I didn't use the camera based motion detection feature to turn the screen on/off. Screen on/off is a feature of their "PLUS" version. It is available to be called in the community device driver as well as through a REST interface (which the driver uses). I ended up using this driver with rule machine and my motion sensors to call screen on/off when motion was active/inactive in the area where the tablet is located. The REST interface screen on/off is mentioned here under "Device Info and Basic Features"
Anyway, not looking to use Fully Kiosk Browser as it's designed to be used with web based dashboards just throwing the idea of adding ability to your app to turn the screen on/off using similar methods (device driver capability and/or REST calls to the device) so it's not on all the time.
