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

# 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)
