Extra Info
Fixed-Focal Lens Benefits
Delivers crisp, consistent images without needing zoom adjustments. Ideal for fixed coverage areas—select wide-angle or focused view during installation.
Smart Motion Detection 4.0
AI-powered motion detection reduces false alarms caused by animals, leaves, or rain. Works best when paired with an AI NVR to enable Quick Pick smart playback by object type.
AI Scene Self‑Adaption (AI SSA)
Automatically adjusts exposure, contrast, and color in difficult lighting such as fog, glare, or shadows, ensuring clear, balanced footage.
Built-in Audio & Alarm I/O
Captures ambient audio and allows integration with external speakers or alarms.
Rugged Housing (IP67 & IK10)
Withstands rain, dust, and physical tampering, making it reliable for outdoor or high-risk environments.
Smart Compression
Smart H.265+ and H.264+ algorithms adjust video compression based on motion and scene complexity, optimizing storage and network efficiency.
Cybersecurity Protection
Equipped with firmware encryption, secure user access, and network protection features to prevent unauthorized access and ensure data integrity.
While the IPC-HDBW3866EP-AS-AUS 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
Can this camera record in full color at night?
No. It uses IR to provide black-and-white night vision. Color remains available during low‑light conditions only.
How far does the microphone pick up sound?
The built-in mic captures audio clearly within a few meters—distance depends on ambient noise.
Can the audio and alarm inputs be turned off?
Yes. Both the microphone and audio/alarm I/O can be disabled via the camera’s settings.
Does it work with non-Dahua NVRs?
Yes, it's ONVIF compliant. But to access Quick Pick and event classification, using a Dahua AI NVR is recommended.
How long does recording last on a 256 GB card?
With smart compression and moderate activity, expect 5–10 days of continuous footage; actual time varies by usage and motion levels.
Will trees or rain trigger false alarms?
SMD 4.0 filters these out. However, configuring detection zones manually improves accuracy.
Does IK10 mean it's vandal-proof?
Yes—it withstands impacts equivalent to a 5 kg object dropped from 40 cm.
What’s the difference between the EP-AS and other variants?
This model offers fixed-focal lenses. Other variants may include motorized zoom or active deterrence features like lights or sirens.
