Hikvision DS-2CD1023G2-LIU(4mm) 2MP Smart Dual Light Bullet IP Camera with Mic

Dual Light Technology for Complete Visual Coverage

The DS-2CD1023G2-LIU features innovative dual light technology that ensures clear imaging in all scenarios:

• Infrared illumination with 30m range for traditional night vision monitoring
• Warm supplemental lighting for full-color imaging in low-light conditions
• Smart automatic switching based on environmental lighting conditions
• Intelligent light control to prevent overexposure and optimize scene illumination

Additionally, the camera incorporates a 1/2.8″ progressive scan CMOS sensor with 2 megapixel resolution, capturing detailed footage at 1920 × 1080 pixels and a smooth 30fps frame rate for fluid motion recording.

Integrated Audio Capabilities with Built-in Microphone

Unlike standard bullet cameras, the DS-2CD1023G2-LIU includes built-in audio functionality:

• Integrated omnidirectional microphone for clear audio capture
• Audio compression using G.711/G.722.1/G.726/MP2L2/PCM formats
• Configurable audio sampling rate up to 16 kHz
• Support for two-way audio when paired with compatible NVR systems

Furthermore, the audio recording capability enhances evidence collection and provides context to visual surveillance footage, making it particularly valuable for perimeter security, entrances, and outdoor applications where both visual and audio monitoring are essential.

Advanced Networking and Intelligent Features

The DS-2CD1023G2-LIU incorporates modern network technology and smart capabilities:

• H.265+ intelligent compression reducing bandwidth and storage needs by up to 80%
• Multiple network protocols including ONVIF compliance for third-party integration
• Secure remote viewing via mobile apps and web interfaces
• PoE (Power over Ethernet) support for simplified single-cable installation

Moreover, the camera includes intelligent video analytics such as line crossing detection, intrusion detection, and motion detection to provide proactive security alerts and reduce false alarms through intelligent scene analysis.

Weather-Resistant Construction for Outdoor Deployment

Engineered for reliability in challenging outdoor environments, the DS-2CD1023G2-LIU offers:

• IP67 weatherproof rating ensuring protection against dust and water immersion
• Wide operating temperature range from -30°C to 60°C (-22°F to 140°F)
• Durable metal housing for increased physical protection
• Adjustable mounting bracket for flexible positioning and coverage

In addition, the 4mm fixed lens provides an optimal 87° diagonal field of view, making it suitable for monitoring building entrances, perimeters, parking areas, and other outdoor spaces with clarity and precision.
