B. Frequently Asked Questions (FAQ)
Q What if I forget my password?
A After the Administrator's password has been assigned, all 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 it 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.
4.
If only "A" is shown below the image (meaning for audio), check either of the media options that contain
"Video" in the client settings page.
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 the 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 the ceiling?
A Yes. There are flip and mirror options in the video configuration page to correct the images for upside down installation.
Q The image is not clear enough.
A Adjust the "Focus" and "Zoom" to improve the image. You can also try to tune other video/image settings to achieve
the best visual effect. Also notice that the power line frequency must match the local utility to synchronize and minimize
the effect of flickering fluorescent lights.
Q Why does the image not refresh regularly?
A Some anti-virus programs filter the received web content. It takes time to perform data examination and affect
streaming applications such as that of the network camera. However, it only affects the HTP mode of the network camera.
If the network allows only HTTP mode, disable the web filtering function of the anti-virus program temporarily. During
this period, the User should be aware of the risk of malicious network activity.
