Searching for event logs
The DVR compiles a log of events, such as the start or end of video recording,
DVR notifications, and alarms, through which you can easily search. Logs are
categorized by the following types:
• Alarm: Includes motion detection, tamper detection, and other alarm events
• Notifications: Includes system notifications such as video loss, HDD failures,
and other system-related events
• Operations: Includes users access to the web interfaces and other
operational events
• Information: Includes general information on the DVR actions, such as the
start and end of video recording, etc.
To search for logs, click the Log tab in the browser toolbar, select a log type,
specify a date and time range, and then click Search .
Dual streaming
The DVR allows you to view from up to 16 cameras over a network. Dual
streaming allows high quality video to be viewed in one stream (Main stream)
and lower quality video to be viewed in another stream (substream) that can be
easily streamed through a narrow bandwidth.
The normal stream has the frame rate, quality, and resolution as configured in
the encoding menu. However, in a thin stream data thinning has been carried out
so that it has a lower frame rate, quality, and resolution. This allows more video
to be recorded on the HDD.
Dual streaming is available in both live and recording modes.
