<img src="https://github.com/ultralytics/docs/releases/download/0/security-alarm-system-ultralytics-yolov8.avif" alt="Security Alarm System">

The Security Alarm System Project utilizing Ultralytics YOLO11 integrates advanced [computer vision](https://www.ultralytics.com/glossary/computer-vision-cv) capabilities to enhance security measures. YOLO11, developed by Ultralytics, provides real-time [object detection](https://www.ultralytics.com/glossary/object-detection), allowing the system to identify and respond to potential security threats promptly. This project offers several advantages:

- **Real-time Detection:** YOLO11's efficiency enables the Security Alarm System to detect and respond to security incidents in real-time, minimizing response time.
- **[Accuracy](https://www.ultralytics.com/glossary/accuracy):** YOLO11 is known for its accuracy in object detection, reducing false positives and enhancing the reliability of the security alarm system.
- **Integration Capabilities:** The project can be seamlessly integrated with existing security infrastructure, providing an upgraded layer of intelligent surveillance.

### Code

#### Set up the parameters of the message

???+ note

    App Password Generation is necessary

- Navigate to [App Password Generator](https://myaccount.google.com/apppasswords), designate an app name such as "security project," and obtain a 16-digit password. Copy this password and paste it into the designated password field as instructed.

```python
password = ""
from_email = ""  # must match the email used to generate the password
to_email = ""  # receiver email
```

#### Server creation and authentication

```python
import smtplib

server = smtplib.SMTP("smtp.gmail.com: 587")
server.starttls()
server.login(from_email, password)
```

#### Email Send Function

```python
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


def send_email(to_email, from_email, object_detected=1):
    """Sends an email notification indicating the number of objects detected; defaults to 1 object."""
    message = MIMEMultipart()
    message["From"] = from_email
    message["To"] = to_email
    message["Subject"] = "Security Alert"
    # Add in the message body
    message_body = f"ALERT - {object_detected} objects has been detected!!"

    message.attach(MIMEText(message_body, "plain"))
    server.sendmail(from_email, to_email, message.as_string())
```

        cv2.destroyAllWindows()
        server.quit()
```

#### Call the Object Detection class and Run the Inference

```python
detector = ObjectDetection(capture_index=0)
detector()
```

That's it! When you execute the code, you'll receive a single notification on your email if any object is detected. The notification is sent immediately, not repeatedly. However, feel free to customize the code to suit your project requirements.
