D Configuration Name
Enter a name for the area configuration.
The name you enter here is used when configuring an
alarm recording schedule to be triggered by movement in
the motion detection area.
E VMD Mode
Select the Advanced mode or Standard mode.
Always verify your operating environment first, because
performance may vary depending on the mode.
• The Standard mode can perform motion detection
simultaneously with more cameras than the Advanced
mode.
• The Advanced mode offers better detection accuracy.
• Note that when the VMD mode is changed, the default
values for [Previous Frame] and [Candidate Frame] are
configured for each mode.
• When the codec is MPEG4, only the Advanced mode is
supported.
Caution
When the codec for cameras set to the Standard mode is
changed to MPEG, the VMD mode is switched
automatically to the Advanced mode. In addition,
[Previous Frame] and [Candidate Frame] are set to the
default values for the Advanced mode.
