The greatest advantage of this model is full integration with intelligent AI image analysis, such as SMD Plus. This system effectively eliminates false alarms triggered by rain, leaves, or small animals, focusing security attention on real threats – humans and motor vehicles. The recorder supports perimeter protection functions, allowing for precise setting of virtual barriers. System management is extremely simple and intuitive thanks to the free DMSS application for mobile devices. P2P cloud technology means that remote viewing from anywhere in the world does not require a public IP address or complicated router configuration. The device supports one SATA drive with a capacity of up to 20 TB, which guarantees a long recording archive time. A solid housing and a wide operating temperature range from -10°C to 55°C make it an ideal solution for both single-family homes and small retail outlets or offices. The recorder is equipped with a 4K HDMI and VGA output, allowing for convenient connection to modern monitors and televisions.
