3.1 Introduction of Live View
Live view shows you the video image getting from each camera in real time. The NVR
automatically enters Live View mode when powered on. It is also at the very top of the menu
hierarchy, thus pressing the ESC many times (depending on which menu you’re on) brings you to
the Live View mode.
Live View Icons
In the live view mode, there are icons at the right top of the screen for each channel, showing the
status of the record and alarm in the channel, so that you can know whether the channel is
recorded, or whether there are alarms occur as soon as possible.

3.2 Operations in Live View Mode
In live view mode, there are many functions provided. The functions are listed below.
•Single Screen: showing only one screen on the monitor.
•Multi-screen: showing multiple screens on the monitor simultaneously.
•Auto-switch: the screen is auto switched to the next one. And you must set the dwell time for
each screen on the configuration menu before enabling the auto-switch.
Menu>Configuration>Live View>Dwell Time.
•Start Recording: normal record and motion detection record are supported.
•Output Mode: select the output mode to Standard, Bright, Gentle or Vivid.
•All-day Playback: playback the recorded videos for current day.
•Aux/Main output switch: the NVR checks the connection of the output interfaces to define
the main and auxiliary output interfaces. The priority level for the main and aux output is
HDMI>VGA>CVBS. This means if the HDMI is used, it will be the main output. If the
HDMI is not used, the VGA output will be the main output. See the table below.

And the HDMI, VGA and CVBScan be used at the same time.
When the aux output is enabled, the main output can’t do any operation, and you can do some
basic operation on the live view mode for the Aux output.

CVBS output. When you enable the audio in both the CVBS and VGA audio output, the
audio from the audio out interface is for VGA.
2. For LTN7604-P4, LTN7608-P4 and LTN7608-P8, VGA and HDMI output are only
