B. Frequently asked questions 
Q What if I forget my password? 
A After the Administrator's password has been assigned, every access to the Network 
Camera needs authentication. If you are one of the managed users, you have to ask 
the Administrator for the password. If you are the Administrator, there is no way to 
recover the root password except by restoring the factory default settings. Refer to 
Appendix A for the procedures. 
 
Q Why can I not watch video from the Network Camera after it is authenticated? 
A There are many possible scenarios regarding this problem, 
1. If you have just installed the Network Camera and are unable to watch the video, 
check if the heartbeat LED is blinking or the lens cap is off. If the heartbeat LED is dim, 
perform the software installation again. 
2. If the Network Camera is well installed and you are accessing the 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, and the message over the image window 
is showing "connecting", the network traffic may be too crowded. 
 
Q What is the plug-in for? 
A The plug-in provided by the Network Camera is used to display motion pictures and 
audio in 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. Software installation may be regulated in some 
offices. 
 
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 the Network Camera. It is maintained 
by a real-time clock inside and can be automatically synchronized with the time-server 
if the Network Camera is connected to the Internet and the function is enabled. 
Differences of several hours may result from the time zone setting. 
 
Q Can I install it on ceiling? 
A Yes. There are flip and mirror options in the video configuration page to correct the 
images for upside down installation.
