Alarm recording
Select the Alarm tab inside the Recording Setting menu (a screen similar to that in
Figure 15 would then pop up).
Check the “ON” box for corresponding camera to enable the alarm input and the
alarm recording function.
Input the alarm recording duration in the (in sec) column.
Check the Nopen (Normally open) box if the switch connected to the alarm input is a
normally opened switch.
Input the frame per second for individual cameras. The default frame rate is 25 f/s.
Pre-alarm recording
Check the “ON” box in the pre-alarm column to enable the pre-alarm function of the
corresponding camera(s).
Input the pre-alarm duration from one to 60 seconds.
Every time when the alarm is triggered, the pre-alarm recording image will be saved
into a permanent file, which can be retrieved for playback.
Click OK to confirm the input.
Tip:
Pre-alarm lets you review images prior to the actual happening of
the alarm event. Also, pre-alarm keeps the images only when the
alarm is actually taking place, so that storage space can be used
more effectively. This mode is more effective than that in
scheduled recording.
