Dahua DH-IPC-HDW2831TMP-AS-0280B-S2 8MP (4K) Starlight IP Turret Fixed 2.8mm

Model: DH-IPC-HDW2831TMP-AS-0280B

Who This Is For

When 4K resolution in a compact eave or soffit mount is the priority, the Dahua HDW2831TMP-AS delivers it without requiring a large housing or complex installation. Designed for residential and small commercial installs - driveways, front entries, car parks, retail shopfronts - this turret camera combines an 8MP sensor with Starlight low-light capability and a wide 105-degree horizontal field of view from its fixed 2.8mm lens. The turret form factor mounts cleanly to a flat surface and allows the eyeball head to be physically repositioned after fixing, giving installers the flexibility to fine-tune the aim without repositioning the backplate. The built-in microphone adds audio capture for sites that need it, and IP67 weather protection means it handles exposed outdoor positions. If you are specifying a multi-camera system where 4K detail and straightforward PoE wiring both matter, this model covers both requirements in one unit.

What This Camera Actually Does

Who Buys This Model

• Residential installers: Fitting cameras to driveways, front entries, and garages where a wide 105-degree horizontal FOV from the 2.8mm lens covers the full approach in a single camera position.
• Small retail operators: Monitoring shopfronts and car parks where 4K resolution is needed for after-hours incident review and the built-in microphone adds audio context without a separate device.
• Property managers: Specifying cameras for common areas such as stairwells, lobby entries, and basement car parks where Starlight performance handles mixed or low-light conditions throughout the day.
• Security integrators building PoE systems: Running single Cat5e or Cat6 cables per camera position to keep infrastructure simple, with on-camera Micro SD as a local backup up to 256GB if the NVR connection is interrupted.

Honest Assessment

The HDW2831TMP-AS does the core job of an outdoor turret well. The 8MP sensor gives you genuine 4K detail for post-incident review, Starlight handles low-light without relying entirely on IR, and the fixed 2.8mm lens gives a broad field of view that suits typical residential and light commercial positions. H.265+ compression keeps storage requirements practical at 8MP. IVS tripwire and intrusion detection add a step above basic motion alerts for sites that need more targeted notifications. The turret's physical pan, tilt, and rotation range means precise aiming is achievable during install without repositioning the base. Where this camera will not serve you: it has no built-in speaker, so two-way audio is not available. The IR range caps at 30 metres - for longer approaches or large open yards, a camera with extended IR or a varifocal lens would be more appropriate. It is also not a full-colour camera in darkness; night operation reverts to IR-illuminated monochrome. Available through Security Australia.

Before You Buy

Quick Fit Check

• Good match if: You need wide-angle 4K coverage of a driveway or car park entry and want to mount on a flat soffit or eave - the 105-degree horizontal FOV and physical 360-degree pan adjustment let you dial in the aim precisely after fixing the base.
• Good match if: Your install involves low or variable lighting such as a dim lobby, unlit side path, or covered outdoor area - the 0.009 Lux Starlight sensitivity and 30m Smart IR handle both ambient low-light and complete darkness.
• You may need a different model if: Your site has long approaches exceeding 30 metres, subject distances that require optical zoom for identification, or you need full-colour night vision without IR - in those cases a varifocal turret, a full-colour TiOC model, or a bullet camera with extended IR range would be more appropriate for your application.

Real-World Scenarios

How It Compares

• Choose this if: You need 4K resolution in a compact outdoor turret with a wide fixed field of view, Starlight low-light performance, and PoE simplicity for residential or light commercial installs.
• You may need a different model if: Your site requires full-colour night vision without IR switching, active deterrence via a built-in siren and strobe, or longer IR range beyond 30 metres - a full-colour TiOC turret or a varifocal turret with extended IR would be more appropriate for those requirements.
• Pairs well with: An 8-channel or 16-channel 4K PoE NVR with H.265+ decoding support, and a PoE switch with sufficient wattage budget if cameras are being added to an existing network rack rather than a dedicated NVR.

Common Questions

1. Does this camera support two-way audio?

   No. The HDW2831TMP-AS has a built-in microphone for audio recording but does not include a built-in speaker. Audio capture is one-directional only. If your installation requires two-way communication - such as a front door where you need to speak to visitors - you would need a camera model with both a microphone and an integrated speaker, or a separate intercom device at that position.

2. Will this camera work on a standard PoE switch, or does it need PoE+?

   Yes, a standard IEEE 802.3af PoE switch is sufficient. This camera operates within the 15.4W budget of standard PoE, so you do not need a PoE+ (IEEE 802.3at) switch or injector. It also accepts 12V DC if you are wiring to an existing DC power supply rather than using PoE infrastructure.

3. What does 0.009 Lux minimum illumination mean in a real install?

   It means the camera produces a usable image in conditions that are very nearly pitch dark. For comparison, a moonlit outdoor environment is approximately 0.01 to 0.1 Lux. At 0.009 Lux the camera is operating right at the edge of what the Starlight sensor can capture without IR assistance - in practice this extends the useful colour or detail range before the IR LEDs fully take over, which is particularly valuable in areas with residual ambient light such as street-lit driveways or illuminated building entries.

4. What is the actual identification distance at 8MP with the 2.8mm lens?

   The confirmed DORI identify distance is 7.5 metres. DORI identify means enough pixel density on a subject's face to make a positive identification. At the observe distance of 29.9 metres you can see what a person is doing; at the recognise distance of 14.9 metres you can determine distinguishing features. The detect distance of 74.7 metres tells you something is present in the scene. Planning your camera placement around the 14.9-metre recognise threshold is practical for most evidentiary purposes.

5. Does the IVS tripwire work on this camera without a separate NVR doing the processing?

   Yes. Tripwire and intrusion detection are processed onboard the camera itself. You do not need an NVR with AI processing capability to use these features - the camera's own chip handles the video analysis and generates the alert event. The NVR or VMS simply receives and logs the event. This also means edge-based alerts can trigger recording to the Micro SD card independently of NVR connectivity.

6. Will this camera work with a non-Dahua NVR?

   Yes, in most cases. The camera is ONVIF compliant, which means it will connect to any ONVIF-compatible NVR or VMS at a base stream level. Note that advanced features such as IVS event metadata, Smart H.265+ compression, and full abnormality detection alerts typically require a Dahua NVR or software that specifically supports Dahua's SDK. If you are integrating into an existing third-party system, confirm your NVR supports the specific ONVIF profile needed for the features you want to use. The range stocked by Security Australia includes compatible Dahua NVRs if you are building a matched system.

7. How much storage does this camera use at 8MP with H.265+?

   It varies with scene complexity and motion, but as a practical guide: 8MP at 15fps with H.265+ in a typical outdoor scene with moderate activity generally runs in the range of 1.5 to 3GB per hour of continuous recording. Dropping to the 2688x1520 sub-stream at 25fps will use more per hour due to the higher frame rate. Using motion-triggered recording rather than continuous will reduce total storage consumption significantly. Always size your NVR HDD with a buffer above the calculated figure to account for high-activity periods.
