The Loitering rule can trigger alarms if it detects an object transiting in a certain area for a certain time.
Let's configure a Loitering alarm from a zone. In the figure below, a zone was created in the previously calibrated image:
With the zone selected select the Loitering rule. The options for this rule are as follows:
•Time: Time the object has to stay still to trigger the alarm.
•Rearm Time: 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.
