Dahua Technology WizSense IPC-HDBW2841R-ZAS-27135-B security camera Dome IP security camera Indoor & outdoor 3840 x 2160 pixels Ceiling/wall

The Dahua Technology IPC-HDBW2841R-ZAS-27135-B is an IP security camera offering 8 MP (3840 × 2160) resolution with a 1/2.7" CMOS sensor and a 2.7–13.5 mm motorized lens. Designed for indoor and outdoor installation, the dome camera supports PoE or 12 VDC power, has built-in IR LEDs for night vision up to 40 m, and meets IP67 and IK10 protection ratings. It includes on-board storage support (microSD up to 256 GB), one-way audio with built‑in microphone, and wired Ethernet connectivity.

Advantages

This model uses Dahua’s WizSense AI engine to provide human and vehicle detection with high accuracy, reducing false alarms and enabling faster target search. It supports H.265/H.264 codecs with smart compression (SMART H.264+/H.265+ and ROI) to lower bandwidth and storage needs. Robust construction (IP67, IK10), PoE power option and flexible mounting (ceiling or wall) make installation and long-term outdoor use practical.

Suitable for

• Perimeter and property surveillance (outdoor)
• Entrances, lobbies and corridors (indoor)
• Parking lots and driveways with vehicle detection
• Retail and small-business security with event-based alerts

How to use

Mount the dome camera on a suitable ceiling or wall bracket and connect to power via PoE or a 12 VDC supply. Connect the camera to a network switch or NVR using a wired Ethernet cable. Configure basic settings through Dahua’s configuration tools or a compatible NVR: set resolution and frame rate, enable AI functions (human/vehicle detection and SMD), and configure recording schedules and alarm actions. Insert a microSD card to enable local recording if required. Verify night performance and adjust IR and exposure settings as needed for the monitored scene.

Recommendations

Place the camera at a height and angle that provide unobstructed views of important approaches; for reliable human and vehicle detection enable SMD Plus and adjust sensitivity to reduce false alarms. Use PoE for simpler cabling and ensure firmware is kept up to date for best AI performance and security.
