Do I always need Internet connection to use OnSign TV?

The OnSign TV Player has a backup mode that keeps your campaigns rolling when the Internet connection is lost.Besides, you can even update your campaigns on offline players with an USB stick (check tutorial).

However, there are some reservations. The following features will only work when your device is connected to the Internet: Remote View, Real-time Event Reporting, Campaigns on Demand, Current Campaign Thumbnail and the ability to remotely reboot, shut down and change your device or update your player version.
