Before Starting Operations <Important>
It is recommended that you perform tests under actual conditions before starting
operations.
This recording software may not operate as your settings in recording or
displaying live video, depending on the capabilities of your PC and the
network environment.
When 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.
The performance of storage servers and viewers may be negatively affected
on the PC, where anti-virus software or firewall is running.
When using a proxy server (→P. 57, P. 79)
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.
If you are operating using IPSec, the recording and display performance
may be degraded.
Refer to “Notes on Operating Environment” (→P. 24~27) for information on
OS you use.
When recording to a NAS server, it is recommended to separate the
communication networks for the camera and NAS.
Use recommended NAS servers with Windows Storage Server 2003 or
Windows Storage Server 2003 R2.
Although the audio function of the VB-C60, VB-C300, VB-C50i, VB-C50iR,
and VB-C50FSi can also be used, take note of the following warnings.
• The VK Viewer supports audio transmission and reception.
• Audio data can be recorded. However, audio data cannot be recorded
individually, and must be recorded together with video data.
• Only when playing video, the recorded video (JPEG
) is synchronized with
the recorded audio. However, the audio and images may not synchronize
depending on the environment (→P.114).
• The audio stream may be interrupted due to the performance of your PC
and the network environment.
• The audio function is not available via a proxy server.
• Audio may be interrupted on the PC where anti-virus software is running.
The software may not be able to record video, if you use it under the
condition where the IP address of storage servers or camera servers are
occasionally changed. So, please be sure to use fixed IP addresses.
