Dahua HAC-HFW2501TP-Z-A-27135 Dahua 5MP Starlight Pro HDCVI IR Bullet,WDR,ICR,Motorised 2.7~13.5mm

Model: HAC-HFW2501TP-Z-A-27135

Who This Is For

When retrofitting an existing coaxial cable infrastructure is the priority, the Dahua 5MP Starlight Pro HDCVI IR Bullet with motorised 2.7-13.5mm lens is a direct upgrade path that avoids full rewiring. This camera is built for installers who need to drop a high-resolution bullet onto existing RG59 or RG6 runs and still deliver 5MP footage over distances up to 700 metres. The motorised lens covers a horizontal field of view from 102 degrees down to 29 degrees, letting you dial in the exact coverage angle after the camera is physically mounted - useful on long driveways, loading dock approaches, car parks, and perimeter fence lines where getting the lens angle right from a ladder the first time is not always practical. The built-in microphone adds audio capture over the same coaxial run, and 80-metre Smart IR handles night coverage without a separate IR illuminator.

What This Camera Actually Does

Who Buys This Model

• Analogue System Upgraders: Sites with existing coaxial cable that want 5MP resolution without the cost of full rewiring - the HDCVI format transmits over the existing RG59/RG6 runs up to 700 metres.
• Loading Dock and Warehouse Managers: Long approaches where the 2.7-13.5mm motorised lens can be narrowed down to observe vehicle details at extended distances, and 80m Smart IR covers the overnight shift.
• Car Park Operators: Entry/exit lanes with mixed lighting conditions - full sun entering and shaded interior - where 120dB WDR maintains readable footage across both zones in the same frame.
• Security Integrators on Retrofit Projects: Installers who need to adjust lens angle after mounting on a high bracket without returning to site - the motorised zoom is controlled remotely through the XVR OSD menu.
• Perimeter Fence and Boundary Monitoring: Sites needing tele-end detection coverage up to 222 metres (per DORI specification at 13.5mm) where a fixed-lens bullet would require multiple cameras for equivalent coverage.

Honest Assessment

The HAC-HFW2501TP-Z-A-27135 does several things well: the motorised lens genuinely solves a real installer problem by removing the need to physically adjust focus and zoom at height, and the combination of 0.005 lux Starlight sensitivity with 80m Smart IR means this camera performs in conditions where lower-tier HDCVI bullets fall short. The 120dB WDR rating handles high-contrast entrances and dock openings without manual scene adjustment. Transmission over existing coax at 5MP up to 700 metres is a confirmed and tested capability, not a theoretical figure. Where this camera has limits: the maximum frame rate at 5MP is 20fps, which is adequate for most fixed-position monitoring but not ideal for high-speed vehicle capture where 25/30fps is preferred. This is also an HDCVI camera, so it requires a compatible XVR or HDCVI DVR - it will not connect to a standard IP NVR. If your site runs entirely on IP infrastructure, a network bullet camera available through Security Australia would be the more appropriate path.

Before You Buy

Quick Fit Check

• Good match if: You are upgrading an existing coaxial cable system to 5MP and want to keep current cable runs - HDCVI transmits 5MP over up to 700 metres of existing RG59/RG6 with no additional infrastructure.
• Good match if: The camera will be mounted on a high bracket or hard-to-access position where physical lens adjustment is impractical - the 2.7-13.5mm motorised zoom is adjusted remotely through the XVR OSD after mounting.
• You may need a different model if: Your site runs on IP/PoE infrastructure - this is an HDCVI coaxial camera and will not connect to an IP NVR. A network bullet camera in the same Starlight class would be the appropriate alternative to explore on securityaustralia.com.au.

Real-World Scenarios

How It Compares

• Choose this if: You are retaining an existing coaxial cable infrastructure and need to step up to 5MP resolution with a flexible lens that can be adjusted remotely after mounting.
• You may need a different model if: Your site is IP/PoE based or requires AI-driven event detection such as perimeter intrusion analytics - a network bullet camera with onboard AI would be the more appropriate product type to consider.
• Pairs well with: A compatible Dahua XVR with UTC control support for remote lens adjustment, and a 12V DC centralised power distribution board sized for the per-camera draw of up to 12.4W.

