Product SKU: DH-HAC-HDW2802TP-A
Product Overview
The Dahua DH-HAC-HDW2802TP-A is an 8MP 4K Starlight HDCVI turret camera designed for detailed surveillance across homes, shops, offices, warehouses and commercial properties. Its 1/2-inch CMOS sensor records at up to 3840 × 2160, while the 2.8mm fixed lens provides an approximately 110.8° horizontal view for broad entrances, driveways and open areas. Starlight imaging, 120dB true WDR and advanced noise reduction help retain useful detail across low-light and high-contrast scenes. Two Smart IR LEDs provide a listed infrared range of up to 50 metres, and the built-in microphone sends supplementary audio through a compatible HDCVI recording system. The aluminium housing is rated IP67 for indoor or outdoor installation. This PAL model records 4K video at up to 15fps, so buyers requiring higher frame rates should consider whether 4MP recording or a different camera model better suits fast-moving areas.
Key Capabilities
8MP 4K HDCVI Detail
The 1/2-inch CMOS sensor captures video at up to 3840 × 2160, providing significantly more image detail than standard 1080p HDCVI cameras. This supports closer review of faces, clothing, vehicles and activity across suitably positioned scenes.
Wide 2.8mm Fixed Lens
The 2.8mm lens provides an approximately 110.8° horizontal field of view. It is well suited to entrances, driveways, shopfronts and broad room coverage where a wide scene is more important than narrow long-distance magnification.
Starlight Low-Light Imaging
The large sensor and F1.6 aperture support a listed minimum colour illumination of 0.005 lux. This helps the camera retain usable colour detail in dim environments before switching to infrared-assisted monochrome operation.
50m Smart IR
Two infrared LEDs provide a listed maximum range of 50 metres. Smart IR adjusts illumination to help reduce excessive brightness when a person or object moves closer to the camera at night.
Built-In Microphone
The integrated microphone captures supplementary audio evidence and transmits it through a compatible HDCVI system. This can reduce the need for separate audio cabling when the recorder supports audio-over-coax operation.
Outdoor Aluminium Housing
The IP67-rated aluminium casing suits indoor and outdoor installations. A 12V DC input with ±30% voltage tolerance and 4kV lightning protection helps support reliable operation across challenging CCTV power and environmental conditions.
Best For
- Home Driveways and Entrances: Provides a wide 4K view of vehicles, visitors and activity near the property.
- Retail Shopfronts: Captures detailed video and supplementary audio around entrances, displays and service areas.
- Offices and Clinics: Suits reception areas, corridors and external access points requiring high-resolution evidence.
- Warehouses and Workshops: Provides broad coverage with Starlight imaging, true WDR and outdoor protection.
- Existing Coaxial CCTV Upgrades: Adds 8MP recording while retaining suitable HDCVI coaxial infrastructure.
Why Choose the DH-HAC-HDW2802TP-A
The DH-HAC-HDW2802TP-A is a practical upgrade for buyers who want 4K detail without immediately replacing an established coaxial CCTV system with IP equipment. Its large 1/2-inch sensor, Starlight performance and 120dB true WDR provide better image handling than a basic high-resolution analogue camera, particularly around entrances affected by shadows, headlights or bright backgrounds. The built-in microphone adds supplementary audio evidence through a compatible recorder, while the wide 2.8mm lens suits general property coverage. Available through Security Wholesalers, this model is best paired with an XVR that supports 8MP HDCVI input and audio-over-coax. Buyers should note that maximum 4K recording is limited to 15fps and the supplied datasheet specifies a 50-metre infrared range.
Buyer Decision Tips
Recorder Compatibility Tip: Confirm that the XVR supports 8MP HDCVI input at 15fps and audio-over-coax. An older recorder may display the camera only after its output resolution is reduced or may not record the microphone channel.
Infrared Specification Tip: The supplied datasheet for this exact non-S2 model lists Smart IR up to 50 metres. A 60-metre illumination specification applies to some later 2802 variants and should not be assumed for the DH-HAC-HDW2802TP-A covered here.

Choosing the Right Model
- Choose this model if: The site needs wide 8MP HDCVI coverage, Starlight performance, true WDR and a built-in microphone.
- Choose a narrower lens if: The priority is placing more pixels on a distant gate, counter or identification point.
- Choose a higher-frame-rate model if: Smooth capture of fast vehicles or rapidly moving subjects is more important than maximum 4K resolution.
- Choose an IP camera if: The project requires direct network connectivity, onboard storage or camera-side analytics.
- Confirm the exact variant if: A 60m infrared specification or newer S2 feature set is required.
FAQs
- Does the DH-HAC-HDW2802TP-A record in 4K?
The DH-HAC-HDW2802TP-A records at a maximum resolution of 3840 × 2160, or 8MP 4K, at up to 15 frames per second. It also supports 6MP at 20fps and 4MP at up to 25fps on the PAL model. The connected XVR must support the selected HDCVI resolution and frame rate, so recorder compatibility should be checked before upgrading an existing system.
- How far does the infrared illumination reach?
The supplied datasheet lists a maximum Smart IR distance of 50 metres using two infrared LEDs. The actual usable distance depends on target reflectivity, mounting height, weather, nearby surfaces and ambient lighting. The 60-metre figure associated with some later 2802 variants should not be assumed for this exact non-S2 model; the supplied DH-HAC-HDW2802T-A datasheet specifies up to 50 metres.
- What view does the 2.8mm lens provide?
The 2.8mm fixed lens provides a wide horizontal field of view of approximately 110.8°, making it suitable for entrances, driveways, shopfronts and broad indoor or outdoor areas. Its listed DORI distances are 84m detect, 34m observe, 17m recognise and 8m identify. These are general planning distances rather than guaranteed identification results in every installation.
- Does this camera have a built-in microphone?
Yes. The camera includes a built-in microphone and one audio-input channel. HDCVI can transmit the audio with the video signal over compatible coaxial infrastructure to a recorder that supports audio-over-coax. Audio recording should be enabled and tested during commissioning, and applicable privacy or workplace-surveillance requirements should be considered before recording sound.
- Can the camera reuse existing coaxial cable?
Yes. The camera is designed for HDCVI transmission over coaxial infrastructure and can support long cable runs when suitable cable, connectors and equipment are used. Dahua lists transmission distances of up to 700 metres for 4K and 4MP video over coaxial cable and up to 300 metres over compatible UTP arrangements. Cable condition, power loss and recorder capability should still be assessed on existing installations.
- Is the DH-HAC-HDW2802TP-A suitable for outdoor installation?
Yes. The aluminium housing is rated IP67 for protection against dust and water and operates from -30°C to +60°C at less than 90% relative humidity. Dahua notes that start-up should occur above -30°C. Correct sealing of cable joints, suitable mounting accessories and weather-protected power connections remain necessary for reliable outdoor operation.
- What power supply does this 4K HDCVI camera require?
The camera requires 12V DC and supports ±30% input-voltage tolerance. Maximum power consumption is listed as 8W with infrared illumination operating. The supplied datasheet does not state that a power adapter is included, so the power supply should be selected separately and sized for cable length, voltage drop and the total number of cameras in the system.
- What should I check before adding this camera to an existing XVR?
Confirm that the recorder supports 8MP HDCVI input at 15fps, the required lower-resolution frame rates, audio-over-coax and the camera’s selected video-output mode. Also inspect the coaxial cable, connectors, power delivery and storage requirements. When ordering through Security Wholesalers, provide the XVR model and planned cable length so the camera and recorder combination can be checked before installation.
