Dahua WizSense DVR: How AI Eliminates False CCTV Alarms in Chennai Homes and Businesses

Traditional CCTV motion detection treats everything that moves the same way — a stray dog crossing the frame sends the same alert as an intruder at your gate. The Dahua DH-XVR-4B04-I WizSense DVR changes this with AI-based Smart Motion Detection Plus (SMD+) that classifies objects in real time as humans, vehicles, or irrelevant motion — and only alerts you for the first two.

WizSense SMD+ Explained

SMD+ is embedded deep learning directly in the DVR chip. Every frame of video is analysed in real time. The AI identifies human body shapes and vehicle silhouettes with high accuracy and suppresses everything else. The result: you receive push notifications only when a person or vehicle enters your defined detection zone. Overnight false alerts from cats, rain, and shadows become history.
