Introduction System Design 1 „ Storage Server Operation Considerations We recommended that you dedicate the Storage Server computer exclusively to running this software. Be sure to avoid the following on the Storage Server computer: • Running Web server software on the computer You cannot operate the Storage Server on a computer where Web server software such as Windows standard IIS (Internet Information Server) or Apache is already installed. The Storage Server uses HTTP protocol to communicate with cameras. Therefore, the Storage Server may not work normally if other Web service applications exist on the same computer. The HTTP port used by this software is 80 and cannot be changed. • Running database server software (e.g., SQL Server, Oracle) on the computer Database processing can place a load on the hard disk that may affect recording performance. Conversely, this software may affect database server performance when it performs tasks that place a load on the hard disk. • Using the computer as a file server The hard disk is frequently accessed when the computer is used as a file server, and this may affect recording performance. In addition, the Storage Server is more likely to run out of disk capacity if the computer is operated as a file server. • Running other applications on the computer The additional processing load from running applications other than this software may affect recording performance. This software uses the TCP port number 80, 443,10080 and 2380. These ports should not be used by other applications. Network Bandwidth Considerations You need to consider the network bandwidth if you want to use a network camera for both recording and live view. You must calculate the network bandwidth both for the Storage Server and the Viewer. For example, if you use one Storage Server (QVGA 1 fps) and one Viewer (QVGA 5 fps), calculate the bandwidth as follows: • Bandwidth for recording 15 (KB/frame) x 1 (frames/sec) x 8 (bits) = 120 Kbps • Bandwidth for live view (per Viewer) 15 (KB/frame) x 5 (frames/sec) x 8 (bits) = 600 Kbps Therefore, the required network bandwidth is calculated as follows: 120 Kbps x 1 + 600 Kbps x 1 = 720 Kbps 1-9

Storage Server Operation Considerations
We recommended that you dedicate the Storage Server computer exclusively to running this software.
Be sure to avoid the following on the Storage Server computer:
•
Running Web server software on the computer
You cannot operate the Storage Server on a computer where Web server software such as Windows standard IIS
(Internet Information Server) or Apache is already installed.
The Storage Server uses HTTP protocol to communicate with cameras. Therefore, the Storage Server may not work
normally if other Web service applications exist on the same computer.
The HTTP port used by this software is 80 and cannot be changed.
•
Running database server software (e.g.,
S
QL
S
erver, Oracle) on the computer
Database processing can place a load on the hard disk that may affect recording performance. Conversely, this
software may affect database server performance when it performs tasks that place a load on the hard disk.
•
Using the computer as a file server
The hard disk is frequently accessed when the computer is used as a file server, and this may affect recording
performance. In addition, the Storage Server is more likely to run out of disk capacity if the computer is operated as a file
server.
•
Running other applications on the computer
The additional processing load from running applications other than this software may affect recording performance.
This software uses the TCP port number 80, 443,10080 and 2380. These ports should not be used by other applications.
Network Bandwidth Considerations
You need to consider the network bandwidth if you want to use a network camera for both recording and live view.
You must calculate the network bandwidth both for the Storage Server and the Viewer.
For example, if you use one Storage Server (QVGA 1 fps) and one Viewer (QVGA 5 fps), calculate the bandwidth as follows:
•
Bandwidth for recording
15 (KB/frame) x 1 (frames/sec) x 8 (bits) = 120 Kbps
•
Bandwidth for live view (per Viewer)
15 (KB/frame) x 5 (frames/sec) x 8 (bits) = 600 Kbps
Therefore, the required network bandwidth is calculated as follows:
120 Kbps x 1 + 600 Kbps x 1 = 720 Kbps
