Recording Live Video■About Live Video Recording
The VA-SW3050 enables you to record live video from cameras in the following four ways.
MEMO:
• The recorded video data is stored on the PC’s hard disk drive. The preferences on storing the
recorded video can be configured in the [DATA Storage] screen (see page 41).
• Set video quality, etc. in normal recording on the [Camera Setting] screen (see page 10).
Note:
• If simultaneously accessing from multiple PCs, alarm recording can only be performed from one.
• Depending on the network environment, PC performance or number of PCs connected, it may not be
possible to record at the designated recording rate.

Recording on

Records both the pre- and post-alarm video before
and after the alarm signal respectively on the
camera’s memory by specifying the recorded video
size. The recorded alarm video is transferred one by
one to the PC and stored on the hard disk drive.
Use the
[Alarm Setting]
screen to configure the total
alarm video size and the ratio between the pre- and
post-alarm video size in alarm recording.
When you perform the pre-alarm recording, you can
check the video from the point immediately before the
alarm signal while playing the alarm video.
