Before Starting Operation <Important>
Please be sure to perform operational tests in the actual environment before starting
operation.
Be aware of the following points prior to operation.
● Video recording and live viewing may not be done as your settings, depending on
the network environment and the PC’s performance.
● Under a heavy load on the CPU or disk of the PC, the recording may not be done at the
specified frame rate, recording may be suspended temporarily, or you may receive slow
responses to the viewer operation. Also, when the amount of free disk space becomes
low, recording may be suspended temporarily, because the disk load increases due
to deleting process of recorded video files.
● Operation and performance of storage servers and viewers may be affected on PCs,
where anti-virus software or firewall software is running.
● When using a proxy server, video recording may not be done at the specified frame rate,
or live viewing may become interrupted. Also, communication between a storage server
and viewer may be interrupted. In those cases, audio cannot be recorded.
