Extra Info
Smart Motion Detection (SMD Plus)
This camera is equipped with Dahua’s SMD Plus technology, which uses artificial intelligence to distinguish between humans, vehicles, and irrelevant motion. Unlike traditional motion detection that reacts to any movement, SMD Plus intelligently filters out distractions such as swaying branches, rain, pets, or passing shadows. The result is significantly fewer false alarms, allowing for more focused monitoring and efficient security response.
Starlight Performance in Low-Light Scenes
Designed for superior low-light performance, Dahua’s Starlight technology enables the camera to capture vivid, full-color images even in dim lighting conditions. This reduces the dependency on infrared lighting and allows operators to identify clothing colors, vehicle types, and other critical visual details earlier in the evening — before the scene becomes fully dark.
Perimeter Protection Intelligence
Using deep-learning algorithms, the camera enhances perimeter security with AI-powered tripwire and intrusion detection. These rules are activated only when a person or vehicle crosses a virtual boundary or enters a restricted area. This minimizes nuisance alerts and boosts the accuracy of real-time notifications, making it especially effective for high-priority zones like property lines, loading bays, school grounds, and building entrances.
High-Efficiency Storage with Smart Codec (H.265+/H.264+)
The camera features Smart Codec technology that optimizes video compression based on real-time scene complexity and motion activity. By reducing unnecessary data from low-motion or static scenes, it significantly decreases file sizes — saving up to 70% in storage and bandwidth compared to standard codecs. This is ideal for continuous 24/7 recording environments with storage limitations or remote cloud uploads.
Cybersecure by Design
Built with cybersecurity in mind, this camera includes a suite of protective features such as HTTPS encryption, digest authentication, firmware signing, and security logs. These defenses help prevent unauthorized access, tampering, and data breaches — aligning with modern data protection standards and making the camera a safe choice for sensitive or regulated installations.
The DH-IPC-HFW3541E-AS does not feature onboard AcuPick, but it does support AI metadata generation (like person/vehicle detection via SMD Plus). When paired with a compatible Dahua AI NVR, this metadata can be used to enable AcuPick—Dahua’s intelligent search tool that quickly filters and finds key footage events.
Benefits with Compatible NVR:
- Filter recordings based on human or vehicle detection
- Search by appearance details (e.g., color or vehicle type)
- Jump directly to critical moments
- Avoid watching hours of irrelevant footage
Q&A
Q: Does this camera support audio recording?
