Extra Info
Smart Motion Detection (SMD) 3.0
Powered by artificial intelligence, SMD 3.0 accurately identifies motion caused by people and vehicles, while intelligently filtering out non-threatening movement like pets, leaves, rain, or light changes. This significantly reduces false alarms and ensures that notifications and recordings focus on true security events — saving time and boosting surveillance efficiency.
Built-in 4G Connectivity
Equipped with a built-in 4G module, this camera can connect directly to cellular networks by inserting a SIM card. This allows the device to transmit video data remotely or to the cloud without relying on Wi-Fi or wired internet infrastructure. It’s the ideal solution for remote or temporary locations such as construction sites, farms, or areas without reliable network access.
AI-Enhanced Perimeter Protection
Utilizing intelligent tripwire and intrusion detection features, the camera can determine whether a person or vehicle has entered a defined area. This AI-based classification helps reduce nuisance alerts and enables faster, more targeted responses — making it well-suited for securing boundaries, entrances, and restricted areas.
Privacy Masking & Smart IR
To comply with privacy regulations and protect sensitive areas, users can configure up to 8 privacy zones that blur specific regions of the video frame. In addition, Smart IR technology automatically adjusts infrared lighting to prevent overexposure of close-up objects at night, ensuring balanced and clear night-time images.
Seamless System Integration
The camera integrates smoothly with Dahua’s complete ecosystem — including NVRs, the Smart PSS desktop application, and the DMSS mobile app for live viewing and alerts. It also supports ONVIF standards, allowing for easy compatibility with third-party video management systems and devices, providing flexibility for various deployment scenarios.
