified installation with a single cable handling both power and data.

This flexibility ensures compatibility with various network infrastructures and reduces installation complexity.

Compact and Discreet Dome Design

The camera’s compact dimensions of 108mm × 75mm (4.25″ × 2.95″) make it easy to install in discreet locations without drawing unnecessary attention. Its dome form factor also provides tamper-resistant protection, making it harder to reposition or damage. The sleek, low-profile design blends seamlessly with both indoor and outdoor architectural environments.
