Dahua DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 4K Starlight HDCVI IR Motorised Bullet Camera

Product SKU: DH-HAC-HFW2501TUP-Z-A-DP-27135-S2

Product Overview

The Dahua DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 is a 5MP Starlight HDCVI bullet camera designed for upgrading compatible coaxial surveillance systems without replacing established cabling. Its 2.7–13.5mm motorised vari-focal lens allows the viewing angle to be adjusted from a broad property overview to a tighter image of a gate, driveway or loading area. The camera records 2880 × 1620 video at up to 25 fps in PAL HDCVI mode and combines 120dB true WDR, 3D noise reduction and 0.001-lux colour sensitivity for challenging lighting. Four infrared illuminators provide a specified range of up to 80 metres, with Smart IR helping control close-range overexposure. A built-in microphone carries audio through compatible HDCVI equipment, while the metal IP67 enclosure supports indoor or outdoor installation. The official datasheet identifies this model as 5MP rather than 4K UHD.

Key Capabilities

Best For

• Existing Coaxial CCTV Upgrades: Adds 5MP detail, motorised framing and audio while retaining suitable BNC cabling and a compatible recorder.
• Driveways and Entry Gates: The adjustable lens can provide a wide approach view or tighter coverage of a defined vehicle or pedestrian entry point.
• Warehouses and Loading Areas: Long-range infrared, true WDR and vari-focal adjustment suit larger operational spaces with changing light.
• Building Perimeters: The visible bullet housing and IP67 construction suit exposed walls where the camera direction should be immediately apparent.
• Audio-Enabled Surveillance: The built-in microphone supports compatible installations that require sound to accompany recorded video.

Why Choose the DH-HAC-HFW2501TUP-Z-A-DP-27135-S2

The DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 is a practical choice when an existing coaxial system needs clearer video and more flexible framing without moving immediately to a full IP camera network. Its motorised lens is particularly useful where the final target distance is uncertain, allowing the installer to refine the scene after mounting. Starlight sensitivity, 120dB WDR and Smart IR support entrances that experience shadows, headlights or limited ambient lighting. The built-in microphone also adds audio evidence through a compatible HDCVI recorder. Supplied by Security Wholesalers, this model is best selected after confirming the XVR firmware, 5MP channel capability, PAL format, power source and required identification distance.

Ideal Use Cases

Choosing the Right Model

• Choose this camera if: You need 5MP HDCVI video, a remotely adjustable lens, 80m infrared, Starlight performance and a built-in microphone.
• Choose a fixed-lens camera if: The required viewing angle is already known and motorised zoom adjustment is unnecessary.
• Choose an IP camera if: The installation requires PoE networking, onboard microSD storage or network-camera analytics not specified for this HDCVI model.
• Choose a confirmed 8MP camera if: The project requires true 3840 × 2160 4K UHD rather than the verified 2880 × 1620 resolution of this model.

FAQs

1. Is the Dahua DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 a 4K camera?
   No. The supplied datasheet identifies this model as a 5MP camera with a maximum resolution of 2880 × 1620, not 3840 × 2160 4K UHD. The PAL model records 5MP video at up to 25 fps through HDCVI. Buyers specifically requiring 4K should choose a camera and recorder combination with confirmed 8MP or 3840 × 2160 support.
2. How far can the infrared night vision reach?
   The camera has four infrared illuminators with a maximum specified range of 80 metres. Smart IR adjusts illumination intensity to help reduce overexposure when a subject moves closer to the camera. Actual useful detail depends on the motorised lens position, target size, mounting angle, nearby surfaces and ambient light, so the 80-metre figure should be treated as an illumination rating rather than a guaranteed identification distance.
3. What viewing range does the 2.7–13.5mm motorised lens provide?
   The motorised vari-focal lens adjusts from a wide 113° horizontal view at 2.7mm to a tighter 31.4° view at 13.5mm. The wide setting suits broad entrances, yards and loading areas, while the telephoto setting is better for narrower lanes or more distant targets. Autofocus is supported, allowing the final scene to be refined through a compatible HDCVI recorder during commissioning.
4. Does the DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 have a built-in microphone?
   Yes. The camera includes a one-channel built-in microphone, allowing audio to be transmitted with the HDCVI video signal over compatible coaxial infrastructure. The connected XVR must support the required HDCVI audio function and channel configuration. A built-in speaker or two-way audio is not specified, so this model should be selected for audio recording rather than talkback.
5. Can this camera work with existing coaxial CCTV cabling?
   Yes. The camera is designed for HDCVI transmission over coaxial cabling and can help upgrade a compatible analogue CCTV installation without replacing every cable. Its BNC output can be switched between CVI, TVI, AHD and CVBS using the DIP switch. Maximum resolution varies by output format, and 5MP 16:9 operation requires a compatible XVR with the required firmware.
6. Is the DH-HAC-HFW2501TUP-Z-A-DP-27135-S2 suitable for outdoor installation?
   Yes. The camera has a metal housing with an IP67 protection rating and is specified to operate from −30°C to +60°C at less than 95% non-condensing humidity. Correct mounting and weatherproof cable termination remain essential. The bullet housing suits exposed walls, driveways and building perimeters where a visible directional camera and adjustable viewing angle are appropriate.
7. How is this HDCVI camera powered?
   The camera accepts either 24V AC with ±25% tolerance or 12V DC with ±10% tolerance. Maximum stated consumption is 12.5W with infrared operating. A 12V 1A adapter is listed as an optional accessory, but the power supply is not identified as a standard inclusion. Confirm the selected power source, cable voltage drop and recorder arrangement before installation.
8. What should be checked before ordering this motorised HDCVI camera?
   Confirm that the required resolution is 5MP rather than 4K, and check the compatible XVR, PAL video format, coaxial cable condition, 24V AC or 12V DC power, built-in-microphone support, lens range and 80-metre infrared suitability. For 5MP 16:9 operation, Dahua specifies XVR firmware V4.001.0000001.0.R.200908 or later. Security Wholesalers can help confirm the recorder and camera combination before purchase.
