This Surveillance Camera example app demonstrates the usage of Nokia's Notifications API. The Notifications API lets you add real-time push notifications to your client applications. This example consists of two mobile apps. The Windows Phone Silverlight application uses Service API to send push notifications to a Qt Quick app in a Symbian device. In this example the Silverlight application is the actual surveillance camera and seeks movements in the camera viewfinder. The Qt application receives alert notifications from the Silverlight application when movement happens. Both applications authenticate into Notifications Service for sending and receiving alert notifications.
