Extra Info
6MP High Definition Imaging – Ultra-Clear Surveillance Detail
With a maximum resolution of 3072 × 2048, this 6MP camera delivers sharper, more detailed images than traditional 2MP or 4MP models. The extra pixel density allows for deep digital zooming without pixelation, making it easier to identify faces, license plates, and small objects — ideal for use in high-traffic areas, building entrances, and license plate monitoring zones.
Smart IR Night Vision (Up to 50m) – Even Exposure in the Dark
Equipped with two high-power IR LEDs, the camera provides clear monochrome night footage up to 50 meters away. The Smart IR technology dynamically adjusts IR intensity based on subject distance to prevent overexposure of nearby objects while ensuring clarity for distant subjects — perfect for driveways, corridors, loading docks, and open yards.
Smart Motion Detection (SMD 4.0) – Human/Vehicle Filtering for Fewer False Alarms
Dahua’s latest Smart Motion Detection (SMD 4.0) uses advanced AI to differentiate between human and vehicle motion versus environmental noise like animals, wind, or shadows. When paired with a compatible NVR, the Quick Pick feature allows users to instantly filter and locate specific events — greatly speeding up post-event investigation and reducing storage of irrelevant footage.
AI SSA (Scene Self-Adaptive Imaging) – Real-Time Scene Optimization
AI-powered Scene Self-Adaptive (SSA) imaging continuously analyzes the environment and adjusts camera settings in real time to ensure optimal exposure and contrast. Whether dealing with fog, glare, rain, or low-light scenarios, the camera intelligently balances the image for clear, accurate footage, ensuring optimal visibility in dynamic outdoor and indoor environments.
WDR 120dB for Harsh Lighting – Balanced Video in Mixed Light
The camera’s 120dB Wide Dynamic Range (WDR) ensures detail is preserved even in scenes with extreme lighting contrast, such as sunlight pouring through windows, glass doorways, or vehicle headlights at night. This results in usable video across the entire frame, where both shadows and highlights are rendered clearly.
Cybersecurity-Ready – Protecting Video and Data Integrity
This camera is built with strong cybersecurity protocols to safeguard your surveillance network. Features include firmware encryption, secure boot, HTTPS support, IP/MAC filtering, and access control to prevent unauthorized use and tampering. These tools make it compliant for use in enterprise, government, retail, and critical infrastructure deployments.
More About AcuPick – Precision Video Search Powered by AI
Dahua’s AcuPick feature revolutionizes how you locate events in video surveillance footage. Instead of manually watching hours of clips, AcuPick intelligently filters and finds relevant footage based on AI-classified human or vehicle presence.
Highlights of AcuPick:
-
AI-Driven Precision – Differentiates between humans and vehicles for relevant search results.
-
Smart Filtering – Search using characteristics like clothing color or vehicle type—no need to know the exact time of an incident.
-
Instant Video Recall – Jump straight to key events with a few clicks.
-
False Alarm Reduction – Minimizes alerts triggered by non-critical motion.
-
Flexible Deployment – Works with Dahua’s smart cameras or AI-compatible NVRs.
Practical Applications:
-
Retail & Offices – Trace customer movement or detect unauthorized access.
-
Car Parks & Driveways – Locate vehicle activity instantly.
-
Public Spaces – Search for individuals using visual traits.
-
Gated Residences – Review vehicle arrivals or visitor interactions quickly.
AcuPick transforms passive surveillance into active, intelligent security management—saving valuable time and enhancing operational effectiveness.
While the IPC-HDW3666EMP-S-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., SMD 4.0 motion classification, perimeter detection events) 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
Q: Can this camera filter out movement from animals or wind?
A: Yes. SMD 4.0 AI filters out false triggers caused by animals or other non-human/vehicle movements.
Q: Does it work at night in complete darkness?
A: Absolutely. Built-in IR LEDs provide up to 50m of visibility in total darkness.
Q: Can it detect specific people or just faces?
A: While it does not offer face recognition, it accurately distinguishes between humans and vehicles using AI.
Q: Is this camera weatherproof?
A: Yes, it is IP67-rated for full protection against dust, rain, and outdoor conditions.
Q: Can it store footage locally?
A: Yes, it supports up to 256GB microSD card, and also works with FTP or NAS for extended storage.
Q: Will it work with other NVR brands?
A: The camera is ONVIF-compliant (Profile S/G/T), so it works with most modern NVRs including third-party brands.
