Product SKU: DH-HAC-HFW2501CMP-A-0280B-S2
Product Overview
The Dahua DH-HAC-HFW2501CMP-A-0280B-S2 is a 5MP Starlight HDCVI bullet camera designed for homes, retail sites, offices, warehouses and commercial properties using compatible coaxial CCTV infrastructure. Its 1/2.7-inch CMOS sensor outputs widescreen 2880 × 1620 video at up to 25fps, while the fixed 2.8mm lens provides a wide 111° horizontal view for entrances, driveways and general area coverage. Starlight sensitivity, 120dB true WDR, Super Adapt and 3D noise reduction help preserve useful detail across dim and strongly backlit scenes. Three Smart IR illuminators provide a listed night range of up to 30 metres, and the built-in microphone adds supplementary audio through a compatible HDCVI recorder. The cable-mounted DIP switch allows the BNC output to change between CVI, TVI, AHD and CVBS. Its metal IP67 housing supports indoor or outdoor installation, but a compatible XVR and separate 12V DC power supply are required.
Key Capabilities
5MP 16:9 HDCVI Video
The camera outputs 2880 × 1620 video at up to 25fps through HDCVI. Its widescreen format provides detailed coverage without the unusually tall image shape associated with some older 5MP analogue formats.
Wide 2.8mm Fixed Lens
The 2.8mm lens provides an approximately 111° horizontal view, making it useful for broad entrances, driveways, shopfronts and work areas where general coverage matters more than distant magnification.
Starlight Low-Light Imaging
The F1.6 lens and Starlight sensor provide a listed minimum colour illumination of 0.001 lux. This helps retain useful colour and target detail in dim environments before the camera changes to infrared-assisted monochrome operation.
30m Smart IR
Three infrared illuminators provide a listed range of up to 30 metres. Smart IR adjusts illumination intensity as subjects move through the scene, helping reduce excessive brightness on nearby faces and reflective objects.
Built-In Microphone
The integrated microphone captures supplementary audio and transmits it through a compatible HDCVI system. This adds useful context to recorded events without installing a separate microphone at the camera position.
Four-Format Video Output
The cable-mounted DIP switch allows the BNC output to change between CVI, TVI, AHD and CVBS. This supports selected recorder upgrades, testing and mixed-format coaxial installations.
Best For
- Home Driveways and Entrances: Provides wide 5MP coverage with Starlight imaging, built-in audio and 30m Smart IR.
- Retail Shopfronts: Captures detailed video and supplementary sound around customer entrances and after-hours areas.
- Warehouses and Workshops: Suits roller doors, loading areas, storage zones and external building approaches.
- Offices and Clinics: Uses true WDR to manage entrances affected by windows, shadows and strong exterior light.
- Coaxial CCTV Upgrades: Adds 5MP video and audio while retaining suitable existing cabling and a compatible XVR.
Why Choose the DH-HAC-HFW2501CMP-A-0280B-S2
The DH-HAC-HFW2501CMP-A-0280B-S2 offers a practical upgrade for buyers who want detailed 5MP video without replacing a suitable coaxial cabling system with IP infrastructure. Its 25fps widescreen output, Starlight sensitivity and 120dB true WDR make it better suited to entrances and mixed-light scenes than a basic infrared analogue camera. The built-in microphone adds supplementary audio evidence, while the wide 2.8mm lens covers more of a driveway, room or shopfront from one position. Available through Security Wholesalers, this model is best paired with an XVR that supports 5MP 16:9 HDCVI and audio over coax. Buyers should note that the lens is fixed, the infrared range is 30 metres and the camera requires a separate 12V DC supply.
Buyer Decision Tips
Recorder Compatibility Tip: Confirm that the XVR supports 5MP 16:9 HDCVI at 25fps and built-in-microphone audio. Compatible XVR firmware should be V4.001.0000001.0.R.200908 or later for this 5MP format.
