A The plug-in provided by Video Server 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 Video Server. It is maintained by a real-time clock inside and automatically synchronizes with the time server if Video Server 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 watch Video Server at the same time?

It is recommended to build another web server to host a large quantity of users by retrieving images from Video Server periodically.
