Q I cannot hear any sound while watching.
A If
“V
_ONLY
”
appears above the image, click on connection type to uncheck
“Disable
audio.
”
If
“V”
appears instead of
“AV
,
”
the sound card in your PC may not be properly installed. If
“AV”
displays, check the audio source of the DDK-3000 Video Encoder.
Q How many users are allowed to watch the DDK-3000 Video Encoder at the same time?
A Too many users requesting real-time multimedia content will jam the network. For best results, the
DDK-3000 Video Encoder is designed to accommodate a maximum of ten (10) users to watch and listen
to the DDK-3000 Video Encoder at the same time. For a larger number of users, it is recommended to use
an intermediary web server to host the retrieving content from the DDK-3000 Video Encoder.
Q How fast is the video rate of the DDK-3000 Video Encoder?
A The MPEG-4 codec engine can process 30 frames per second internally. However the total
performance is subject to many coefficients as follows:
• Network throughput
• Bandwidth share
• Number of users
• The complexity and detail of objects and activity in the field of view
• The processing capability of the PC or notebook computer that is responsible for displaying images.
Q How can I keep the DDK-3000 Video Encoder as private as possible?
A The DDK-3000 Video Encoder is designed for surveillance purposes and has many flexible interfaces.
The user authentication and special confirmation in installation can keep the DDK-3000 Video Encoder
from unauthorized access. You may also change the HTTP port to a non-public number. The demo
account is good to separate guests from normal users and thus you can easily block guests at any time.
You can check the system log to examine any abnormal activities and trace the origins.
Q Why can I not access the DDK-3000 Video Encoder when I set up some options in the
application?
A Since the DDK-3000 Video Encoder is a
“network
device,
”
any incorrect network settings will make
it inaccessible. If this happens, restore the factory default settings by following the procedures in
Appendix A.
