Extra Info
Smart Motion Detection (SMD 4.0)
Enhanced with more refined AI algorithms, SMD 4.0 reliably identifies motion events caused by people or vehicles while ignoring distractions like animals, wind-blown debris, or moving shadows. When used with a Dahua AI NVR, users can instantly filter recorded footage to view only relevant human or vehicle activity—saving time and minimizing unnecessary alerts.
AI Scene Self-Adaption (AI SSA)
AI SSA uses intelligent real-time processing to automatically adjust image settings such as brightness, contrast, and sharpness. Whether facing glare from sunlight, dense fog, heavy rain, or dim lighting, the camera optimizes its video output to ensure critical details remain visible and clear.
AI-Powered Perimeter Protection
The camera supports tripwire and intrusion zone detection, enhanced with AI classification to distinguish between humans and vehicles. This reduces false triggers and ensures higher accuracy in real-time intrusion monitoring—ideal for securing driveways, fences, parking lots, and building entrances.
Smart Compression (H.265+ / H.264+)
To reduce bandwidth and storage usage without compromising image quality, the camera uses Smart H.265+ or H.264+ encoding. These advanced compression technologies can lower storage requirements by up to 70% compared to traditional H.264, making the system more cost-effective and efficient—especially in long-term recording setups.
