Product SKU: DH-IPC-HDBW5631RP-ZE-27135
Product Overview
The Dahua IPC-HDBW5631RP-ZE-27135 is a 6MP vandal-resistant motorised dome network camera designed for installations requiring flexible optical zoom and high-resolution detail in challenging lighting conditions. Featuring a 2.7mm–13.5mm motorised varifocal lens, installers can remotely adjust the field of view without physical access to the camera, saving considerable time on site. Built on a 1/2.9″ Sony STARVIS CMOS sensor with Starlight low-light technology and 50m smart IR, it captures clear footage around the clock. True WDR at 120dB handles scenes with extreme contrast such as entry points and carparks. H.265 dual-stream encoding keeps storage and bandwidth demands low, while IP67 weatherproofing and IK10 vandal resistance make it suited to exposed or high-risk locations. Please note this model is End of Life — a WizSense replacement is available.
Key Capabilities
6MP STARVIS CMOS Sensor
The 1/2.9″ Sony STARVIS progressive scan sensor delivers 6-megapixel resolution at up to 20fps, providing fine detail for facial and licence plate identification — critical in commercial and retail security applications where evidentiary image quality matters.
Motorised Varifocal Lens (2.7–13.5mm)
The motorised 2.7mm–13.5mm lens allows remote optical zoom adjustment without physically repositioning or accessing the camera. This dramatically reduces installation time and is especially valuable when cameras are mounted at height or in difficult-to-reach locations.
True WDR at 120dB
True Wide Dynamic Range at 120dB prevents overexposure and detail loss in high-contrast scenes — such as doorways with bright sunlight behind subjects. Both shadow and highlight areas remain clearly visible in a single frame, improving identification accuracy.
50m Smart IR Night Vision
Smart IR LEDs illuminate up to 50 metres in complete darkness while automatically adjusting intensity to prevent overexposure of nearby subjects. This ensures consistent image quality whether a subject is close to the camera or at the far end of the IR range.
H.265 Efficient Encoding
H.265 dual-stream encoding significantly reduces file sizes compared to H.264, cutting storage requirements and network bandwidth consumption without sacrificing image quality. This allows more cameras to be supported on existing infrastructure and extends NVR storage capacity.
IP67 & IK10 Protection
Fully sealed to IP67 against dust and water ingress, and rated IK10 for vandal resistance, this camera withstands harsh outdoor environments and deliberate physical attack. It is suitable for exposed locations including building exteriors, car parks, and public-facing installations.
Best For
- Commercial Entrances: True WDR and 6MP resolution make it effective at capturing faces and vehicle details at building entry and exit points regardless of backlight conditions.
- Car Parks & Outdoor Areas: IP67 weatherproofing and IK10 vandal resistance ensure reliable operation in exposed outdoor environments subject to weather and physical interference.
- Retail Premises: High-resolution footage supports post-incident review and can deter theft in environments where detailed identification imagery is required.
- Installations Requiring Remote Lens Adjustment: The motorised varifocal lens is ideal where cameras are mounted at height or in positions where physical access for lens adjustment is impractical after installation.
- Bandwidth-Constrained Networks: H.265 encoding reduces the network load, making this camera a practical choice where multiple cameras must share limited network infrastructure.
Why Choose the DH-IPC-HDBW5631RP-ZE-27135
Compared to a standard fixed-lens 2MP dome camera, this model offers substantially greater image detail at 6MP, a motorised zoom lens for flexible coverage without physical adjustment, and Starlight technology for low-light performance that basic cameras cannot match. The 120dB True WDR capability means it handles real-world lighting challenges — such as sunlit entrances — that simpler cameras struggle with, often producing washed-out or silhouetted images. The H.265 encoding reduces ongoing infrastructure costs by cutting storage and bandwidth usage. IK10 vandal resistance adds a layer of physical protection that standard cameras lack, making it worthwhile in higher-risk locations. Security Wholesalers stocks this model for trade buyers who need proven performance in demanding commercial environments. Note that this model is End of Life, and a current WizSense replacement is available for new deployments.
Buyer Decision Tips
Buyer Tip: This model is confirmed End of Life. If you are planning a new installation rather than a like-for-like replacement, consider the WizSense replacement model listed in the product description, which offers updated features and ongoing firmware support from Dahua.
Buyer Tip: This camera supports PoE for single-cable installation. Confirm your NVR or PoE switch supports the required power output before purchasing. An optional junction box (PFA137) and wall mount (PFB203W) are available as accessories if required for your installation type.

Ideal Use Cases
Building Entrances & Lobbies
True WDR at 120dB and 6MP resolution provide clear facial detail at entry points where backlit conditions and high foot traffic create challenging imaging scenarios.
Outdoor Car Parks
IP67 and IK10 ratings protect the camera in exposed outdoor environments, while 50m IR ensures licence plates and vehicles are captured clearly after dark.
Retail Stores
High-resolution footage supports loss prevention and post-incident review, with intelligent features including face detection assisting in identifying persons of interest.
Perimeter Monitoring
The motorised zoom lens allows coverage to be precisely tuned to perimeter boundaries, and IVS analytics can trigger alerts on line crossing or intrusion detection events.

FAQs
- What does the motorised lens on this camera do?
The 2.7mm–13.5mm motorised varifocal lens allows the zoom and focus to be adjusted remotely via software rather than manually at the camera. This is particularly useful when cameras are installed at height or in locations that are difficult to access physically, saving time and reducing the need for additional site visits during commissioning. - Is this camera suitable for outdoor installation?
Yes. The DH-IPC-HDBW5631RP-ZE-27135 is rated IP67, meaning it is fully protected against dust ingress and water immersion. Combined with IK10 vandal resistance, it is suitable for exposed outdoor environments including building exteriors, car parks, and public-facing locations. - What is True WDR and why does it matter?
True Wide Dynamic Range (WDR) at 120dB allows the camera to simultaneously capture detail in very bright and very dark areas of the same frame. This is essential at entry points, gates, or shopfronts where natural light behind a subject would otherwise create a silhouette effect, obscuring facial detail. - This model is listed as End of Life — should I still buy it?
If you require a like-for-like replacement for an existing system using this exact model, purchasing available stock may be appropriate. For new installations, the WizSense replacement model referenced in the product listing offers updated features and continued manufacturer support and is the recommended choice going forward. - Does this camera support Power over Ethernet?
Yes, the DH-IPC-HDBW5631RP-ZE-27135 supports ePOE, allowing it to receive both power and data over a single Ethernet cable. This simplifies cabling runs and reduces installation costs. Ensure your PoE switch or NVR provides sufficient power output for the camera’s requirements of less than 8.5W. - Can this camera store footage locally?
Yes, the camera includes a Micro SD card slot for local on-board storage. This provides a backup recording option independent of a network recorder, which can be useful in the event of network disruption or as a supplementary storage solution. - What intelligent features does this camera include?
The camera supports Face Detection and IVS (Intelligent Video Surveillance), which includes functions such as tripwire and intrusion detection. These features allow the system to generate alerts based on specific behaviours rather than relying solely on motion detection, reducing false alarms in busy environments. - Where can I purchase this camera and is stock available?
Security Wholesalers carries Dahua IP cameras for trade buyers across Australia. Because this model is End of Life, stock availability may be limited. Contact the team directly to confirm current availability or to discuss the recommended WizSense replacement option.
