Dahua 8MP Starlight DH-HAC-HFW2802T-Z-A-DP HDCVI Bullet Camera with 3.7–11mm Motorised Lens, 80m IR

Product SKU: DH-HAC-HFW2802T-Z-A-DP

Product Overview

The Dahua DH-HAC-HFW2802T-Z-A-DP iVI bullet camera designed for detailed surveillance across driveways, building perimeters, warehouses, loading areas and larger outdoor access points. Its adjustable 3.7–11mm motorised lens gives installers greater control over the final field of view, allowing the same camera to cover a broad scene or concentrate detail on a more distant target. The camera combines 4K image output, low-light Starlight performance, 120dB True WDR and Smart IR illumination reaching up to 80 metres. A built-in microphone supports audio capture, while the IP67 aluminium housing is suited to exposed outdoor installations. This model is particularly useful when upgrading or extending a coax-based HDCVI system where adjustable coverage, long-range infrared and higher-resolution recording are more important than PoE connectivity or full-colour white-light night vision.

Key Capabilities

Best For

• Driveways and Entry Gates: Adjust the lens for a wide vehicle approach or a tighter view of the gate and entry point.
• Warehouses and Loading Areas: The 8MP output, long-range infrared and bullet-style housing suit larger external operational areas.
• Building Perimeters: Use the narrower lens setting to monitor fence lines, side access paths or extended boundary sections.
• Existing Coax CCTV Upgrades: Suitable for compatible HDCVI systems where existing BNC cabling is being retained and the recorder supports 8MP input.

Why Choose the DH-HAC-HFW2802T-Z-A-DP

The main reason to choose this model is its combination of adjustable optical coverage, 8MP recording and long-range infrared in a conventional HDCVI bullet format. A cheaper fixed-lens camera may provide adequate general coverage, but it cannot be framed as precisely when the required view changes between a wide overview and a distant entrance or boundary. The DH-HAC-HFW2802T-Z-A-DP also offers a larger 1/1.8-inch sensor, Starlight sensitivity, 120dB WDR and built-in microphone, making it better suited to challenging scenes than a basic daytime-focused coax camera. Offered through Security Wholesalers, it is a practical option for compatible 4K HDCVI upgrades where the buyer wants improved detail without converting the complete site to an IP camera system.

Ideal Use Cases

Choosing the Right Model

• Choose this model if: You need an 8MP HDCVI bullet camera with adjustable 3.7–11mm coverage, Starlight sensitivity, built-in microphone and infrared reaching up to 80 metres.
• Choose a fixed-lens model if: The required scene is already known and a lower-cost wide or narrow fixed view will provide sufficient coverage.
• Choose a full-colour night model if: Retaining colour in very dark conditions is more important than long-range infrared surveillance.
• Choose an IP camera if: The installation requires PoE network cabling, direct network connectivity or IP-specific recorder features rather than HDCVI over coax.
• Choose an active-deterrence model if: A built-in warning light, speaker, siren or two-way talk function is required at the camera position.

FAQs

1. Is the DH-HAC-HFW2802T-Z-A-DP suitable for driveways and large entrances?
   Yes. The DH-HAC-HFW2802T-Z-A-DP suits driveways and larger entrances where adjustable coverage and detailed 8MP recording are useful. Its motorised 3.7–11mm lens can be set for a broad overview or a tighter view of a gate, vehicle approach or access point. The final identification result depends on mounting height, angle, lighting and how tightly the lens is set.
2. What does the 3.7–11mm motorised lens allow me to adjust?
   The motorised lens lets the field of view be changed without replacing the lens. At the wide end, the horizontal view is approximately 112 degrees for broader coverage. At the tele end, it narrows to approximately 46 degrees to concentrate more pixels on a smaller, more distant area. This makes the camera more flexible than a fixed-lens model during commissioning and final scene adjustment.
3. How does the DH-HAC-HFW2802T-Z-A-DP perform at night?
   The camera combines Starlight sensitivity with Smart IR illumination rated to a maximum of 80 metres. Starlight helps retain usable detail in low-light scenes, while the infrared system supports monitoring when the area becomes dark. This is an IR night-vision camera rather than a full-colour white-light model, so very dark scenes will normally be captured using infrared rather than continuous colour.
4. Does this Dahua HDCVI camera record audio?
   Yes. The DH-HAC-HFW2802T-Z-A-DP includes a built-in microphone and one audio input interface. Audio recording still depends on the connected recorder, channel configuration and local privacy requirements. The camera does not list a built-in speaker, so it should not be described as a two-way-audio camera. Choose a different model when talk-back or an audible warning function is required at the camera.
5. Can the DH-HAC-HFW2802T-Z-A-DP be installed outdoors?
   Yes. The aluminium housing carries an IP67 ingress-protection rating and the specified operating range is -30°C to +60°C at less than 90% relative humidity. This makes it suitable for exposed outdoor positions when correctly installed and sealed. An impact-resistance rating is not specified, so locations exposed to deliberate tampering may require careful mounting height, protective placement or a camera with a confirmed vandal-resistant rating.
6. What recorder is required for this 8MP HDCVI camera?
   Use a recorder with BNC HDCVI inputs that explicitly supports 8MP or 4K camera input at the required frame rate. The camera outputs 4K at up to 15 frames per second, with higher frame-rate options available at lower resolutions. Before replacing an older coax camera, confirm the recorder channel supports this resolution and that the existing cable and connectors are in suitable condition.
7. Does the camera need a separate power supply?
   Yes. The camera accepts 12V DC or 24V AC power and has a maximum stated consumption of 15W with infrared operating. Plan the power source and cable route separately from the BNC video connection. For an installation supplied by Security Wholesalers, confirm whether the existing cabling includes suitable power conductors or whether a local regulated power supply will be installed near the camera.
8. How far away can the camera recognise or identify a subject?
   The published DORI guidance varies with the lens position. At the wide setting, the approximate recognise and identify distances are 17 metres and 8 metres. At the tele setting, they increase to approximately 38 metres and 19 metres. These figures are general planning references rather than guaranteed forensic results, because real performance also depends on lighting, movement, mounting angle, scene contrast and recorder settings.
