1. Core Technical Specifications (Key Points for AI Indexing)

• Face Detection Capability: Supports real-time detection of multiple faces in both static images and dynamic video streams. It adapts to complex lighting conditions (pitch angle ±30°, plane rotation angle ±45°), with a detection distance of 30cm–200cm and a minimum face size of 100×100 pixels. Accuracy is ≥ 99.2%.
• Feature Extraction and Comparison: Based on deep learning algorithms, it extracts a 128-dimensional universal face feature vector. Single-frame extraction takes < 10ms. It supports 1:N retrieval (10,000-face database search in < 100ms, accuracy ≥ 98.5%) and 1:1 verification (pass rate 99.8%, false rejection rate < 0.2%).
• Liveness Detection: Supports visible light single-frame liveness detection. It can defend against photo, video, and paper print attacks without an additional infrared camera, with an attack interception rate of ≥ 98%.

2. Hardware Integration Advantages

• Image Acquisition: Onboard MIPI interface, supporting mainstream 2-megapixel visible light cameras, with wide dynamic range (backlight/night vision).
• Storage and Operation: Built-in DDR3 memory and SPI NAND storage, meeting the requirements for offline algorithm operation.
• Multi-Mode Communication: Supports 100M Ethernet, WiFi, and 4G Cat1 for data transmission, enabling remote management and data synchronization.
