The Dahua IPC-HFW3866EP-AS-AUS is a robust 8MP fixed-lens bullet camera built for clear outdoor surveillance. With advanced AI features like perimeter protection, scene self-adaptation, and smart motion detection, it minimizes false alarms and ensures critical activity is captured accurately. Ideal for a range of scenarios, it delivers crisp video in daylight and low-light conditions.
Key Features
-
AI Human/Vehicle Detection: Reduces false alarms with smart classification of people and vehicles.
-
Built-in IR Illumination (30m): Enables clear black-and-white video in total darkness.
-
Smart Motion Detection 4.0: Prioritises meaningful motion events while filtering out irrelevant ones.
-
AI SSA (Scene Self-Adaption): Automatically adjusts image settings for optimal clarity in fog, backlight, and rain.
-
Built-in Microphone: Captures ambient audio for enhanced situational awareness.
-
Fixed Lens Options (2.8mm / 3.6mm): Wide and mid-range views for different coverage needs.
-
Smart H.265+/H.264+ Compression: Reduces file size and storage use without compromising quality.
-
IP67 Weather Protection: Designed for year-round outdoor use.
Perfect For:
- Residential driveways and gates
- Commercial building entrances
- Loading docks or delivery areas
- Public sidewalks and walkways
- Outdoor retail zones
-
School or hospital perimeters
Install Tips
- Mount between 2.5–3.5 metres high for best person/vehicle detection.
- Use 2.8mm for wide areas like parking lots; use 3.6mm for focused entry points.
- Pair with Dahua AI NVR for Quick Pick search and deeper AI features.
- Use PoE for easier cable management and single-wire power/data.
-
Avoid direct sun glare — AI SSA helps, but proper angle improves image quality.

Extra Info
Smart Motion Detection (SMD 4.0)
Dahua’s most advanced AI-powered motion detection, SMD 4.0 smartly filters out irrelevant movement from animals, wind-blown leaves, or shadows, focusing only on humans and vehicles. When used with a Dahua AI NVR, users can take advantage of "Quick Pick" search, making it faster to find relevant video clips by object type.
AI SSA (Scene Self-Adaption)
Scene Self-Adaption (SSA) automatically fine-tunes image settings such as exposure, brightness, and contrast based on real-time environmental conditions. Whether it’s foggy, backlit, or overcast, SSA ensures clear, optimized footage without the need for manual adjustments.
Built-In Audio
An integrated microphone captures ambient audio, providing audio context to accompany video footage. This can improve incident understanding during playback. If connected to external speakers, the camera also supports two-way audio, allowing real-time communication through the system.
Smart Encoding (H.265+/H.264+)
This intelligent compression method analyzes each scene and applies heavier compression to static areas, preserving quality in motion zones. The result: reduced bandwidth use and lower storage requirements, perfect for 24/7 recording without increasing server costs.
Cybersecurity Features
To guard against modern threats, this model includes:
- Encrypted transmission protocols
- Access control permissions
-
Firmware integrity verification
These measures ensure the system is resistant to unauthorized access, data leaks, and firmware tampering, keeping your surveillance network secure.
While the IPC-HFW3866EP-AS-AUS does not feature built-in AcuPick, it supports AcuPick search when paired with a Dahua AI NVR. The camera streams metadata (e.g., human/vehicle classification) that enables fast filtering and playback using object-based 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
Can this record in colour at night?
No, this model uses IR for night vision, so footage is black and white in low light.
How far can it see in the dark?
Up to 30 metres with built-in IR illumination.
Is the microphone always recording?
Yes, if enabled. It records ambient audio continuously unless configured otherwise.
Can the audio be disabled?
Yes. You can disable audio recording through the camera or NVR settings.
Does it work with non-Dahua NVRs?
Yes, via ONVIF support. However, advanced AI features may require a Dahua AI NVR.
How long does 256GB of storage last?
That depends on your settings. With Smart H.265+ at moderate quality, it can last several days to over a week.
Does it support tripwire or intrusion detection?
Yes — with human/vehicle classification to reduce false alerts.
What makes this different from TiOC models?
This model focuses on passive monitoring (no lights or sirens). TiOC models add active deterrence features like red/blue lights and audio alerts.
