Extra Info
AI Detection Built In
The camera comes with Dahua’s WizSense AI platform, enabling it to intelligently detect and classify objects in real time. It can distinguish between humans, vehicles, and irrelevant motion such as moving leaves, animals, or shifting shadows. When paired with SMD Plus (Smart Motion Detection), the system dramatically reduces false alarms and ensures that only genuine threats trigger alerts. This makes it ideal for installations where reliability and minimal false positives are critical—like residential areas, warehouses, or retail storefronts.
Starlight Technology
The HDW3641EM-S-S2 model features advanced Starlight imaging, using a high-sensitivity sensor to extend the capture of color video in extremely low-light environments. This enhances the ability to identify details like clothing color or vehicle type even before switching to infrared mode. It provides better context and forensic value in environments with limited lighting, such as alleyways, perimeter zones, or parking lots.
Fixed Lens Options for Simplicity
To simplify deployment and minimize maintenance, the camera offers two fixed focal lengths:
-
2.8 mm lens: Delivers a wide-angle view perfect for covering large spaces like building entrances, lobbies, or courtyards.
-
3.6 mm lens: Provides a narrower field of view, ideal for hallways, corridors, or targeting specific areas like cash registers or gates.
These lens options let you choose the right coverage without needing a vari-focal or zoom mechanism—keeping the setup straightforward and durable.
Built-in Microphone
Integrated into the camera body is a high-sensitivity microphone capable of recording ambient sound and voices. This eliminates the need for external audio equipment and allows for synchronized audio-video evidence, making it valuable for incident reviews, dispute resolution, or monitoring customer interactions in commercial settings.
Smart H.265+ Saves Storage
The camera supports Smart H.265+ compression, which uses intelligent scene analysis to adjust bitrate and compression dynamically. This means:
- Sharper video during motion
- Lower bitrate during static scenes
-
Up to 70% savings on storage and bandwidth compared to traditional H.264
It’s especially useful for installations using MicroSD cards, limited bandwidth connections, or setups requiring longer recording retention.
Cybersecurity Certifications
For users concerned with data privacy and system integrity, this model complies with globally recognized cybersecurity standards, including:
-
UL CAP (Underwriters Laboratories Cybersecurity Assurance Program)
- TÜV Rheinland IoT Device Certification
-
ETSI EN 303 645 for consumer IoT security
Security features include:
- Encrypted video streams
- Secure user authentication
-
Trusted firmware updates
These safeguards help protect your system from unauthorized access, data leaks, or cyberattacks, making it ideal for enterprise and government deployments.
While the IPC-HDW3641EM-S-S2 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 color at night?
Yes. Thanks to Starlight technology, it maintains color longer in dim lighting before switching to IR mode.
How far can the IR see?
Up to 50 m in ideal conditions, thanks to its dual IR LED array.
Does it support audio recording?
Yes. A built-in microphone allows for on-site audio capture without extra hardware.
Is this camera good for outdoor use?
Yes. Its IP67 rating ensures it withstands rain, dust, and heat down to -40°C.
What lens should I choose?
Use 2.8 mm for wide areas like front yards or wide driveways, and 3.6 mm for narrower or deeper views like hallways or parking lanes.
Does it support SD card recording?
Yes, it supports microSD cards up to 256 GB for local storage.
Can I access footage from my phone?
Yes. Use the DMSS mobile app for live view, playback, and push notifications.
Will this work with other NVR brands?
Yes. It supports ONVIF and can work with most major third-party NVRs like Milestone or Genetec.
