Description

Manufacture: Dahua | Model: DH-SD8A840-HNF-PA

 

The 4K PTZ Camera is a high-performance surveillance solution designed for superior image clarity, advanced AI capabilities, and long-range monitoring. Equipped with a 1/1.8-inch CMOS sensor and 8MP resolution, it delivers stunning 4K UHD video with exceptional low-light performance. Featuring a powerful 40x optical zoom and 16x digital zoom, this camera provides a flexible field of view ranging from 63.9° to 2.0°. With Smart IR technology and a 500m illumination distance, it ensures reliable monitoring in total darkness. The PTZ functionality offers a 360° pan range and -30° to +90° tilt with auto flip, making it ideal for wide-area surveillance. AI-powered intelligence includes face recognition, auto-tracking, and perimeter protection with tripwire, intrusion, and loitering detection. Multiple video compression formats such as Smart H.265+ and H.264 optimize storage and bandwidth usage. The camera supports up to 3 video streams and features advanced image processing with WDR (120dB), 2D/3D noise reduction, and optical defog for enhanced clarity in challenging environments. With region of interest (RoI), privacy masking, and smart motion detection, this camera is an optimal choice for security applications in critical infrastructures, smart cities, and large-scale surveillance deployments.
