Extra Info
SMD Plus
The camera is equipped with Smart Motion Detection Plus (SMD Plus), an AI-enhanced feature that intelligently filters motion events, distinguishing between humans, vehicles, and non-threatening motion like falling leaves, small animals, or shadows. This leads to a significant reduction in false alarms, helping users focus only on events that matter. Whether it’s used in a residential driveway or around a commercial property, SMD Plus provides more reliable alerts and reduces the need to review irrelevant footage.
AI Perimeter Protection
Ideal for securing specific boundaries or high-risk zones, this camera supports AI-driven tripwire and intrusion detection. It can:
- Identify whether the intruder is a human or a vehicle
- Send targeted alerts based on object type
-
Trigger recordings or actions (e.g., sirens, notifications)
This smart classification improves accuracy and is especially beneficial for fences, loading docks, private entrances, or construction zones—anywhere you want to prevent unauthorized access.
Starlight Low-Light Imaging
Thanks to a sensitive image sensor and optimized optics, the camera captures color video even in lighting conditions as low as 0.007 Lux. This is much lower than standard IR cameras that switch to black-and-white prematurely. The Starlight performance ensures that even at dusk, dawn, or dim environments, you’ll still get clear, colorful video, which is especially important for identifying clothing, vehicles, or fine scene details.
Cyber Security Protection
Designed with modern threats in mind, this camera includes multiple layers of cybersecurity protection:
-
Firmware encryption to ensure only authenticated software runs on the device.
-
IP/MAC filtering for controlling which devices can access the camera.
-
Secure boot ensures that the device starts using only trusted code.
-
HTTPS protocols for encrypted data transmission.
-
User access controls to restrict and manage logins.
These features help guard against unauthorized access, hacking attempts, or data breaches, making the camera suitable for enterprise, government, or remote-access deployments where privacy and system integrity are critical.
When paired with a Dahua AI-capable NVR, the IPC-HDBW3841R-Z(A)S supports AcuPick search, which uses AI metadata from the camera to help you instantly locate footage involving people or vehicles—without watching hours of video.
Benefits via AI NVR Integration:
- Smart filters: human/vehicle/mask/clothing
- Search by event type (e.g., tripwire trigger)
- Intelligent playback: skip idle scenes
- Supports multiple AcuPick-compatible cameras simultaneously
Q&A
Q: Does this camera support color at night?
A: It uses Smart IR for black-and-white night vision, but Starlight improves low-light color before switching.
Q: What’s the main difference between Z and ZAS models?
A: ZAS includes audio and alarm I/O ports. If you need external mic/speaker or wired alarm input, get the ZAS.
Q: Is this a TiOC model?
A: No. It doesn’t have flashing lights or sirens. It's focused on video intelligence and durability.
Q: Can it record without an NVR?
A: Yes. With a MicroSD card installed (up to 256GB), it can record locally and be viewed through the app.
Q: Will it work with my third-party NVR?
A: Yes. It supports ONVIF (Profiles S/G/T) for wide compatibility.
Q: Is remote zoom/focus possible?
A: Yes. The vari-focal lens is fully motorised. You can adjust FOV via web, NVR, or app.
