Hikvision DS-2CD2047G2-LU 4MP ColorVu Audio Outdoor Bullet IP Camera

Hikvision DS-2CD2047G2-LU 4MP ColorVu Bullet Camera

The Hikvision DS-2CD2047G2-LU is a professional-grade 4MP outdoor bullet IP camera engineered for comprehensive surveillance in challenging environments. Combining ColorVu technology with intelligent lighting and advanced video processing, this camera delivers exceptional image quality 24/7, whether monitoring residential properties, commercial facilities, or critical infrastructure.

Key Features

• 4MP resolution at 2688 × 1520 with up to 30 fps (60 Hz) main stream
• ColorVu night vision with 0.0005 Lux minimum illumination (F1.0, AGC ON)
• Smart white light supplement up to 40 meters with intelligent control
• Fixed focal lens options: 2.8mm (112° FOV), 4mm (95° FOV), or 6mm (58° FOV)
• IP67 weatherproof rating for reliable outdoor performance
• Built-in microphone with multi-codec audio support (G.711, G.722.1, G.726, MP2L2, MP3, AAC-LC)
• PoE powered (802.3af, max 7.5W) for simplified installation
• Face capture and advanced event detection capabilities

Technical Specifications

The camera features a 1/1.8" progressive scan CMOS sensor with F1.0 aperture and intelligent shutter control (1/3s to 1/100,000s). Video compression includes H.265/H.264 with H.265+/H.264+ encoding for efficient bandwidth utilization. Wide Dynamic Range (WDR) technology reaches 130 dB, enabling clear imaging in mixed lighting conditions. SNR performance exceeds 52 dB for reliable low-light operation.

The DS-2CD2047G2-LU supports multiple video streams: main stream at 2688 × 1520, sub-stream, and optional third stream for flexible multi-client deployments. Pan (0-360°), tilt (0-90°), and rotate (0-360°) adjustments enable precise coverage without repositioning. DORI capabilities vary by lens—the 6mm lens achieves 115m detection, 45m observation, 23m recognition, and 11m identification distance.

Smart Surveillance Features

Motion detection with human and vehicle classification distinguishes genuine threats from environmental activity. Line crossing detection, intrusion detection, region entrance/exit detection, and scene change detection provide context-aware alerting. Configurable linkage actions include NAS/FTP uploads, surveillance center notification, recording triggers, and email alerts. The camera supports up to 32 concurrent users across three permission levels (administrator, operator, user).

Connectivity & Storage

Native support for Open Network Video Interface (PROFILE S/G/T), ISAPI, and comprehensive SDK integration enables seamless third-party system integration. Web browser access via Chrome, Firefox, and Edge (plug-in free) supports modern deployment workflows. On-board microSD storage up to 512GB with auto network replenishment (ANR) ensures continuous recording. IP address filtering, HTTPS encryption, TLS 1.1/1.2, and security audit logging protect against unauthorized access.

Applications

Ideal for parking lots, building exteriors, perimeter security, retail environments, and industrial facilities requiring colorful night vision and extended monitoring range. The combination of low light sensitivity, intelligent white light, and durable IP67 construction makes it suitable for demanding outdoor installations.

The DS-2CD2047G2-LU stands out in the 4MP outdoor segment through its ColorVu approach to nighttime imaging. Rather than relying solely on infrared, which produces monochrome imagery and struggles with reflective surfaces, this camera combines extreme low-light sensitivity (0.0005 Lux) with smart white light supplementation. This hybrid approach delivers color details at night—critical for identifying vehicle colors, clothing, and environmental context during forensic review.

The F1.0 fixed aperture and 1/1.8" sensor enable exceptional light gathering, reducing white light dependency while maintaining color saturation. The selectable lens lineup (2.8/4/6mm) provides deployment flexibility: wide angle coverage for large areas or telephoto reach for distance detail. Audio integration with environment noise filtering adds investigative value in mixed acoustic environments.

For systems integrators, the triple-stream architecture with flexible codec support (H.265+ for bandwidth optimization, H.264 for legacy compatibility) simplifies multi-camera deployments. Native ISAPI and SDK support ensure vendor lock-in mitigation. IP67 and temperature tolerance (-30 to 60°C) confirm suitability for uncontrolled exterior mounting.
