8MP Motorised Zoom Lens (2.7–13.5 mm) – Adjust field of view remotely to suit wide angles or tight zones without reinstallation.
-
Human/Vehicle AI Detection – Built-in perimeter protection filters false alerts for smarter surveillance.
-
Long-Range 60 m IR Night Vision – Clear black-and-white visibility even in total darkness.
-
Built-in Mic + Audio In/Out (ZAS Only) – Capture voices and integrate with PA or intercom systems.
-
Smart Motion Detection (SMD Plus) – Filters motion alerts from wind, trees, and animals.
-
Smart H.265+ Video Compression – Saves storage space while keeping footage crisp.
-
IP67 Weather Rating – Rugged and water-resistant, built to withstand outdoor exposure.
-
256GB microSD Storage Support – Record locally even without a network connection.
Perfect For:
- Building perimeters and long driveways
- Loading docks and warehouse entries
- Rural property gates or livestock zones
- High-traffic industrial or commercial areas
- Critical infrastructure like substations or towers
- Utility corridors and long outdoor lanes
Install Tips
-
Use Smart NVR Pairing – For full AI playback, line-cross detection, and intelligent search, use with a Dahua NVR.
-
60 m IR Coverage – Mount at 3–4 m height to optimise IR night visibility.
-
Use Zoom to Frame Entryways – Motorised lens allows remote focus for license plates or narrow doorways.
-
ZAS vs ZS – Only the ZAS model includes audio I/O and alarm inputs/outputs—important for integration.
-
Leverage Starlight + IR – Activates colour mode longer in dusk/dawn conditions before IR takes over.
-
Install with Junction Box – Use the optional PFA130-E for tidy cable protection and wall mounting.

Extra Info
ZAS vs ZS Models
Dahua offers this camera in two variants to suit different installation needs. The “ZAS” model is equipped with full audio input/output ports and alarm I/O, making it highly adaptable for advanced integrations such as connecting external microphones, speakers, sirens, or third-party alarm systems. This is ideal for environments where interactive features or active deterrence (like voice alerts) are needed.
In contrast, the “ZS” model omits these extra ports but retains all core camera functions, including video, AI detection, and remote zoom—making it a good choice for simpler installations or where audio and alarms are not required.
Motorised Lens Advantages
Equipped with a motorised vari-focal lens, this camera allows users to adjust zoom and focus remotely, even after the unit is mounted. This is especially beneficial for scenarios where the optimal field of view may change over time or is difficult to determine upfront. Whether you're monitoring warehouse corridors, gates, parking lots, or open courtyards, the camera can be adapted to the specific layout without needing a technician to revisit the site.
Perimeter Protection with AI
Using deep learning technology, the camera can intelligently detect people or vehicles that cross user-defined digital tripwires or intrusion zones. This dramatically improves accuracy compared to basic motion detection by ignoring irrelevant motion like shadows, wind-blown foliage, or animals. When used with a Smart NVR, events can be searched and filtered quickly, helping operators find specific incidents without reviewing hours of video manually.
Extended 60 m IR Night Vision
Featuring a powerful 4-LED infrared array, this camera offers nighttime visibility up to 60 meters, far beyond what standard IR-equipped models provide. The system also uses Smart IR to balance brightness, ensuring that nearby objects aren’t overexposed while distant areas remain visible. This makes it ideal for open outdoor areas, like parking lots, storage yards, or long driveways, that require consistent performance after dark.
Audio + Alarm I/O (ZAS Only)
Only the ZAS variant supports audio and alarm input/output ports. These connections allow the camera to act as more than a passive recorder—it can trigger alarms, send audio warnings, or receive signals from external devices like door sensors or panic buttons. This makes the camera a powerful component in a larger integrated security solution, especially useful for high-risk zones, access control points, or buildings with active monitoring systems.
While the IPC-HFW3841T-ZAS does not feature built-in AcuPick, it supports AcuPick search functions when connected to an AI-capable Dahua NVR. The camera sends AI metadata (e.g., face detection, people counting, perimeter classifications) that the NVR uses for smart filtering and playback search.
Benefits via AI NVR Integration:
- Search by human or vehicle presence
- Filter playback using traits like mask, gender, or clothing
- Skip irrelevant footage and jump to key events instantly
- Use AI-driven logs and smart snapshots from camera metadata
Q&A
Does this camera record in colour at night?
Yes. In low-light environments, the Starlight sensor maintains colour longer before switching to IR black-and-white.
What’s the difference between ZS and ZAS models?
The ZAS version includes audio in/out and alarm I/O. ZS does not—choose ZAS if external integrations are needed.
Is the zoom motorised and remote-controlled?
Yes. You can adjust both zoom and focus from your NVR, software, or app.
How far can it see in darkness?
The 4-LED IR system gives clear night vision up to 60 m in open areas.
Does it support local recording?
Yes. It supports microSD cards up to 256 GB, ideal for standalone or backup recording.
Can this detect cars and people separately?
Yes. With built-in AI, it classifies and alerts based on human or vehicle activity.
Is this camera weatherproof?
Yes. It’s IP67-rated, making it fully sealed against rain and dust.
Does this integrate with other systems?
Yes. It supports ONVIF for compatibility with third-party NVRs and platforms like Milestone and Genetec.
