| Function | Description |
|---|---|
| SMD Plus | Dahua Smart Motion Detection (SMD) technology employs an intelligent algorithm to categorise motion-triggered targets, filtering out alarms from non-relevant sources. This ensures effective and accurate motion detection alerts. |
| Smart H.265+ & Smart H.264+ | Dahua’s smart encoding technology, utilising an advanced scene-adaptive rate control algorithm, achieves higher encoding efficiency compared to H.265 and H.264. This results in high-quality video, reducing storage and transmission costs. |
| Perimeter Protection | Dahua Perimeter Protection technology, driven by deep learning algorithms, accurately recognises humans and vehicles. In restricted areas, false alarms from intelligent detection based on target types (e.g., tripwire, intrusion) are significantly reduced. |
| WDR | Advanced Wide Dynamic Range (WDR) technology in Dahua network cameras ensures clear details in environments with strong brightness contrast. The camera delivers clear video in high brightness conditions or areas with backlight shadows. |
| Cyber Security | Dahua network cameras employ a range of security technologies, including security authentication and authorisation, access control protocols, trusted protection, encrypted transmission, and encrypted storage. These measures enhance the camera’s defence against external cyber threats and prevent compromises by malicious programs. |
| Protection (IP67, Wide Voltage) | – IP67: The camera undergoes rigorous tests for dust and water resistance, achieving dust-proof functionality. It can operate normally after soaking in 1 m deep water for 30 minutes. – Wide voltage: The camera tolerates ±30% input voltage fluctuations (for some power supplies), making it suitable for outdoor environments with unstable voltage conditions. |
