Dear MarcosPreventista
Yes, you can create points of interest in the application using Geofences. You can create geofences of different shapes (circle, rectangle, polygon) to mark client locations or other important points on the map. When a unit enters or exits these geofences, you can receive notifications.
Regarding your second question about parking detection - a stop is registered when the unit remains stationary for more than 5 minutes. This helps distinguish between actual parking events and brief stops like traffic lights or temporary halts.
