Building Networks for People
continuously. As long as the CTS is detected, Video Server will try to handshake with supported cameras until a supported camera is found. There is no more camera detection once a PTZ camera is recognized.
Q. How many users are allowed to watch Video Server at the same time?
A. Basically there is no limitation of users. However the video quality also depends on the network bandwidth. To achieve the best effect, Video Server will allow several users to be connected. It is recommended to build another web server to host a large quantity of users by retrieving images from Video Server periodically.
Q. How fast is the video rate of Video Server?
A. The MPEG4 codec can process 30 frames per second internally. However the total performance is subject to many coefficients as follows:
1.network throughput.
2.bandwidth share.
3. number of users. | 格式化: 項目符號及編號 |

4.the complicated objects in view results in larger image file.
5.the level of your PC or notebook which is responsible for displaying images.
In general, the transfer rate in a general local network environment can achieve over 200 kilobytes per second and approximately 10 to 20 pictures of a normal environment per second.
Q. How can I keep Video Server as private as possible?
A. Video Server is designed for surveillance purposes and has many flexible interfaces. The user authentication and special confirmation in installation can keep Video Server from unauthorized access. You may also change the HTTP port to
Q. I have a PTZ camera that is not on the supported list. How can I control it?
A. Video Server provides a custom camera command interface to control the cameras that are not supported. The details are described in the manual. Be sure the COM port settings are applied to the camera specification. The camera control cable included is shown in the package content. Prepare your own cable if necessary. The general PTZ command is composed of one start command and one stop command. When editing both commands in the edit box of the configuration page, use comma(s) to separate commands. Each comma represents 200 milliseconds. If the user has some serial control device other than the PTZ camera, the special URL is provided to send the desired commands. For quick access, integrate the URL to another homepage on your own web server.
