Important: Before Starting Operations
It is recommended that you perform tests under actual conditions before starting operations.
z 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.
z 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.
z The performance of storage servers and viewers may be negatively affected on the PC, where anti-virus
software or firewall is running.
z 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. (
 P. 3-9, P. 4-5)
z If you are operating using IPSec, the recording and display performance may be degraded.
z See "Notes on Operating Environment" ( P. 1-12 ~ P. 1-16) for information on OS you use.
z When recording to a NAS server, it is recommended to separate the communication networks for the camera
and NAS.
z Use recommended NAS servers with Windows Storage Server 2003 or Windows Storage Server 2003 R2.
z Although the audio function of the VB-C500VD, VB-C500D, 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. 4-35).
• 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.
z 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.
