Extra Info
SMD 4.0 (Smart Motion Detection)
SMD 4.0 uses AI to detect and classify motion caused specifically by people and vehicles. This helps eliminate alerts from pets, shadows, or waving trees, ensuring only relevant events are recorded.
AI SSA (Scene Self-Adaption)
AI SSA automatically adapts the image settings to different lighting or weather conditions—such as fog, rain, or backlight—so you always get a clear and balanced picture, day or night.
Quick Pick with AI NVR
When used with a compatible AI NVR, Quick Pick makes it easy to find and filter human or vehicle footage from motion events—saving time during playback and investigations.
Smart Codec Technology
Dahua’s Smart H.265+ and H.264+ reduce video file sizes while keeping clarity, optimizing both bandwidth use and storage costs—ideal for long-term recording.
Cybersecurity Protection
Includes security features like video encryption, account lockout, IP filtering, and secure firmware updates—helping prevent unauthorized access to your system.
