Project Details
How It Works
The ESP32-CAM captures images using its onboard OV2640 camera. The ESP32 dual-core processor runs AI algorithms for face detection and recognition. For face detection, it uses edge AI processing directly on the device. For recognition, it can store faces in local memory. Optionally, images can be sent to cloud AI services like Google Vision for more advanced classification. The system connects via WiFi to stream video and can trigger actions like activating a relay or buzzer based on recognition results.
Prerequisites
Basic knowledge of Arduino programming, familiarity with ESP32 boards, understanding of WiFi connectivity, and some experience with AI concepts would be helpful. Users should also be aware of privacy considerations when implementing face recognition.
