# Security Alarm System Project Using Ultralytics YOLOv8
The Security Alarm System Project utilizing Ultralytics YOLOv8 integrates advanced computer vision capabilities to enhance security measures. YOLOv8, developed by Ultralytics, provides real-time object detection, allowing the system to identify and respond to potential security threats promptly. This project offers several advantages:
- **Real-time Detection:** YOLOv8's efficiency enables the Security Alarm System to detect and respond to security incidents in real-time, minimizing response time.
- **Accuracy:** YOLOv8 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
???+ tip "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())
```

#### 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.
