Dahua SD4A425DB-HNY-R 4MP Starlight AI Low-noise PTZ Camera 25x Zoom with Smoke cover
The Dahua SD4A425DB-HNY-R is the complete solution. With 4MP resolution, 25x optical zoom and Starlight for clear images in low light, you can monitor large areas with ease while capturing small details. The smoke dome cover makes the camera extra discreet: the viewing direction cannot be read, while the low-noise motor runs whisper-quiet and smooth. Thanks to smart AI functions such as auto-tracking and perimeter protection, you get fewer false alarms and more relevant surveillance, efficient and effective.
What this camera does
This PTZ camera combines powerful optics with smart software. The 4MP 1/2.8” STARVIS CMOS sensor ensures optimal image quality, while the 25x zoom brings every detail closer without loss of sharpness. The IP66 housing guarantees reliable operation in wind and weather. With auto-tracking the camera automatically follows people or vehicles, and AI perimeter protection helps you raise the alarm immediately in the event of genuine threats. This gives you professional security that is easy to manage and particularly cost-efficient.
