Search event logs
The recorder compiles a log of events, such as the start or end of video recording, recorder
notifications, and alarms, through which you can easily search. Logs are categorized by the
following event types:
• Alarm: Includes motion detection, tamper detection, video tampering, and other alarm
events
• Notification: Includes system notifications such as video loss, HDD failures, and other
system-related events
• Operation: Includes users access to the web interfaces and other operational events
• Information: Includes general information on the recorder actions, such as the start and
end of video recording, etc.
Up to 2000 log files can be viewed at once.
Log files can also be exported onto a USB device. The exported file is named according to the
time it was exported. For example: 20140729124841logBack.txt.
Note: Connect the backup device, such as a USB flash drive, to the recorder before
commencing the log search.
