AI video event detection and recording system based on EventCAM 2D upgrade. On the basis of retaining the original functions, it adds an AI engine and DSP engine to greatly enhance the AI processing capabilities at the edge. Run a lightweight algorithm model and real-time system to quickly and accurately realize personnel presence detection, action classification, trajectory classification and anomaly detection. It provides 4K@240fps ultra-high resolution and frame rate, and deeply optimizes the self-developed AI model based on heterogeneous chip architecture. Embedded low-latency encoded IP and ISP modules ensure high-quality imaging.
