Hikvision DS-2CD5546G0-IZHS 4MP Varifocal IR Outdoor Dome IP Camera
The Hikvision DS-2CD5546G0-IZHS is a professional-grade outdoor surveillance camera engineered for enterprise security deployments. Delivering 4MP resolution at 30fps, this varifocal dome combines flexible optics with robust environmental hardening to provide reliable 24/7 monitoring across diverse outdoor settings. The motorized lens (2.8–12mm or 8–32mm options) enables dynamic field-of-view adjustment without repositioning hardware, optimizing coverage for evolving security needs.
Key Features
- 4MP (2560 × 1440) resolution with 30fps main stream performance
- Motorized varifocal lens with dual mount options and P-iris control
- Integrated IR illumination up to 30m (2.8–12mm) or 50m (8–32mm) at 850nm wavelength
- 140dB wide dynamic range with advanced imaging enhancement (BLC, HLC, 3D DNR, defog, EIS)
- Pan/tilt/rotate adjustment: 0–355° pan, 0–75° tilt, 0–355° rotation
- IP67 and IK10 rated for extreme weather (-40°C to 65°C operational range with -IZHS variant)
- PoE (802.3at Class 4) and 12VDC powered with low power consumption
- Heater option for sub-zero deployments
Technical Capabilities
The camera supports five configurable video streams with H.265/H.265+, H.264/H.264+, and MJPEG compression—enabling efficient bandwidth allocation for diverse client requirements. Multi-stream architecture allows simultaneous 20-channel live viewing with granular user access controls (32 users, 3 permission tiers). Advanced analytics include motion detection, line crossing, intrusion detection, region entrance/exit, unattended baggage detection, and people counting with dynamic face tracking via ROI masking.
Network security is comprehensive: HTTPS encryption, 802.1X EAP authentication, IP filtering, watermarking, and ONVIF/ISAPI protocol support ensure compliance with enterprise IT policies. Built-in microSD slot (up to 256GB) provides local backup alongside NAS/NFS integration and automatic network recording (ANR) failover.
Smart Detection & Integration
The embedded open platform supports up to 4 custom applications, enabling integration with third-party analytics libraries. Alarm triggering supports motion, tampering, network faults, and video exceptions, with configurable FTP/HTTP/email notifications and relay output control (24VDC 1A / 110VAC 500mA).
This camera excels in applications requiring flexible zoom and precision focus without mechanical repositioning—critical for facilities monitoring large perimeters or transition zones. The 140dB WDR and low-light performance (0.002 Lux @ F1.2) ensure usable imagery across backlit scenarios and dusk-to-dawn operations. Dual lens options provide scalability: the 2.8–12mm lens suits general overview coverage, while the 8–32mm telephoto configuration addresses long-range identification tasks.
The -IZHS variant's -40°C operating floor makes it suitable for arctic/sub-arctic deployments. Network efficiency through H.265+ encoding and five-stream support reduces storage costs significantly in multi-camera installations. The integrated heater and connector-based construction minimize on-site assembly labor, while IP67/IK10 ratings and corrosion-resistant materials ensure 5+ year outdoor service life in harsh environments.
