Description

The Dahua DH-PTZ1A225-HNR-GB represents the pinnacle of advanced surveillance technology, delivering exceptional monitoring capabilities through its sophisticated WizMind Network Positioning System design. This premium 2MP PTZ camera incorporates a high-performance 1/2.8″ 2Megapixel STARVIS™ CMOS sensor that captures remarkably clear imagery even in the most challenging lighting conditions. The camera’s impressive 25x optical zoom capability provides extraordinary operational flexibility, enabling comprehensive monitoring of expansive areas while retaining the ability to capture precise details at significant distances.

Starlight technology is a cornerstone feature of this positioning system, delivering exceptional performance in minimal lighting environments where standard surveillance cameras would produce unusable footage. With an impressively low minimum illumination threshold of just 0.005 lux in color mode and 0.0005 lux in monochrome mode at F1.6, the camera maintains remarkable image clarity in near-darkness without requiring supplementary illumination. This advanced low-light performance ensures consistent surveillance effectiveness throughout varying lighting conditions, significantly extending operational capabilities.

For comprehensive nighttime monitoring, the camera incorporates high-performance infrared illumination with an extraordinary range of up to 150 meters. This exceptional IR coverage ensures clear visibility in complete darkness across substantial distances, making the positioning system ideal for perimeter security, critical infrastructure protection, and large-area surveillance applications. The intelligent IR system automatically optimizes illumination intensity based on zoom level, preventing overexposure while maintaining optimal image quality throughout the entire zoom range.

The DH-PTZ1A225-HNR-GB elevates surveillance intelligence through its comprehensive suite of WizMind 5 Series analytics, including auto-tracking, perimeter protection, face detection, and video metadata capabilities. These advanced AI-powered functions dramatically enhance detection accuracy while minimizing false alarms, transforming raw video data into actionable security intelligence. The auto-tracking feature enables autonomous subject following, maintaining surveillance continuity for moving targets without operator intervention, while metadata extraction facilitates advanced search capabilities and post-event analysis.

Engineered for reliable performance in the most demanding environments, the camera features IP67-rated construction that provides comprehensive protection against dust ingress and temporary immersion in water. This exceptional environmental protection ensures dependable operation across diverse installation scenarios, from urban deployments to remote monitoring locations exposed to severe weather elements. The robust construction maintains performance integrity in challenging conditions, delivering year-round reliability.

The camera’s precision-engineered motorized lens system with a focal length range of 4.8-120mm provides exceptional control over field of view and zoom capability. With comprehensive alarm and audio input/output options, the DH-PTZ1A225-HNR-GB integrates seamlessly with existing security infrastructure, enabling cohesive system operation and responsive security protocols. Flexible power options including PoE+ (802.3at) and 12VDC support simplify installation across various environments.

With a maximum power consumption of 24W, the camera balances performance requirements with energy efficiency considerations. The elegant white finish provides a professional appearance suitable for both discreet and visible security installations. As part of Dahua’s advanced WizMind 5 Series, this positioning system delivers enterprise-grade security features with sophisticated AI capabilities, making it an exceptional choice for organizations requiring the highest levels of surveillance intelligence and operational performance.
