B. Frequently asked questions
Q. What if I forget my password?
A. Every access to VisualServer needs authentication. If you are one of the managed users, you have to
ask the administrators for the password. If you are the administrators, there is no way to recover the root
password. The only way to regain access to VisualServer is to utilize the default setting button on the rear
panel to restore the factory settings and reinstall it.
Q. Why can I not watch video from VisualServer after it is authenticated?
A. There are many possible scenarios regarding this problem,

adjustment of the security level.