Common Questions

1. Can I use this camera on my existing analogue DVR?

   It depends on your DVR's format support. This camera outputs HDCVI, AHD, TVI, or CVBS via a DIP switch on the cable tail. If your existing DVR supports any of these formats, it will accept the signal - but only at the resolution that DVR can handle. To get the full 5MP output, you need a compatible XVR or HDCVI DVR with 5MP channel support. A standard old-format analogue DVR will only display CVBS resolution from this camera.

2. How does the motorised zoom actually work - do I need a separate controller?

   No separate controller is required. The motorised zoom on the HAC-HFW2501TP-Z-A-27135 is controlled through the OSD menu on a compatible Dahua XVR using UTC (Up the Coax) commands sent back down the coaxial cable. You navigate to the lens control settings in the recorder's camera menu and adjust zoom and focus from there. You cannot adjust the lens using a standalone joystick or a third-party DVR that does not support UTC control - confirm your recorder has this capability before purchasing if remote lens adjustment is a requirement.

3. What is the maximum coaxial cable run for 5MP video?

   700 metres over coaxial cable at 5MP resolution, as verified through Dahua laboratory testing. For UTP cable runs using a passive HDCVI balun, the confirmed maximum is 300 metres. Cable quality matters - use RG59 or better, and avoid cable with high attenuation ratings for runs approaching the maximum. Audio transmission over coax is also supported on this camera, so the single coaxial run carries both the 5MP video signal and the built-in microphone audio back to the recorder.

4. Will this camera work in complete darkness without any external lighting?

   Yes. The camera reaches 0 lux minimum illumination when the IR LEDs are active, meaning it will produce a usable monochrome image with no ambient light at all, out to 80 metres. The Starlight sensor (0.005 lux with IR off) retains colour in very low but non-zero light levels. Smart IR adjusts the LED intensity automatically as subjects move closer, preventing overexposure at short range. For colour footage in complete darkness, an external white-light illuminator would be needed - this camera does not produce colour in zero-lux conditions.

5. Does this camera support PoE?

   No. This is an HDCVI coaxial camera that requires 12V DC power, not PoE. Maximum draw is 12.4W with IR active. It does support Power over Coax (PoC) if paired with a compatible Dahua PoC-capable XVR, which delivers 12V DC down the coaxial cable itself - eliminating the need for a separate power run to the camera. If your site runs on PoE switches and IP infrastructure, this camera is not compatible and a PoE network camera would be the appropriate alternative.

6. What are the DORI distances at wide and tele end, and what does that mean for my installation?

   At the wide end (2.7mm / 102 degrees): Detect 64m, Observe 26m, Recognize 13m, Identify 6m. At the tele end (13.5mm / 29 degrees): Detect 222m, Observe 89m, Recognize 44m, Identify 22m. In practice, this means at the tele end you can detect a person at 222 metres but you would need the subject within 22 metres for face-level identification. If your application requires recognition of a person at 40-44 metres - such as reading a uniform or confirming identity at a gate - the tele end covers that scenario. For a loading dock where you need to identify faces at the dock door, set the lens closer to wide to keep the subject within the 6-13 metre recognition/identify zone. These figures follow EN 62676-4 and are a planning guide, not a guarantee of evidentiary quality in all conditions.

7. Is the audio recording from the built-in microphone stored on the recorder?

   Yes, provided your XVR or HDCVI DVR supports audio recording on the relevant channel and has audio recording enabled in settings. The built-in microphone transmits audio over the coaxial cable to the recorder using HDCVI's 4-signal-over-coax capability - video, audio, data, and power share the single cable run. No separate audio cable is required. Check that your recorder has audio channels assigned and that the channel is configured for audio in the recording schedule, as some recorders disable audio recording by default and it must be activated per-channel. The camera's audio input port also accepts an external microphone if preferred over the built-in unit. Supplied by Security Australia with the manufacturer warranty intact.
