Troubleshooting
Q:Why can’t I watch video from Video Server after it is authenticated?
A:There are many possible scenarios regarding this problem,
1.If you have just installed Video Server and are unable to watch the video, check if the video input is enabled and check the video modulation on the Configuration page.
2.If Video Server is installed correctly and you are accessing Video Server for the first time using Internet Explorer, adjust the security level of Internet Explorer to allow installation of the
3.If the problem still exists after making the adjustment, the current number of users may be greater than what the system allows.
4.If you are using a demo account, the administrator may hide the video from public view.
Q:How can I use a name instead of the IP address to connect Video Server?
A:To allow users to connect to Video Server through an easily memorized name, administrators must first configure the network’s domain name server. Here is an example: the administrator installs the Video Server with a reserved IP address and assigns it a name on the domain name service, then users can connect to Video Server by typing a name instead of an IP address. If there is DHCP service on the network, the IP address must be excluded on the DHCP service to prevent an IP conflict.
Q:What is the
A:The
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 an internal
Q: Why does the image not refresh regularly?
A:In a modem environment, it is because the bandwidth of PPP connections is much lower than for Ethernet. If the difference of the timestamp is not stable, use the modem property on the control panel to adjust the UART FIFO to a lower level for both receiving and transmitting. In an Ethernet environment, it may be due to the time taken for storing snapshots into memory when events occur.
Q: How many users are allowed to watch Video Server at the same time?
A:To achieve the best effect, Video Server will allow a maximum of twenty users to connect at the same time. Excess users can get an
Q:How fast is the video rate of Video Server?
A:The JPEG codec can process 30 frames per second internally. However, the overall performance is subject to many different factors, such as:
1.network throughput,
2.bandwidth share,
3.number of users,
4.number of video inputs accessed at one time,
5.viewing complicated objects results in a larger image file,
6.the level of your PC or notebook that is responsible for displaying images.
In general, the transfer rate on a general local network environment can achieve over 200 Kbytes per second and approximately 10 to 20 pictures of normal environment per second. The general frame size is illustrated in the following table for your reference.
