You have installed your equipment at a wedding reception to allow guests to record video messages.
The bride has given you instructions that the system should not be used past 9 pm, but you're not going to be there to manually stop the system. This is where you can make use of RightBooth's Stop event rules to get the system to automatically shut down at a specified time.
In the screen shot below, you can see that we have set the stop time to 21:00 on the 10th May 2017...
Now at 9pm, RightBooth will stop the event playing and will then shut down the computer.
And don't worry, if someone is recording a video at 9pm, RightBooth will wait until they have finished before switching off.
