Description

The Dahua DH-SD49225DB-HC represents a significant advancement in surveillance technology, combining exceptional imaging capabilities with precision control in a durable, weather-resistant package. This sophisticated HDCVI PTZ camera incorporates a premium 1/2.8″ 2Megapixel STARVIS™ CMOS sensor, delivering outstanding image clarity and detail in both daylight and challenging low-light conditions. The camera’s 25x optical zoom capability provides remarkable operational flexibility, enabling monitoring of expansive areas while retaining the ability to capture fine details at considerable distances.

Starlight technology is a cornerstone feature of this camera, enabling exceptional performance in minimal lighting scenarios where standard surveillance cameras would produce unusable footage. This advanced low-light capability ensures the camera maintains image clarity in challenging conditions, extending effective surveillance coverage throughout varying lighting conditions without requiring supplementary illumination. The camera operates at fluid frame rates of up to 25/30 fps at full 1080P resolution, ensuring smooth video capture essential for accurate monitoring of dynamic environments.

The DH-SD49225DB-HC incorporates 120 dB true Wide Dynamic Range (WDR) technology, enabling balanced exposure in scenes with extreme brightness variations. This advanced imaging capability ensures clear visibility of both bright and shadowed areas simultaneously, addressing one of the most challenging aspects of surveillance monitoring. Complementing this, 3D Digital Noise Reduction (DNR) technology enhances image clarity by intelligently filtering visual noise, particularly beneficial in low-light conditions where noise typically degrades image quality.

For comprehensive nighttime surveillance, the camera features high-performance infrared illumination with an impressive range extending up to 100 meters. This extensive IR coverage ensures clear visibility in complete darkness, making the camera ideal for perimeter security and large-area monitoring applications where nighttime surveillance is critical. The infrared system intelligently adjusts illumination intensity based on zoom level, preventing overexposure while maintaining optimal image quality throughout the zoom range.

Engineered for reliable performance in demanding outdoor environments, the camera’s IP66-rated housing provides comprehensive protection against dust ingress and powerful water jets. This robust construction ensures dependable operation across diverse environmental conditions, from urban installations to remote monitoring locations exposed to challenging weather elements.

The camera’s motorized lens system with a focal length range of 4.8-120mm provides exceptional control over field of view and zoom capability, all remotely accessible through the management interface. With comprehensive alarm and audio input/output options, the DH-SD49225DB-HC integrates seamlessly with existing security infrastructure, enabling cohesive system operation and responsive security protocols.

Operating on 12VDC power with a maximum consumption of 22W, 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. With its combination of advanced imaging capabilities, precision control, and durable construction, the Dahua DH-SD49225DB-HC delivers a comprehensive surveillance solution for applications demanding reliability, image quality, and operational flexibility.
