You’ll learn:

How to connect and configure a USB webcam on Raspberry Pi 5
Setting up motion detection using Python + motion feed detection
Automatically recording video clips when motion is detected
Sending alerts and video files directly to Telegram
Tips for reliability, performance, and home surveillance use cases
If you’re building a DIY security system or experimenting with Raspberry Pi automation, this tutorial is perfect for you.

🔧 Tools & Technologies Used:

Raspberry Pi 5
USB camera
Python + OpenCV
Telegram Bot API
Motion detection scripting

telegram helper:

Code:
import telegram
import os
import sys

Configuration
BOT_TOKEN = 'HTTP API url'
CHAT_ID = 'xxxxxxxxxxxxxxxxxx'
VIDEO_DIR = '/var/lib/(dir name)'
def send_alert(video_file):
bot = telegram.Bot(token=BOT_TOKEN)
with open(video_file, 'rb') as f:
bot.send_message(chat_id=CHAT_ID, text="Motion detected!")
bot.send_video(chat_id=CHAT_ID, video=f)
if _name_ == '__main__':
latest_file = max([os.path.join(VIDEO_DIR, f) for f in os.listdir(VIDEO_DIR)], key=os.path.getctime)
send_alert(latest_file)

Delete videos from your Pi storage:

cd /var/lib/(your dir) || exit 1
find . -type f -name "*.mkv" -mmin +360 -delete
