With alerts you can easily override playlists with high importance messages. Carousel provides 2 levels of alerts. Zone alerts that just override the content in a particular zone and Full Screen alerts that override an entire channel. The great thing about the way alerts work in Carousel is that you can create user accounts that can only create alert content. This allows you to give emergency personnel access to create emergency messages without giving them access to the entire signage network. Even more, the user interface for these users will only show them what they need to get the job done!
