Trigger1
SD card recording is performed when conditions set for the alarm setting items
are met. The alarm event recording interval for when an alarm is triggered is from
60 seconds before the trigger (pre-trigger) to 60 seconds after the trigger
(post-trigger), for a total of 120 seconds.
Alarm recording-related setting items are displayed when "Alarm" is selected.
Memo：
Even if another trigger is detected within 60 seconds of the first trigger, it will
not register in the event list.
If another trigger is detected during alarm recording, recording is extended 60
seconds from the original end point.
If less than 60 seconds have passed since video recording was initially started,
the pre-trigger time will be less than 60 seconds.
When the link between the camera and the network is down, the camera image is
recorded to the SD card.
Memo：
When the LAN cable is removed from the camera, the link with the network is
down, but when the camera is supplied with electricity by the PoE, as the
power is cut at the same time, the camera image will not be recorded to the SD
card.
Select the 1st trigger to start alarm recording.
