1) Channel: specifies the recording channel after an alarm is generated. The
recordings of selected channels will be marked as alarm recordings.
2) Post Recording: specifies the duration, during which recording continues
after an alarm is cleared. Value range: 1-30 minutes. Default value: 1
Min.
3) Lock: specifies whether to lock alarm recordings. If this option is selected,
alarm recording will be locked once IO alarm is triggered. The recording
is unlocked after the alarm is cleared.
4) Linkage IO output: the IO output volume can be configured after the IO
alarm is triggered. The IO output can be configured and used only when
the UPS power box is used (conventional power boxes do not provide IO
outputs). The duration for IO output can be configured, and the value
range is 0 to 255 seconds.
5) Linkage Screen: specifies the screen to be displayed in live view after an
alarm is generated. By default, this parameter is set to None. You can also
set it to Single or Quad screen display.
6) Alarm Snap: specifies whether to capture images after an alarm is
generated. If an FTP address has been configured, channel capture will be
enabled after an IO alarm is generated, and captured images will be output
via FTP. If alarm evidence uploads parameters have been configured on
the platform, captured images can also be uploaded to the platform.
 Speed Alarm: allows you to enable the overspeed alarm function and set
Alarm Type to Alarm or Event. On the Overspeed Trigger screen, specify
Preload Speed Difference. A warning is generated if the difference between
the vehicle speed and limited speed is smaller than the value of this parameter.
An overspeed alarm is generated if the vehicle speed is greater than the limited
speed. The voices are different for the two alarms. Other parameters can be set
in the same way as for IO Alarm.
