Automatic video/image recorder

I want to use the camera embedded in Android tablets as a basic and light videosurveillance system for the home automation market In order to have a light UI, I want very few interaction with the app, as it simply records in background what happens in a let's say 48h cycle. If something happen (for example a robbery), the user must stop the recording within this 48h. Features: - Continuous video recording, with user-defined length and video quality, with sound option - Cyclic recording on SD card; i.e. the card never fills up - Background video/photo capture, with optional buttons over other applications - Visual motion triggered function: the camera will start auto-capturing any motion within its field of vision, and then save them - Autorun of the app when tablet is powered on - Videos/photos are timestamped & geotagged - App2SD - Languages: English
