Operating Environment

Before starting operations with VK-64
It is recommended that you perform tests under actual
conditions before starting operations.
Recording and display of live videos may not be provided as
configured because many factors (such as network environment and
PC performance) affect the actual performance of VK-64.
When the load on your computer CPU and hard disk is high, the
specified frame rate may not be available, or the video recording may
be interrupted or the Viewer operation may take longer. Also, when
available disk space is low, the disk load may increase and the video
recording may be interrupted due to deletion of the recorded video file
(tP.24).
Using anti-virus and firewall software may affect Storage Server and
Viewer operations.
When using a proxy server
If you use a proxy server, recording frame rate may not be
achieved as specified or live video monitoring may be
interrupted. Also, communication between the Storage Server
and Viewer may occasionally be disconnected.
When using the Audio feature (VB-C50i, VB-C50iR and VB-C50FSi)
The Admin Viewer supports audio transmission and reception.
Audio recording is not available.
The audio and video may be out of sync.
Depending on the performance of your PC and network
environment, the audio stream may be interrupted.
The audio feature is not available via a proxy server.
If you use a PC on which anti-virus software is installed, the
audio stream may be delayed or the audio stream may be
temporarily interrupted.
Note
Using the Storage Server with Windows XP SP2
If your Storage Server is not installed on the same PC as your Viewer, you will need to change
your Windows firewall settings for the Storage Server on the PC with Windows XPSP2.
After installation of the Storage Server on a PC with Windows XPwith SP2:
1. From the Windows Start menu, launch the Control Panel.
2. In Control Panel, select Windows Firewall. If Windows Firewall is not shown, select
Security Center and then select Windows Firewall.
3. In the Windows Firewall dialog, select the Exception tab and then click Add Port....
4. In the Add a Port dialog, enter a name for the Storage Server, e.g., ‘VK-64 Storage
Server’.
Enter the Port number as ‘80’. Make sure the TCP protocol is selected and click OK.
5. In the Windows Firewall dialog, your Storage Server is now listed. Make sure it is
enabled (checked). Click OK to close the dialog.
Settings are now complete.
If more than ten camera servers out of all registered ones cannot be connected to Storage Servers,
the CPU load will be heavy and Storage Server and recording operations may take longer.
