B. Frequently asked questions
Q. What if I forget my password?
A. Every access to Video Server 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 Video Server 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 Video Server after it is authenticated?
A. There are many possible scenarios regarding this problem,
1.If you have just installed Video Server and are unable to watch the video, check the video
modulation on the Configuration page.
2.If Video Server is well installed and you are accessing Video Server 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 Video Server 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 Video Server. It is maintained by a real-time
clock inside and automatically synchronizes with the time server if Video Server is connected to
the Internet and the function is enabled. Differences of several hours may result from the time
zone setting.
Q. Why does the image not refresh regularly?
A. In a modem environment, it is because the bandwidth of PPP connection is far less than
Ethernet. If the difference of the timestamp is not stable, adjust the UART FIFO lower in both
receiving and transmitting from modem property in the control panel. While in Ethernet, it may
be due to time taken in storing snapshots into memory upon events occurring.
Q. How does Video Server detect the supported PTZ cameras automatically?
A. If there is no camera detected, Video Server will monitor the CTS of the camera control cable
