Notes on Sensor Recording, Motion Detection Recording, Intelligent Function Recording and Volume Detection Recording (RM-64/25/9)
When an event occurs, data is saved in the Storage Server as an operation record. As the number of operation records increases, operation during event detection and the search and Viewer response speeds may be affected.
Notes on Using Motion Detection Recording / Intelligent Function Recording
The motion detection feature notifies you there is motion in an area when motion is not ordinarily expected. Do not use this feature for busy areas where motion detection may be triggered frequently.
Configure motion detection on the camera side. If you configure motion detection on the Storage Server side, the load on the Storage Server may increase, resulting in decreased recording performance.
Use intelligent function recording instead of motion detection recording.
You cannot set motion detection on the camera.
Notes on Storage Server Operation
We recommend that you dedicate the Storage Server computer exclusively to running this software.
Be sure to avoid the following on the Storage Server 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.
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.
The additional processing load from running applications other than this software may affect recording performance.
This software uses the TCP port numbers 80, 443, 11080 and 2380. These ports should not be used by other applications.
Calculating Network Bandwidth
You need to consider the network bandwidth if you want to use a network camera for recording and live view.
You must calculate the network bandwidth for the Storage Server and the Viewer.
When using the VB-H41 for example, calculate the bandwidth as follows if you use one Storage Server (320 x 240 1 fps) and two Viewers (320 x 240 5 fps):
10.8 (KB/frame) x 1 (frames/sec.) x 8 (bits) = 86.4 Kbps
10.8 (KB/frame) x 5 (frames/sec.) x 8 (bits) = 432 Kbps
Therefore, the required network bandwidth is calculated as follows: 86.4 Kbps x 1 + 432 Kbps x 2 = 950.4 Kbps (approx. 0.9 Mbps)
