Product SKU: DH-IPC-HDBW5631RP-ZE-27135-1
Product Overview
The Dahua DH-IPC-HDBW5631RP-ZE-27135-BLK is a 6MP motorised varifocal dome camera finished in black, designed for installers and integrators who need flexible framing, high-resolution imaging, and robust construction in a single unit. Featuring a 2.7mm–13.5mm motorised lens, the camera can be remotely adjusted to suit a wide range of mounting distances and scene widths without physical lens access. The 1/2.9″ STARVIS CMOS sensor delivers sharp detail in low-light conditions, while True WDR (120dB) ensures clear footage in scenes with extreme contrast — such as entranceways with bright outdoor light. With H.265 encoding, IP67 weatherproofing, IK10 vandal resistance, PoE support, and up to 50m IR night vision, this camera suits demanding commercial and residential installations where image quality and durability are non-negotiable.
Key Capabilities
6MP STARVIS CMOS Sensor
The 1/2.9″ STARVIS progressive scan CMOS captures 6-megapixel resolution at up to 20fps, delivering crisp, detailed imagery suitable for licence plate identification, facial recognition, and wide-area surveillance where fine detail is essential.
Motorised Varifocal Lens (2.7mm–13.5mm)
The motorised 2.7mm–13.5mm lens allows remote zoom and focus adjustment via the camera’s interface, saving significant time during installation and commissioning — particularly useful when the camera is mounted at height or in a difficult-to-reach location.
True WDR (120dB)
True Wide Dynamic Range at 120dB handles high-contrast scenes — such as a lobby with bright windows and a dark interior — by balancing exposure across the full frame, ensuring faces and detail remain visible in both bright and shadowed areas simultaneously.
Smart IR up to 50m
The integrated IR illuminators provide effective night vision coverage up to 50 metres. Smart IR technology automatically adjusts IR intensity to prevent overexposure of nearby subjects, maintaining usable image quality across the full detection range throughout the night.
H.265 Efficient Encoding
H.265 dual-stream encoding reduces file sizes by up to 50% compared to H.264 at equivalent quality, lowering both storage costs and network bandwidth requirements — a practical advantage for multi-camera NVR installations with limited storage or constrained network infrastructure.
IP67 & IK10 Protection
Rated IP67 for full dust ingress protection and water immersion resistance, and IK10 for resistance to physical impact, this camera is built for exposed outdoor installations, car parks, and high-traffic areas where vandalism or harsh weather are ongoing concerns.
Best For
- Commercial Building Entrances: The True WDR and 6MP resolution make it ideal for monitoring lobbies and entry points where contrast between indoor and outdoor lighting is a constant challenge.
- Car Parks and Driveways: The 50m IR range and motorised zoom allow coverage of long driveways or open car park bays with the ability to capture vehicle detail at distance.
- Retail and Warehouse Facilities: High-resolution imaging combined with IVS and face detection analytics supports loss prevention and access monitoring in retail or storage environments.
- Outdoor Perimeter Surveillance: The IP67 and IK10 ratings ensure reliable operation in exposed outdoor conditions, including rain, dust, and potential physical interference.
- Installations Requiring Discreet Appearance: The black housing makes this camera suitable for locations where a dark or low-visibility finish is preferred over the standard white variant.
Why Choose the DH-IPC-HDBW5631RP-ZE-27135-BLK
Compared to a standard fixed-lens dome camera, the DH-IPC-HDBW5631RP-ZE-27135-BLK offers significantly more flexibility and future-proofing. The motorised varifocal lens eliminates the guesswork of fixed focal length selection during planning, and allows on-site fine-tuning after mounting without physically accessing the lens housing. The 6MP resolution provides more than double the detail of a 1080p camera, which is particularly valuable when footage needs to be reviewed for identification purposes. The combination of True WDR, STARVIS low-light performance, smart IR, and intelligent analytics like IVS and face detection puts this camera in a performance bracket well above entry-level IP options. Available through Security Wholesalers, this model also supports PoE and Micro SD local storage, giving installers straightforward deployment options with built-in redundancy.

Buyer Decision Tips
Buyer Tip: If your installation site has high-contrast lighting conditions — such as a glass-fronted entrance, covered car park, or area with mixed artificial and natural light — prioritise the True WDR capability of this camera over lower-cost alternatives that only offer digital WDR, which cannot achieve the same level of detail retention in extreme contrast scenes.
Buyer Tip: This camera is listed as the black variant. If your project requires a standard white finish to match existing infrastructure or comply with aesthetic guidelines, refer to the white version of this camera (DH-IPC-HDBW5631RP-ZE-27135) linked in the product page.

FAQs
- What is the difference between this black model and the white version?
The DH-IPC-HDBW5631RP-ZE-27135-BLK is the black housing variant of the DH-IPC-HDBW5631RP-ZE-27135. Both cameras share the same core specifications — 6MP resolution, motorised 2.7mm–13.5mm lens, True WDR, 50m IR, and IK10/IP67 ratings. The only difference is the external housing colour. The white version is linked directly from this product’s page for easy comparison. - Does this camera support Power over Ethernet (PoE)?
Yes, this camera supports standard PoE, with ePOE also available as an optional configuration. PoE simplifies cabling by delivering both data and power over a single Cat5e or Cat6 cable, reducing installation complexity and cost — particularly useful when running cabling to remote or elevated mounting positions. - What does True WDR mean, and why does it matter at 120dB?
True WDR (Wide Dynamic Range) uses hardware-level dual exposure to capture detail in both very bright and very dark areas of the same scene simultaneously. At 120dB, this camera handles extreme contrast ratios — such as a person standing in a doorway with bright sunlight behind them — far more effectively than cameras that rely only on digital WDR processing techniques. - Can the motorised lens be adjusted remotely after installation?
Yes. The 2.7mm–13.5mm motorised varifocal lens can be adjusted for zoom and focus remotely through the camera’s web interface or via compatible CMS software such as DSS or PSS. This means installers can fine-tune the field of view after the camera is physically mounted, without needing to access the camera housing again. - What analytics does this camera support?
This camera supports IVS (Intelligent Video System) and Face Detection. IVS includes functions such as tripwire detection and intrusion detection, enabling the camera to trigger alerts when defined rules are breached. These analytics are processed on-camera, reducing the processing load on connected NVRs or servers. - Is local storage supported, and how does it work?
Yes, the camera includes a Micro SD card slot for local on-camera storage. This allows footage to be recorded directly to the card, which is useful as a backup in the event of network failure or NVR disconnection, providing an additional layer of recording redundancy without requiring additional hardware. - What mounting accessories are compatible with this camera?
Dahua lists 2 optional accessories confirmed for this model: the PFA137 junction box and the PFB203W wall mount bracket. These accessories are designed specifically for this camera family and ensure a clean, secure installation on wall or ceiling surfaces. Check availability with your supplier when ordering. - Where can I purchase the DH-IPC-HDBW5631RP-ZE-27135-BLK in Australia?
