Hikvision DS-2CD2743G1-IZS 4MP IR Varifocal Outdoor Dome IP Camera

The Hikvision DS-2CD2743G1-IZS is a professional-grade 4MP outdoor dome camera engineered for demanding surveillance applications. Combining a motorized 2.8–12mm varifocal lens with advanced IR night vision and robust environmental protection, this camera delivers reliable performance across 24/7 monitoring scenarios. Built on a 1/3" progressive scan CMOS sensor, it captures crisp detail at 30fps while supporting flexible deployment through PoE power and intelligent video compression technologies.

Key Features

• 4MP resolution (2688 × 1520) with 30fps frame rate for detailed, fluid video capture
• Motorized varifocal lens (2.8–12mm) enabling horizontal FOV from 104° to 29°
• IR night vision up to 30 meters with 850nm wavelength for complete darkness operation
• 120dB Wide Dynamic Range (WDR) balancing bright and dark areas in high-contrast scenes
• IP67 weatherproof and IK10 vandal-resistant construction for outdoor durability
• H.265+/H.264+ compression reducing bandwidth and storage without quality loss
• Triple-stream architecture supporting simultaneous multi-channel delivery
• Facial recognition and advanced analytics (line crossing, intrusion detection)
• PoE-powered (802.3af Class 3) with optional 12VDC terminal block supply

Technical Specifications

Imaging & Optics: The 1/3" CMOS sensor captures vibrant color down to 0.01 Lux (F1.2 with AGC) and transitions seamlessly to IR-only imaging in zero-light conditions. The motorized lens enables remote zoom and focus adjustment, while adjustable aperture settings and slow shutter capability optimize performance across variable lighting conditions. Fixed F1.6 aperture ensures consistent light gathering.

Video Compression & Streaming: Main stream supports H.265/H.264 at up to 16 Mbps with H.265+ and H.264+ profiles for efficient bandwidth management. Sub-stream and third-stream options enable flexible multi-platform delivery, with MJPEG support for legacy systems. Video bit rate spans 32 Kbps to 16 Mbps.

Network & Integration: Full ONVIF compliance (Profile S, G, T) ensures ecosystem compatibility. Additional protocols include ISAPI, SDK, and Hikvision's proprietary Ehome for seamless NVR integration. Supports up to 6 simultaneous live view channels.

Security & Storage: Comprehensive encryption includes HTTPS, TLS1.2, and 802.1X authentication. Up to 32 user accounts with role-based access control. Onboard microSD slot (up to 128GB) with ANR (Automatic Network Replenishment) ensures continuous recording even during network interruptions. NAS and FTP support extend remote storage options.

Environmental Performance: Operates reliably from -30°C to +60°C with humidity tolerance up to 95% non-condensing. Maximum power consumption of 12W (PoE) minimizes infrastructure demands.

Applications

Ideal for perimeter security, facility monitoring, retail environments, parking structures, and campus surveillance. The varifocal lens adapts to wide-area overview or targeted identification scenarios. Advanced analytics support loss-prevention and access-control workflows.
