B. Frequently asked questions
Q. What if I forget my password?
A. Every access to NetworKam 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 NetworKam 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 NetworKam after it is authenticated?
A. There are many possible scenarios regarding this problem,
1.If you have just installed NetworKam and are unable to watch the video, check the video modulation on
the Configuration page.
2.If NetworKam is well installed and you are accessing NetworKam 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 NetworKam 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 NetworKam. It is maintained by a real-time clock inside
and automatically synchronizes with the time server if NetworKam 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
