Dahua WizSense Dome IP Security Camera DH-IPC-HDBW3849R-ZAS-IL-27135 — 3840×2160, 30 fps, Ceiling, Wired, White

Dahua Technology WizSense DH-IPC-HDBW3849R-ZAS-IL-27135 is an 8MP vari-focal dome IP security camera designed for indoor and outdoor ceiling installation. It uses a 1/2.7" CMOS sensor to deliver up to 3840 × 2160 (8 MP) resolution at 25/30 fps, provides built-in multi-core lighting with both IR and warm white illumination, and supports wired Ethernet connectivity. The camera is rated IP67 and IK10 for weather and impact resistance and accepts a Micro SD card up to 512 GB.

Advantages

The camera supports H.265 and enhanced H.264/H.265 profiles for reduced bandwidth and storage use while preserving image quality. Wide dynamic range (WDR), 3D noise reduction and various exposure controls improve image clarity in challenging lighting. Integrated AI-based functions include intrusion and tripwire detection with vehicle/human classification, SMD 4.0 for refined motion screening and AI SSA support. Dual lighting provides up to 50 m of IR and 50 m of warm light for night or low-light monitoring.

Suitable for

• Ceiling-mounted surveillance in commercial buildings and offices
• Outdoor perimeter monitoring for entrances, parking areas and walkways
• Retail environments requiring people and vehicle detection
• Public spaces where robust weather and vandal protection are needed

How to use

Install the dome camera on a suitable ceiling surface with appropriate mounting hardware and run a wired Ethernet connection for network access and PoE power if used. Adjust the vari-focal lens and rotation to set the desired field of view, then configure network settings and compression profiles to match available bandwidth and storage. Enable and configure AI functions such as intrusion, tripwire and SMD area settings in the device management interface, and insert a compatible microSD card if local recording is required.

Recommendations

For reliable detection and image quality, position the camera to avoid direct bright light sources in the frame, set the SMD area to cover warm-light-trigger regions if needed, and choose H.265 or SMART H.264+/H.265+ to minimize storage use. Use PoE for simplified installation and ensure firmware is kept up to date for AI and security improvements.
