The Dahua IPC-HDBW2831E-S-S2 is an 8MP fixed-focal dome camera designed for sharp ultra-HD surveillance in both indoor and outdoor spaces. It combines intelligent motion detection with wide dynamic range and starlight imaging for clearer detail in difficult lighting. Built tough with IK10 and IP67 protection, it suits high-traffic or harsh environments where reliability matters.
Key Features
-
8MP Ultra-HD Clarity – Captures sharp, detailed video perfect for identifying faces and small objects.
-
Fixed 2.8 mm or 3.6 mm Lens – Wide-angle views for open spaces or narrower corridors.
-
Smart IR Night Vision (30 m) – IR LEDs auto-adjust to avoid overexposure up close.
-
Starlight Technology – Keeps color video longer in dim conditions before switching to IR.
-
AI IVS (Tripwire & Intrusion) – Helps trigger alerts only when meaningful movement is detected.
-
Smart H.265+/H.264+ Codec – Cuts bandwidth and storage use without compromising video quality.
-
MicroSD Support (up to 256 GB) – Records locally in case of network failure.
-
Weather & Vandal Resistant – Built to handle rain, dust, and tampering with IP67 and IK10 ratings.
Perfect For:
- Office building entries and lobbies
- Apartment hallways or elevators
- Small retail interiors
- Covered outdoor loading docks
- Public building interiors
- Shared spaces with light/dark transitions
Install Tips
- Choose 2.8 mm for wide indoor coverage; 3.6 mm suits more focused hallway views.
- Mount 3 m high to optimize motion and IR coverage.
- Use PoE for easy single-cable install and reduced failure points.
- Format SD card via the interface before deployment to avoid write errors.
- Ideal for covered but open-air installs (e.g. patios, entry alcoves).
- Pair with NVRs via ONVIF Profile S/G/T for broader compatibility.

Extra Info
Ultra-HD 8MP Imaging – Exceptional Clarity for Forensic-Level Detail
This camera delivers 8MP (4K) Ultra-HD resolution, providing crystal-clear video with outstanding sharpness and detail. Whether capturing facial features, license plates, or small objects at a distance, the high resolution allows for effective digital zooming during playback without losing image quality. It’s ideal for wide-area surveillance such as parking lots, corridors, or open lobbies.
Smart IR for Balanced Night Vision – Even Exposure in the Dark
Equipped with three high-performance IR LEDs, the camera provides up to 30 meters of night vision, automatically adjusting intensity to prevent overexposure of nearby subjects. This Smart IR function ensures clear, balanced nighttime images whether the subject is close to or far from the lens—making it highly effective for hallways, entryways, or perimeter walls.
Intelligent Motion with IVS – Smarter Activity Monitoring
This model supports Intelligent Video System (IVS) features such as tripwire (line-crossing) and intrusion detection, allowing the camera to detect and alert only when people or vehicles cross defined virtual zones. This helps reduce false alarms from irrelevant movement and is ideal for perimeter defense, restricted areas, and access control zones.
Smart Codec Efficiency – Compression That Saves Without Sacrificing
With support for Smart H.265+ and H.264+, the camera optimizes video file sizes based on motion intensity and scene complexity. This reduces bandwidth consumption and storage use by up to 70%, all while maintaining essential image detail—making it cost-effective for continuous recording or multi-camera installations.
Starlight Color Video – Low-Light Vision with Better Color Accuracy
Thanks to Dahua’s Starlight technology, the camera captures color video in extremely low-light conditions, preserving important visual details before needing to switch to IR mode. This provides better recognition and situational awareness during dusk, dawn, or poorly lit environments, enhancing security in parking garages, warehouses, or shaded outdoor areas.
Simple Setup with Fixed Lens – Hassle-Free Installation
Available with 2.8 mm or 3.6 mm fixed lens options, this camera is designed for quick installation without the need for post-mount lens adjustment. It’s a plug-and-mount solution that delivers consistent coverage and focus, making it perfect for volume deployments in schools, offices, or commercial buildings.
Q&A
Q: Will this record in color at night?
Yes. Thanks to Starlight tech, it stays in color longer in low-light conditions. In total darkness, it uses IR.
Q: Does this camera support audio?
No. It does not have a built-in mic or speaker.
Q: What lens should I choose — 2.8 or 3.6 mm?
2.8 mm gives a wider view, better for open areas. 3.6 mm offers tighter focus, great for hallways or gates.
Q: Can it be used outdoors?
Yes. With IP67 and IK10 ratings, it’s protected against rain, dust, and vandalism.
Q: Can I use this without an NVR?
Yes. It supports microSD (up to 256 GB), FTP/SFTP, or NAS for standalone recording.
Q: Will this work with other brands of NVR?
Yes. It supports ONVIF Profiles S, G, and T for broad compatibility.
Q: Is IR visible to the eye?
No. The IR used is invisible to human eyes but clearly lights the scene for the camera sensor.
Q: Can it be ceiling mounted?
Yes. It’s compatible with multiple mounting accessories for wall, ceiling, or pole setups.
