Unlock a Door With Face Recognition Using ESP32 Camera

Introduction

Face recognition have been used in smartphone in past few years. It is a cool technology where you can unlock your phone or to access any application that require high security. With ESP32-CAM, we can try to develop a simple application that use your face as ID. Since ESP32 board package already comes with CameraWebServer example code that cater for video stream and face recognition, let’s try to modify a bit so that it can control a relay to ON and OFF.
