Configure each device differently - or distribute one device's settings to the whole Tigermeeting suite infrastructure by chosing the "set for booking devices".
...means every single configuration parameter including, Time zone, language, Video player... can be distributed for all devices - but in the same time it is easily possible to keep the devices unique - for example disable on screen booking for those screens that are in public spaces.
The Tigermeeting Admin app is used to manage all the devices.
