"Self-Generated" Geozones by Ignition

Hi Guys and Ladies,

we are getting more and more often the request for a special anti theft solution.
Our customers would like to receive alarm messages, if the car is moved AND IGNITION is off.

As i understand Wialon, this is only possible by using Geozones. (Please correct me if i am wrong).
So in my eyes a great function would be the following:

Wialon can be configured for individual device, that a Geozone with radius=xxx meters (Circle) is generated for the last position where Ignition is gone from 1 to 0.
This geozone is used as dynamic geozone with alarms if geozone is left by device.

If Engine goes from 0 to 1, the dynamic Geozone is deleted automaticaly.

I think this is the last "." on the i for anti theft pursposes :-)

Any comments?

Thanks

Wolf.
