Dahua DH-HAC-HDW2501TMQP-A-0280B-S2 5MP HDCVI IR Eyeball Camera (2.8mm)

Model: DH-HAC-HDW2501TMQP-A

Who This Is For

When upgrading an existing coaxial cable infrastructure without rewiring is the priority, the Dahua DH-HAC-HDW2501TMQP-A delivers 5MP resolution over legacy coax - no new cabling, no IP network required. It suits installers and property managers working on residential upgrades, small commercial premises, and mixed-use sites where an XVR-based HDCVI system is already in place or being specified fresh. The 2.8mm fixed lens gives a wide 111-degree horizontal field of view, making it well suited to eave, soffit, and wall positions covering entries, car parks, and outdoor common areas. With 60m Smart IR, Starlight low-light performance down to 0.001 Lux, and an IP67 and IK10-rated housing, this camera handles both the Australian outdoor environment and the occasional deliberate knock without complaint. The built-in microphone adds audio capture over the same coaxial run, keeping the installation tidy and the cable count low.

What This Camera Actually Does

Who Buys This Model

• Analog System Upgraders: Sites with working coaxial cable infrastructure that need a resolution jump from 1080p to 5MP without a full rewire - this is the direct upgrade path via HDCVI over existing coax.
• Residential Installers: Houses and townhouses where eave or soffit mounting needs a wide field of view, weatherproof build, and low-light performance for front entries and driveways.
• Small Business Operators: Retail stores, warehouses, and small commercial sites running an XVR-based system who want the audio capture of the built-in microphone without running separate audio cable.
• Strata and Property Managers: Apartment block common areas, car parks, and bin enclosures where the IK10 vandal rating and IP67 outdoor durability matter alongside clean aesthetics.
• Rural and Remote Installers: Properties with long cable runs, unstable mains, or lightning exposure - HDCVI's 700m coax range, ±30% voltage tolerance, and 4kV lightning protection make this a practical choice off the main grid.

Honest Assessment

The DH-HAC-HDW2501TMQP-A genuinely earns its place on coax-based upgrades. The 5MP resolution at 25fps delivers a meaningful improvement over legacy 2MP analog cameras on the same cable runs, and the Starlight sensor with 0.001 Lux sensitivity produces usable low-light footage that most similarly priced HDCVI cameras cannot match. The 60m Smart IR with automatic intensity adjustment is practical rather than a spec-sheet claim, and the combined IP67 and IK10 rating is less common at this price point. The multi-format support - HDCVI, CVBS, AHD, and TVI - makes it compatible with most XVR brands, not just Dahua recorders. Where this camera falls short: it has a built-in microphone only - there is no built-in speaker, so two-way audio is not supported. It is also a fixed 2.8mm lens, so there is no optical zoom and no ability to narrow the field of view after installation. For sites that need AI-based person and vehicle classification, active deterrence, or full-colour night vision, an IP TiOC or full-colour turret camera available through Security Australia would be the more appropriate direction.

Before You Buy

Quick Fit Check

• Good match if: You are upgrading an existing coax-cabled site to 5MP and need to retain the existing cable infrastructure - HDCVI transmission supports up to 700m over standard coaxial cable with no signal amplifier required.
• Good match if: The mounting position is an eave, soffit, or wall covering a wide entry area in low-light conditions - the 2.8mm lens, Starlight sensor, and 60m Smart IR cover this combination without compromise.
• You may need a different model if: Your site runs on an IP/PoE network infrastructure or you need AI-powered person and vehicle classification, active deterrence, or full-colour night imaging - an IP turret or TiOC camera type would be more suitable for those requirements.

Real-World Scenarios

How It Compares

• Choose this if: You are working with existing coaxial cable infrastructure and need 5MP resolution, Starlight low-light performance, and built-in audio capture without converting to an IP network.
• You may need a different model if: Your site uses a PoE switch or IP NVR infrastructure, or you need AI-based person and vehicle classification, full-colour night vision, or active deterrence - an IP turret or TiOC camera type covers those requirements.
• Pairs well with: A Dahua XVR with HDCVI and PoC support, allowing power and video to share the same coax run and eliminating the need for a separate power supply at each camera position.

Common Questions

1. Will this camera work with my existing coaxial cable and non-Dahua XVR?

   Yes, in most cases. The DH-HAC-HDW2501TMQP-A supports HDCVI, CVBS, AHD, and TVI signal formats, which are switchable via the UTC (coax control) menu. Most XVR brands that accept multi-format input will display 5MP HDCVI from this camera. The switch between formats is done through your recorder's on-screen menu rather than a physical switch on the camera body. Confirm your XVR supports 5MP HDCVI input on the channel you intend to use before purchasing.

2. Does this camera support two-way audio?

   No. This camera has a built-in microphone only - there is no built-in speaker. It captures and transmits audio from the camera location to the recorder over the coaxial cable, but cannot output audio at the camera end. If you need to speak to someone at the camera location, you would need a separate IP intercom or a camera model with both microphone and speaker built in.

3. What does the 60m IR range actually mean in practice with Smart IR?

   The 60m figure is the maximum infrared illumination distance under optimal conditions - it does not mean you will get clear identification at 60m. At the 2.8mm lens focal length, the DORI identification distance is 6.4m, recognition is 12.7m, and observation is 25.4m. Smart IR adjusts the IR LED intensity automatically as a subject moves closer to avoid overexposure - so a person approaching from 30m to 1m will remain consistently visible rather than becoming a white-out at close range.

4. How does Starlight differ from standard low-light performance on HDCVI cameras?

   Starlight achieves 0.001 Lux minimum illumination at F1.6, compared to the 0.01 to 0.1 Lux range typical of standard HDCVI cameras at this resolution. In practice, this means the sensor captures usable colour detail in scenes lit only by ambient streetlight or reflected moonlight before switching to monochrome IR mode. Standard cameras in those same conditions produce a dark, noisy image that the IR then needs to compensate for entirely.

5. Can this camera be powered over the coax cable (PoC)?

   Yes, but only if your XVR supports PoC output. The camera is PoC-compatible, which means a PoC-capable XVR can deliver DC power to the camera through the same RG59 or RG6 coaxial cable carrying the video signal, eliminating the need for a separate 12V power supply at each camera position. Not all XVR channels support PoC even on PoC-capable recorders - check your XVR's documentation for which channels have PoC output before relying on this in your installation design. The camera also accepts a standard DC12V ±30% supply if PoC is not available.

6. What is the maximum coaxial cable run for reliable 5MP video from this camera?

   700m over standard coaxial cable (RG59 or better) and 300m over UTP cable, based on Dahua lab testing. These distances apply to HDCVI signal format. If you are running CVBS in fallback mode, the distance limits will differ and resolution drops to standard definition. For runs approaching the maximum, use quality RG59 or RG6 coax with properly crimped connectors - poor terminations or cheap cable significantly reduce effective range before signal degradation appears. Security Australia stocks compatible cabling and accessories for HDCVI installations.

7. Does the IK10 rating mean this camera is fully vandal-proof?

   No, IK10 means impact resistant - not indestructible. IK10 is the highest rating on the IK scale and corresponds to resistance against a 20-joule impact, which is roughly equivalent to a 5kg object dropped from 40cm. In practice, the housing withstands firm deliberate hits from a fist or small tool without cracking open or shifting the lens position. It will not survive sustained attack with heavy implements. The rating is meaningful for deterring opportunistic tampering in public or semi-public spaces, not for high-risk hostile environments where a protected enclosure or bullet-style housing would be more appropriate.
