Dahua 5MP Starlight DH-HAC-HFW2501E-A HDCVI Bullet Camera with Built-In Mic, 2.8/3.6/6mm Lens, 40m IR

Product SKU: DH-HAC-HFW2501E-A

Product Overview

The Dahua DH-HAC-HFW2501E-A is a 5MP Starlight HDCVI bullet camera designed for detailed surveillance around homes, shops, offices, warehouses and commercial properties. Its 1/2.7-inch CMOS sensor produces a widescreen 2880 × 1620 image at up to 25fps, while selectable 2.8mm, 3.6mm and 6mm fixed-lens variants allow the viewing angle to be matched to the mounting distance. Starlight sensitivity, 120dB true WDR, Super Adapt and 3D noise reduction help retain useful detail across low-light and strongly backlit scenes. Two Smart IR illuminators provide a listed range of up to 40 metres, and the built-in microphone adds supplementary audio through a compatible recorder. The BNC output can be switched between CVI, TVI, AHD and CVBS using the cable-mounted DIP switch. Its IP67-rated housing supports demanding indoor or outdoor installations using suitable weatherproof cable protection.

Key Capabilities

Best For

• Home Driveways and Entrances: Provides detailed widescreen coverage with low-light imaging and built-in audio.
• Retail Shopfronts: Captures clear video and supplementary sound around customer entrances and after-hours areas.
• Warehouses and Workshops: Suits loading areas, roller doors, storage zones and external building approaches.
• Offices and Clinics: Uses true WDR to handle entrances affected by strong backlight, windows and changing daylight.
• Existing Coaxial CCTV Upgrades: Adds 5MP video and audio while retaining suitable coaxial infrastructure and a compatible XVR.

Why Choose the DH-HAC-HFW2501E-A

The DH-HAC-HFW2501E-A provides a useful balance of image detail, low-light performance and installation flexibility for coaxial CCTV systems. Its 5MP 16:9 output records at up to 25fps, while 120dB true WDR and Super Adapt help manage difficult entrances where shadows and bright exterior light occur in the same scene. The choice of 2.8mm, 3.6mm or 6mm lenses also allows the viewing angle to be matched more accurately than a single-lens product. Built-in audio and switchable CVI, TVI, AHD and CVBS output make it more versatile than a basic infrared bullet camera. Available through Security Wholesalers, this model is best paired with an XVR that supports 5MP HDCVI input, audio-over-coax and the selected regional frame rate.

Ideal Use Cases

Choosing the Right Model

• Choose the 2.8mm version if: The priority is broad coverage of an entrance, driveway, room or loading area.
• Choose the 3.6mm version if: A balanced general-purpose view is required without the widest lens distortion.
• Choose the 6mm version if: The subject is farther away and a narrower identification zone is more useful.
• 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, audio-over-coax or a specific TVI, AHD or CVBS mode is required.

FAQs

1. Does the DH-HAC-HFW2501E-A record 5MP video at 25fps?
   The DH-HAC-HFW2501E-A supports 5MP HDCVI output at 2880 × 1620 and up to 25 frames per second. It also supports 4MP and 1080p output, while AHD and TVI modes are listed at up to 4MP. The connected XVR must support the selected resolution, signal format and frame rate, so recorder compatibility should be confirmed before upgrading an existing coaxial system.
2. Which lens should I choose: 2.8mm, 3.6mm or 6mm?
   Choose the 2.8mm lens for the widest scene, the 3.6mm lens for a balanced general-purpose view, and the 6mm lens when the subject is farther away and a narrower view is preferred. Their listed horizontal fields of view are approximately 111°, 92° and 57° respectively. The correct choice depends on mounting distance and the area where identification detail is required.
3. How far does the infrared illumination reach?
   The camera uses two infrared illuminators with a listed maximum range of 40 metres. Smart IR helps balance infrared brightness when a person or object moves closer to the camera, reducing excessive overexposure in the centre of the image. Actual usable distance depends on the selected lens, target reflectivity, mounting height, weather, surrounding surfaces and the amount of ambient light in the scene.
4. Does the camera have a built-in microphone?
   Yes. The DH-HAC-HFW2501E-A includes one built-in microphone for capturing supplementary audio with the video. A compatible HDCVI recorder can receive the audio through the camera connection without a separate microphone at the camera position. Audio recording should be enabled and tested during commissioning, and applicable privacy, workplace-surveillance and audio-recording requirements should be considered before the microphone is used.
5. Can this camera work with TVI, AHD or older CVBS equipment?
   The camera provides one BNC output that can be switched between CVI, TVI, AHD and CVBS using the cable-mounted DIP switch. Advanced resolution and audio functions depend on the chosen format and recorder capability. CVI supports the full listed 5MP output, while TVI and AHD are listed up to 4MP and CVBS provides standard-definition video for testing or legacy compatibility.
6. Is the DH-HAC-HFW2501E-A suitable for outdoor installation?
   Yes. The camera is rated IP67 and operates from -40°C to +60°C at less than 95% non-condensing humidity. Its front cover, rear barrel and mounting bracket are metal, while the sunshield and lower decorative cover are plastic. Correct weather sealing, protected cable joints, suitable fasteners and a stable mounting surface are still required for reliable outdoor installation.
7. What power supply does this camera require?
   The DH-HAC-HFW2501E-A requires 12V DC and accepts a ±30% input-voltage tolerance. Maximum power consumption is listed as 5.9W with infrared illumination active. A power adapter is not identified as included, so the supply should be selected separately and sized for cable length, voltage drop and the total load of all cameras connected to the power distribution system.
8. What should I check before adding this camera to an existing XVR?
   Confirm that the XVR supports 5MP 16:9 HDCVI video at 25fps, audio-over-coax and the selected signal format. Also check the condition of the coaxial cable, connectors, power delivery, storage capacity and chosen lens. When ordering through Security Wholesalers, provide the recorder model and approximate mounting distance so the resolution, audio and field-of-view requirements can be checked before installation.
