A. Frequently Asked Questions
Q:
What if I forget my password?
A:
Every access to the IP camera needs authentication, unless the admin password is set up as blank. If you
are one of the managed users, you will need to ask the administrator for the password. If you are the
administrator, there is no way to recover the admin password. The only way to regain access to IP camera
is to utilize the
RESET button to restore the factory settings (see Chapter 1 for details).
Q:
Why can’t I see video from the IP camera after it has been authenticated?
A:
There are many possible
scenarios:
(a)
If the IP camera is installed correctly and you are accessing the IP camera for the first time using
Internet Explorer, adjust the security level of Internet Explorer to allow installation of plug
-ins.
(b)
If the problem still exists, the n
umber of users accessing the IP camera at the same time may exceed
the maximum that the system allows.
(c) If the video is still not
displayed
, please try to run the Factory default to see if it is in work properly.
Q:
What is the plug
-in for?
A:
The
plug-in provided by the IP camera is used to display motion pictures. The plug-
in is needed because
Internet Explorer does not support streaming technology. If your system does not allow installation of
plug
-in software, the security level of the web brow
ser may need to be lowered. It is recommended that
you consult the network supervisor in your office before adjusting 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 sys
tem time of the IP camera. It is maintained by an internal real-time
clock, and automatically synchronizes with the time server if the video encoder is connected to the
Internet and the function is enabled. Differences of several hours may result from the time zone setting.
Q:
How many users are allowed to access the IP camera at the same time?
A:
Basically, there is no limitation. However the video quality also depends on the network
. To achieve
the best
effect, the VPort 26 IP camera will allow 10 video streams for udp/tcp/http connections. We
recommend using an
additional web server that retrieves i
mages from the IP camera periodically if you
need to host a large number of users.
Q:
What is the IP camera’s video rate?
A:
The codec can process 30 frames per second internally. However the total performance is subject to many
variables, as listed below:
1.
Network throughput.
2.
Bandwidth share.
3.
Number of users.
4.
More complicated objects result in larger image files.
5.
The speed of the PC or notebook that is responsible for displaying images.
