The Tailgating rule can trigger an alarm when a second object passes a certain area after the first object, within a configurable period of time. We can exemplify an alarm when a car that passes along with another when a toll gate is lifted.
•Time: Time in seconds between objects entering an area. If after an object enters the area, a second object enters with a time shorter than the configured one, an alarm will be triggered.
•RearmTime: Time in which the alarm actions will be reactivated after an execution.
•Alarm actions: Click on the alarm actions line and then on the button with 3 dots as shown in the figure below:
On the alarms screen, configure the desired actions when the analytics trigger events. To learn more about alarm actions see chapter How to configure alarm actions.
