The app is a copy of ISeeYou basic but improved with the "motion follower" feature: the automatic narrowing of the processing area basing on motion localization.
If a moving entity occupies only a sub-part of the capturing area then the app makes a "zoom-in" and follows the moving entity.
When another moving entity enters the scenario covered by the capturing area the app makes a zoom-out to embrace all the moving entities. This allows the saving of the storage occupation of recordings that capture this way up to only a sixteenth of the capturing area, and provides each recording content focused on the moving entities which the user is interested in.
