This determines **when** an alert should be triggered.
- For simple events (like Vape or Keyword Detection), the trigger is usually **"At Once"**, meaning the alert goes off immediately when detected.
- For others (like Smoking or Aggression), it's **threshold-based**, meaning the event must exceed a certain level (e.g., noise level, particulate matter) before it triggers an alert.
**Example:**\
If the aggression threshold is set to 80, the system will trigger an alert when the detected noise level goes above 80 decibels.
