Q How can I use a name instead of the IP address to connect Network Camera?
A To allow users to connect to Network Camera through an easily memorized name, the
administrators must first configure the name server in his network. Here is an example:
the administrator installs the Network Camera with a reserved IP address and assigns it
with a name in the domain name service, then users can connect to Network Camera by
typing a name instead of IP address. If there is DHCP service in the network, the IP
address must be excluded in the DHCP service to prevent from IP conflict.
Q What is the plug-in for?
A The plug-in provided by Network Camera is used to display motion pictures on Internet
Explorer that does not support server push technology. If your system does not allow
installation of any plug-in software, the security level of web browser may need to be
lowered. It is recommended that you consult your network supervisor in your office
regarding the adjustment of 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 system time of Network Camera. It is maintained by a
real-time clock inside and automatically synchronizes with the time server if Network
Camera is connected to the Internet and the function is enabled. Differences of several
hours may result from the time zone setting.
Q Why does the image not refresh regularly?
A In a modem environment, it is because the bandwidth of PPP connection is far less
than Ethernet. If the difference of the timestamp is not stable, adjust the UART FIFO
lower in both receiving and transmitting from modem property in the control panel.
While in Ethernet, it may be due to time taken in storing snapshots into memory upon
events occurring.
Q How many users are allowed to watch Network Camera at the same time?
A To achieve the best effect, Network Camera will allow twenty users to connect at the
same time. Excess users can get an auto-refreshed still image in homepage instead. It is
recommended to build another web server to host a large quantity of users by retrieving
images from Network Camera periodically.
