Key Capabilities
6MP STARVIS CMOS Sensor
The 1/2.9″ Sony STARVIS CMOS delivers 6-megapixel resolution at up to 20fps, producing detailed footage that makes it easier to identify faces, licence plates, and activity across wide scenes — even in challenging lighting environments.
Motorised Varifocal Lens (2.7–13.5mm)
The motorised 2.7–13.5mm lens allows remote optical zoom and autofocus adjustment via the NVR or web interface, eliminating the need to physically reposition or climb to the camera during setup or when coverage requirements change.
50m Smart IR Night Vision
Intelligent IR illumination reaches up to 50 metres and automatically adjusts intensity based on scene distance, preventing overexposure of nearby subjects while maintaining clarity at the edge of the IR range throughout the night.
H.265 Dual-Stream Encoding
H.265 compression reduces file sizes by up to 50% compared with H.264 at equivalent quality, lowering both storage requirements and network bandwidth consumption — a significant advantage for multi-camera deployments running continuous recording.
IP67 Weatherproofing & IK10 Vandal Resistance
Fully sealed against dust ingress and capable of withstanding powerful water jets, the IP67 rating ensures reliable outdoor operation. The IK10 impact rating protects against deliberate physical tampering, making it suitable for exposed or publicly accessible locations.
PoE & Micro SD Local Storage
Power over Ethernet simplifies installation by delivering both power and data through a single cable, reducing cabling costs and complexity. Onboard Micro SD support provides local recording redundancy if the network connection to the NVR is interrupted.
Best For
- Commercial Perimeters: The 50m IR range and motorised varifocal lens make this camera well suited to monitoring building entrances, fence lines, and external corridors where coverage distances vary.
- Carparks & Loading Docks: 6MP resolution provides the detail needed to capture licence plates and vehicle movement across wide open areas, particularly useful when paired with WDR for high-contrast lighting conditions.
- Warehouses & Industrial Sites: IK10 vandal resistance and IP67 weatherproofing make this camera a practical choice for dusty, wet, or physically demanding environments common in industrial settings.
- Retail & Mixed-Use Buildings: The motorised lens allows installers to fine-tune the field of view to match irregular floor plans or specific monitoring zones without physical camera adjustment after mounting.
- Installations Requiring Local Recording Backup: Onboard Micro SD support suits deployments where network reliability cannot be guaranteed and local footage redundancy is a priority.
Why Choose the DH-IPC-HFW5631EP-ZE-27135
Fixed-lens bullet cameras may cover general areas adequately, but they lock installers into a single field of view from the moment of mounting. The DH-IPC-HFW5631EP-ZE-27135 removes that constraint with its motorised 2.7–13.5mm varifocal lens, allowing precise remote adjustment of zoom and focus after installation is complete. Combined with 6MP resolution, the camera captures significantly more scene detail than standard 2MP or 4MP alternatives, giving operators more usable footage for identification purposes. H.265 encoding offsets the larger file sizes expected from higher resolution, keeping storage costs manageable. The STARVIS low-light sensor, 50m smart IR, and WDR processing ensure consistent image quality across day, night, and backlit conditions. Customers purchasing through Security Wholesalers can be confident they are receiving a genuine Dahua product backed by Australian support, with the specifications matching what is advertised.
Buyer Decision Tips
Buyer Tip: If your installation requires cameras to be mounted at heights where physical lens adjustment is impractical — such as on rooflines, high walls, or elevated brackets — the motorised varifocal lens on this camera is a significant time saver. You can dial in the exact zoom and focus remotely from an NVR or web browser after the camera is physically secured, avoiding the need for a second visit with a ladder.
Buyer Tip: This camera records at 20fps at full 6MP resolution or up to 25/30fps when set to 4MP mode. If smooth motion capture for fast-moving subjects is a priority, consider whether running the camera in 4MP mode at the higher frame rate better suits your application than the maximum resolution setting.

Ideal Use Cases
Building Perimeter Monitoring
The 50m IR range and motorised varifocal lens make this camera effective for covering external walls, fences, and entry points where lighting is limited and the required field of view may change over time.
Carpark Surveillance
6MP resolution combined with WDR processing supports licence plate capture and vehicle identification across open carpark areas where lighting transitions between bright daylight and artificial night lighting are common.
Warehouse & Logistics Facilities
IK10 vandal resistance and IP67 sealing make this camera suitable for dusty, humid, or high-traffic warehouse environments where cameras may be subject to accidental impact or harsh conditions.
Retail Premises
The motorised varifocal lens allows retailers to configure precise coverage zones — such as point-of-sale areas or stock rooms — from a single camera position without physical repositioning after mounting.
Elevated or Hard-to-Access Mounting Locations
Remote zoom and focus control via the motorised lens is particularly valuable where cameras are installed at height on rooflines or elevated brackets, removing the need for repeated physical access during commissioning.
Choosing the Right Model
- Choose this model if: You need 6MP resolution with a motorised varifocal lens for remote focus and zoom adjustment, particularly in outdoor or vandal-prone environments requiring IP67 and IK10 protection with 50m IR night vision.
- Choose a different model if: Your application requires higher resolution than 6MP, a wider IR range beyond 50m, or if budget constraints make a lower-resolution fixed-lens camera more appropriate for the coverage area.
FAQs
- What does the motorised varifocal lens do differently compared to a standard varifocal lens?
