To exit Brancam you can click on the 'Exit' button in the upper right corner or you can directly close the browser. 

You should always leave Brancam via the ' Exit' button. Otherwise, there is a risk of someone else using the application without your consent. 

For this reason, Brancam rejects the user automatically when it detects that the system has been for a while with no movement. Brancam interprets you've finished using it and you forgot to log-out, so that it closes only for security reasons. However, if you check the "Remember Me" option at the time of logging on, the system will not reject you out.
