# SoA Course Project - Intelligent Doorbell
###### tags: `Python3` `SoA`
## Introduction
Smart Doorbell is a home monitoring system that contains monitoring devices - ESP32 and web services, This project involoved IoT, Web design and server management. The device can easilly connect to the Wi-Fi by smartphone app "ESP SmartConfig", after successfully connected to internet, it will start detection and post picture to server, then user can use the browser to see all the picture which captured by devices.
The monitoring device uses PIR sensors to detect people or objects and uses a camera module to take pictures, and then sends the pictures to a file server, and it can be multiple devices.
The webpage can view the pictures on the file server and provide some command to control the monitoring device, like reboot device, take picture manually, set device name.

## System Architecture  
  
### Server  
  
- WebServer  
	- Django -  “Base on Python”  
		- Picture gallery  
		- Sent commands.  
			- Reset module  
			- Set module name  
			- Take picture manually  
			- Get/Sync module time  
- File server  
	- Save Picture to Folder  
  
### Module  
  
- PIR Sensor  
- ESP32-CAM  
	- Take picture  
	- UDP Client recv. commands.  
	- FTP Client Sent. images.  
	- SNTP (Time Sync) Time as picture name  
  
## Features  
  
### WiFi SmartConfig  
  
### Reset WiFi config by button  
  
### Indicate LED  
  
### BSD Socket API
