I have made a geoevent service to detect a car to enter a geofence and I want to send a Email when the car enter the geofence, but it will keep sending when the car inside the geofence until it is outside.I dont know how to deal with it.
There should be a difference (Inside should give multiple results, while Enter should only provide one):

Are you sure that it enters the GeoFence only once? If it is a narrow GeoFence following the route of a car, GPS imprecision may invoke multiple entries.
