Hikvision DS-2CD2747G2T-LZS 4MP ColorVu AI Outdoor Dome IP Camera

Hikvision DS-2CD2747G2T-LZS 4MP ColorVu AI Dome Camera

The Hikvision DS-2CD2747G2T-LZS is a professional-grade 4MP outdoor dome IP camera engineered to deliver vivid, full-color surveillance in ultra-low-light environments. Featuring proprietary ColorVu technology with intelligent white-light supplementation up to 40 meters, this camera maintains color detail at illumination levels as low as 0.0005 Lux—making it ideal for facilities requiring 24/7 color imaging without compromise. Built-in AI capabilities enable human and vehicle detection, significantly reducing false alarms and streamlining security operations.

Key Features

• ColorVu 24/7 Technology: Continuous color imaging in darkness with 0.0005 Lux minimum illumination and intelligent white-light supplement up to 40 meters
• 4MP High Resolution: 2688 × 1520 native resolution with 25/30 fps capture for exceptional detail and identification clarity
• Motorized Varifocal Lens: 2.8–12mm zoom range with 105.4° to 56.4° horizontal FOV for flexible deployment and adaptive framing
• AI-Powered Detection: Human and vehicle classification with smart alarm triggering and face capture capabilities
• Professional-Grade Optics: F1.0 aperture, 130 dB WDR, and 52 dB SNR for superior low-light performance and dynamic range handling
• Durable Outdoor Design: IP67 weatherproofing and IK10 vandal resistance rated for harsh environmental conditions
• PoE Powered: 802.3af compliant, 12.9W max power draw for simplified installation and centralized power management

Technical Highlights

The DS-2CD2747G2T-LZS delivers exceptional long-range performance metrics: 66.8–110.4m detection range, 26.5–43.8m observation range, and 13.4–22.1m recognition range. The camera supports H.265/H.264 compression with multi-stream encoding (main, sub, and third-stream options), adaptive bitrate control (VBR/CBR), and on-board microSD storage up to 512GB with encryption and health monitoring. Advanced imaging features include 3D DNR, BLC/HLC processing, and 4-region privacy masking. Dual-stream architecture enables simultaneous 6-channel live viewing with negligible bandwidth overhead.

Network integration is comprehensive: ONVIF compliance (Profile S/G/T), ISAPI and SDK support, and multi-protocol compatibility (TCP/IP, HTTPS, RTSP, NTP, 802.1X). Built-in alarm logic supports motion detection, line crossing, intrusion, region entrance/exit, and scene change detection with customizable linkage actions including FTP/NAS upload, email notification, and relay triggering.

Applications

This camera excels in challenging surveillance scenarios: perimeter security, parking facilities, critical infrastructure sites, and environments where lighting cannot be controlled. The combination of ColorVu technology and AI detection makes it particularly valuable for loss prevention, access control verification, and evidence capture in low-light industrial and commercial installations.

The DS-2CD2747G2T-LZS represents a matured iteration of Hikvision's ColorVu platform, combining proven low-light imaging with enterprise-grade AI. The F1.0 aperture and 0.0005 Lux minimum illumination place it in the highest tier of passive low-light performers; the supplemental white-light extends practical range significantly without introducing unwanted IR reflection artifacts common in thermal-hybrid designs. The motorized varifocal lens and full-range pan/tilt adjustment (355°/75°/355°) provide mounting flexibility critical in retrofit installations.

H.265+ encoding efficiency and multi-stream support reduce bandwidth overhead in high-density deployments. IP67/IK10 ratings and -30 to +60°C operating tolerance confirm outdoor hardening. For integrators, the dual-stream architecture and ISAPI/SDK access enable custom event logic and third-party VMS embedding without firmware modification.

The 802.3af PoE compliance ensures compatibility with standard enterprise infrastructure, though power budgets in dense installations should be verified against supply ratings.
