The alarm search feature searches for alarm events, and displays the search results in the [Alarm
Search] window as either an alarm list or thumbnail view, allowing you to select an alarm event
and play back the associated video file(s).
To use this search mode, click the [ALARM] button on the control panel to navigate to the [Alarm
Search] window.
To switch between the alarm list and thumbnail view, use the [LIST] and [THUMBNAIL] buttons
provided on this window.
The number of alarm event log entries that can be retained on a single hard disk is limited as
follows:
Once the upper limit has been reached, alarm event log entries are added to and deleted from the
hard disk on a first-in first-out basis, and deleted entries no longer appear on the alarm list or
thumbnail view.

You can also access the [Alarm Search] window by selecting the [Alarm Search] option on
the context menu of the tree list. In this case, even if the [LIST] button is not clicked, the DVR
alarm event log is automatically loaded and displayed on the alarm list.
