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.

"""
A class to manage security alarm functionalities for real-time monitoring.
This class extends the BaseSolution class and provides features to monitor
objects in a frame, send email notifications when specific thresholds are
exceeded for total detections, and annotate the output frame for visualization.
Attributes:
email_sent (bool): Flag to track if an email has already been sent for the current event.
records (int): Threshold for the number of detected objects to trigger an alert.
Methods:
authenticate: Sets up email server authentication for sending alerts.
send_email: Sends an email notification with details and an image attachment.
monitor: Monitors the frame, processes detections, and triggers alerts if thresholds are crossed.
Examples:
>>> security = SecurityAlarm()
>>> security.authenticate("abc@gmail.com", "1111222233334444", "xyz@gmail.com")
>>> frame = cv2.imread("frame.jpg")
