B. Frequently asked questions
Q. What if I forget my password?
A. Every access to Network Camera 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 Network
Camera 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 Network Camera after it is authenticated?
A. There are many possible scenarios regarding this problem,
1.If you have just installed Network Camera and are unable to watch the video, check the
video modulation on the Configuration page.
2.If Network Camera is well installed and you are accessing Network Camera for the first
time using Internet Explorer, adjust the security level of Internet Explorer to allow
installation of plug-ins.
3.If the problem still exists after adjusting, the current users may be over the system
allows.
Q. What is the plug-in for?
A. The plug-in provided by Network Camera is used to display motion pictures on Internet
Explorer. If your system does not allow installation of any plug-in software, the security
level of the web browser may need to be lowered. It is recommended that you consult your
network supervisors in your office regarding adjustment of the security level.
Q. Why is the timestamp different from the system time of my PC or notebook?
A. The timestamp is based on the system time of Network Camera. It is maintained by a
real-time clock inside and automatically synchronizes with the time server if Network
Camera is connected to the Internet and the function is enabled. Differences of several
hours may result from the time zone setting.