Lens and Power Tip: The wide 2.8mm lens is suited to broad coverage rather than distant identification, and it cannot be adjusted after installation. The camera uses 12V DC and does not have confirmed PoC support.

Choosing the Right Model
- Choose this model if: The site needs wide 5MP HDCVI coverage, Starlight imaging, a built-in microphone and 30m Smart IR.
- Choose a narrower lens if: More pixels are required on a distant gate, counter or identification point.
- Choose a varifocal camera if: The final field of view cannot be confirmed before installation.
- Choose an IP camera if: The project requires direct network connectivity, onboard storage or camera-side analytics.
- Confirm the recorder first if: 5MP at 25fps, built-in-microphone audio or a specific output format is required.
FAQs
- Does the DH-HAC-HFW2501CMP-A-0280B-S2 record 5MP video at 25fps?
Yes. The PAL DH-HAC-HFW2501CMP-A-0280B-S2 outputs 2880 × 1620 HDCVI video at up to 25fps. It also supports 4MP and 1080p at 25fps. The connected XVR must support the camera’s 5MP 16:9 format; Dahua specifies firmware V4.001.0000001.0.R.200908 or later for compatible recorders using this format.
- What area does the 2.8mm lens cover?
The fixed 2.8mm lens provides a wide 111° horizontal, 58° vertical and 132° diagonal field of view. It suits driveways, entrances, shopfronts and broad indoor or outdoor areas where overview coverage matters more than distant magnification. Its listed DORI distances are 63.6m detect, 25.4m observe, 12.7m recognise and 6.4m identify.
- How does Starlight imaging help at night?
Starlight imaging helps the camera retain usable colour and target detail in low ambient light before switching to infrared-assisted monochrome operation. The listed minimum illumination is 0.001 lux at F1.6, with 0 lux possible when infrared is active. Final results still depend on available light, mounting position, target movement, reflective surfaces and the condition of the connected cabling.
- How far does the Smart IR illumination reach?
The camera uses three infrared illuminators with a listed maximum range of 30 metres. Smart IR adjusts infrared intensity as a subject moves closer or farther away, helping reduce overexposure on nearby faces, clothing and reflective objects. Actual usable distance varies with mounting height, target reflectivity, weather, surrounding surfaces and the amount of ambient light in the scene.
- Does the camera have a built-in microphone?
Yes. The DH-HAC-HFW2501CMP-A-0280B-S2 includes one built-in microphone channel, allowing compatible HDCVI systems to carry supplementary audio with the video signal over the coaxial connection. The XVR must support the required audio-over-coax function and be configured correctly. Audio recording should also comply with applicable privacy, workplace-surveillance and consent requirements.
- Can this camera work with CVI, TVI, AHD and CVBS recorders?
The camera provides one BNC output that can be switched between CVI, TVI, AHD and CVBS using the cable-mounted DIP switch. Full 5MP output is available through HDCVI, while AHD and TVI are listed up to 4MP and CVBS provides standard-definition video. Confirm the recorder’s supported signal format, resolution and frame rate before changing the output mode.
- Is the DH-HAC-HFW2501CMP-A-0280B-S2 suitable for outdoor installation?
Yes. The metal housing is rated IP67 and operates from -40°C to +60°C at less than 95% non-condensing humidity. Outdoor installation still requires protected cable joints, suitable fasteners and a stable mounting surface. The camera uses 12V DC power, so power connections and any exposed BNC or DC plugs should be enclosed using an appropriate weather-resistant installation method.
- What should I confirm before adding this camera to an existing coaxial system?
Confirm that the XVR supports 5MP 16:9 HDCVI at 25fps, the required firmware level, built-in-microphone audio and the selected CVI, TVI, AHD or CVBS mode. Also inspect the coaxial cable, connectors, power delivery and storage requirements. Security Wholesalers can review the recorder model and cable arrangement to identify likely compatibility issues before installation.
