Product Overview
The Dahua HDW1631EM 6MP eyeball network camera delivers sharp, high-resolution surveillance in a compact turret-style housing suitable for both indoor and outdoor installations. Equipped with a fixed 2.8mm wide-angle lens and a 1/2.9″ STARVIS CMOS sensor, it captures detailed 6-megapixel footage at up to 20fps, making it well suited to small businesses, retail environments, residential properties, and entry-level commercial deployments. The built-in infrared array extends night vision coverage up to 50 metres, while the IP67-rated weatherproof housing ensures reliable operation in harsh Australian conditions. With H.265 compression, a built-in microphone, True WDR at 120dB, and support for Power over Ethernet, this camera offers a cost-effective solution for installers and end users seeking dependable HD surveillance without complexity.
Key Capabilities
6MP High-Resolution Imaging
The 6-megapixel STARVIS CMOS sensor produces exceptionally detailed images at 3072×2048 resolution, allowing installers and operators to confidently identify faces, number plates, and fine details that lower-resolution cameras would miss.
50m Infrared Night Vision
Built-in IR LEDs provide effective night-time illumination up to 50 metres. The Day/Night ICR filter automatically switches between colour and monochrome modes, ensuring clear footage around the clock without the need for additional lighting.
True WDR (120dB)
True Wide Dynamic Range at 120dB handles challenging lighting environments — such as entrances with bright sunlight and dark interiors — by balancing exposure across the full scene so critical details remain visible in both bright and shadowed areas.
H.265 Efficient Compression
H.265 triple-stream encoding significantly reduces bandwidth consumption and storage requirements compared to H.264, making it easier and more affordable to retain longer footage archives on NVRs or local Micro SD cards without sacrificing image quality.
Built-in Microphone
The integrated microphone captures ambient audio alongside video, adding an extra layer of situational awareness. This eliminates the cost and effort of installing a separate audio device, making the camera a practical all-in-one solution for many applications.
IP67 Weatherproof & PoE Support
The IP67-rated housing protects against dust ingress and water jets, making this camera suitable for outdoor installation in Australian weather conditions. Optional Power over Ethernet support simplifies cabling by delivering both power and data over a single network cable.
Best For
- Small Business Surveillance: Ideal for retail shops, offices, and warehouses requiring reliable HD coverage at entrances, cash registers, and storage areas.
- Residential Security: Suitable for homeowners wanting a discreet, weather-resistant camera to monitor driveways, gates, or backyards with clear night vision capability.
- Entry-Level Commercial Installations: A cost-effective choice for installers building out multi-camera IP systems where budget is a consideration but image quality cannot be compromised.
- Challenging Lighting Environments: The 120dB True WDR makes it well suited to foyers, car parks, and shopfronts where mixed lighting conditions are common throughout the day.
- Audio-Required Deployments: Locations where ambient audio monitoring is needed — such as reception areas or access points — benefit from the built-in microphone without additional hardware costs.
Why Choose the DH-IPC-HDW1631EM
While basic 2MP and 4MP cameras may seem sufficient on paper, the Dahua HDW1631EM’s 6-megapixel resolution delivers substantially more detail — critical when footage is reviewed for identification or incident evidence. The combination of True WDR at 120dB and 50m IR means this camera performs well across the full range of lighting conditions encountered in real Australian environments, from bright afternoon sun to complete darkness. H.265 compression keeps storage costs manageable even at higher resolutions, and the built-in microphone removes the need for additional audio hardware. The IP67 rating ensures long-term reliability outdoors without degradation. Customers purchasing through Security Wholesalers can be confident they are receiving genuine Dahua product supported by local stock and knowledgeable technical staff, making this camera a smart investment for both DIY users and professional installers seeking proven performance at a competitive price point.
Buyer Decision Tips
Buyer Tip: The 2.8mm fixed lens provides a wide field of view, making it best suited for covering broad areas at close to medium range. If your installation requires coverage of a longer, narrower corridor or a distant focal point, consider a model with a 3.6mm or 6mm lens instead to ensure the detail you need is captured at the required distance.
Buyer Tip: This camera supports optional PoE, which simplifies installation significantly by running both power and data over a single Cat5e/Cat6 cable. If you are building a new system, pairing this camera with a PoE-capable Dahua NVR will reduce cabling costs and installation time compared to running separate power supplies to each camera location.

Choosing the Right Model
- Choose this model if: You need a cost-effective, weatherproof 6MP eyeball camera with wide-angle coverage, built-in audio, and solid night vision performance for residential or light commercial use.
- Choose a different model if: You require advanced AI analytics, higher frame rates at full resolution, motorised varifocal zoom, or features such as perimeter protection and facial recognition — consider stepping up to the Dahua WizSense or WizMind range for those capabilities.
FAQs
- What resolution does the DH-IPC-HDW1631EM record at?
This camera records at up to 6 megapixels (3072×2048) at 20 frames per second. It can also record at 4MP (2688×1520) at 25 or 30fps. The higher resolution makes it significantly easier to identify faces and read number plates compared to standard 2MP cameras. - Does this camera work without a separate power supply if I have a PoE switch or NVR?
Yes. This camera supports Power over Ethernet, meaning it can receive both power and data through a single Cat5e or Cat6 cable connected to a compatible PoE switch or PoE NVR. This simplifies installation and reduces the cost of running separate power cabling to each camera location. - Can this camera record audio as well as video?
Yes. The DH-IPC-HDW1631EM features a built-in microphone that captures ambient audio alongside the video stream. This removes the need for a separate external microphone, making it a practical choice for locations where audio recording is a requirement. - Is this camera suitable for outdoor installation in Australia?
Yes. The IP67 ingress protection rating means the camera is fully protected against dust and can withstand water jets from any direction. It is designed to cope with the demanding outdoor conditions encountered across Australia, including heat, rain, and humidity. - How far can this camera see at night?
The built-in infrared LEDs provide effective illumination up to 50 metres in complete darkness. The Day/Night ICR filter automatically switches to monochrome mode after dark to maximise light sensitivity, ensuring clear and usable footage throughout the night. - Does this camera support local storage without an NVR?
Yes. A Micro SD card slot is built into the camera, allowing footage to be recorded locally without the need for a network video recorder. This is useful for standalone deployments or as a backup recording option in addition to NVR-based storage. - Where can I find the datasheet and further technical documentation for this camera?
