B. Frequently asked questions
Q What if I forget my password?
A
After the Administrator’s password is assigned, access to the DDK-3000 Video Encoder needs
authentication. If you are one of the managed users, you should request the password from the
Administrator. If you are the Administrator, there is no way to recover the root password except by
restoring factory default. Refer to Appendix A for the procedures.
Q Why can I not watch video from the DDK-3000 Video Encoder after authentication?
A
There are many possible scenarios regarding this problem.
1. If you have just installed the DDK-3000 Video Encoder and are unable to watch the video, check if
the heartbeat LED is blinking or the camera is properly connected. If the heartbeat LED is dim,
perform the software installation again.
2. If the DDK-3000 Video Encoder is properly installed and you are accessing the DDK-3000 Video
Encoder for the first time using Internet Explorer, adjust the security level of Internet Explorer to
allow installation of ActiveX plug-ins.
3. If the problem still exists after adjustment, and the message over the image window reads
“connecting
,” the network traffic may be too congested.
Q What is the plug-in for?
A
The plug-in provided by the DDK-3000 Video Encoder 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 DDK-3000 Video Encoder. It is maintained by a real-
time clock inside the unit and can be automatically synchronized with a time server if the DDK-3000
Video Encoder 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 the attached video camera on the ceiling?
A
Yes. There are flip and mirror options on the video configuration page to correct the images for upside-
down installation.
Q The image is not clear enough.
A
Make sure the attached analog camera is properly installed and focused. The image settings and white
balance can be fine-tuned to achieve the best visual effect. Also ensure that the power line frequency
matches 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 affects streaming applications such as the video. However it only affects the HTTP mode of the DDK-
3000 Video Encoder. If the network allows only HTTP mode, disable the web filtering function of the
anti-virus program temporarily. During the period, users should be aware of the risk of malicious network
activity.
Q I have opened motion detection windows, but it does not work.
A
If the motion detection windows are set up and names are assigned, check to see if the function is
enabled in the first line. While it is enabled, adjust the sensitivity and percentage and monitor the level
indicator for best results.
