Home security system with Raspberry Pi

Home security system with Raspberry Pi and sending notifications with a Telegram bot

Tutorial to build a home security system with Raspberry Pi and sending notifications with a Telegram bot

How it works

When a movement is detected, the application records a video that is sent to your phone by the bot.
Once installed, the monitoring system is managed from your smartphone with the bot's commands.
The system is started by a systemd service activated at boot time

Prerequisites

• Raspberry Pi Camera Module
• PIR motion sensor module
• 3 female-to-female jumper wires
• Tutorial for create your Telegram Bot
• After starting the bot on your smartphone, you must retrieve your chat_id at the following address :https://api.telegram.org/bot<token_id>/getUpdates

Connect the PIR sensor

The PIR must be spaced from the Raspberry Pi to avoid interference with WiFi. WiFi waves can trigger the PIR and create false positives

Setup

• Open the config.py file and configure the TOKEN_ID and CHAT_ID variables with your token_id and your chat_id

# Variable to configure
TOKEN_ID = 'Your token_id'
CHAT_ID = 'Your chat_id'

Installing

The installation requires root rights:

A reboot will be done at the end of the installation to activate the camera hardware

sudo make install

or

sudo su 
make install

Bot's commands

• /start : start the home monitoring system
• /stop : stop the home monitoring system
• /status : show the status of the monitoring system
• /photo : take a picture
• /video <delay> : records a video, by default delay is 60s
• /clean : remove all files in video folder
• /help : show help

Details

• By default, the duration of the video is set to 60s. If you want change this, you need to modify the VIDEO_TIME constant in config.py
• It's possible to add other commands to the bot in app.py

Testing

make test

Uninstall

sudo make uninstall

A reboot will be done at the end to deactivate the camera hardware
