Dahua Technology WizSense SD50225DB-HNY câmara de vigilância IP Bulb interior e exterior 1920 x 1080 píxeis teto

The Dahua Technology WizSense SD50225DB-HNY is an IP security PTZ camera with 1920 x 1080 resolution designed for indoor and outdoor ceiling installations. Featuring 25x optical zoom and 16x digital zoom, a horizontal viewing angle that ranges from 58.5° to 2.8°, and a minimum illumination of 0.0005 lx, the camera delivers detailed images in very low light. Built on Dahua's WizSense platform, it uses an independent AI chip and deep learning algorithms focused on detecting humans and vehicles, and combines starlight imaging, PFA focusing and wide dynamic range to provide reliable monitoring for small to medium scenes.

Advantages

The SD50225DB-HNY provides long-range visual coverage through powerful optical zoom and accurate pan/tilt control, while Starlight technology preserves color and detail in low-light conditions. PFA (Predictive Focus Algorithm) improves autofocus speed and accuracy during zooming, and WDR ensures clear footage in high-contrast lighting. Built-in IVS supports tripwire and intrusion detection, and hardware protections including IP67 rating and TVS 6000 V surge protection increase reliability in outdoor environments. Smart H.265+/H.264+ encoding reduces storage and bandwidth requirements without sacrificing image quality.

Suitable for

• Perimeter and campus surveillance
• Parking lots and large outdoor areas
• Commercial properties and warehouses
• Medium-scale public spaces requiring PTZ coverage

How to use

Mount the camera on a suitable ceiling bracket and connect it to a stable wired Ethernet network for power and data (PoE if supported by your system). Configure the camera through Dahua-compatible NVR/software or web interface, set patrol patterns and presets for pan/tilt/zoom positions, and enable IVS features such as tripwire and intrusion with appropriate detection zones. Adjust image settings (WDR, starlight mode) and encoding (Smart H.265+/H.264+) to balance image quality and storage requirements.

Recommendations

For best results, install the camera at a height and distance that match the required detection range (consider the stated detection distance up to 1655.2 m under ideal conditions), calibrate focus using PFA during initial setup, and enable Smart H.265+ to reduce storage and bandwidth. Ensure outdoor installations use proper sealing and grounding to maintain IP67 protection and surge resistance.
