Points to notice concerning motion detection
• If changes are detected repeatedly, alarm recording is also started repeatedly. Thus functions such as setting
change, etc., will not be accepted. In this case, press the ALARM INTERRUPT button to forcibly stop the motion
detection function for a period of 5 minutes. During this time, settings can be changed. This manual stop is automati-
cally restored after 5 minutes and the history of the manual stop is left in the screen. To
cancel the alarm interrupt, press the ALARM INTERRUPT button again. The ALARM INTERRUPT button does not
function while the menu screen is displayed on the monitor.
• For the input signals of alarm recording, ALARM IN terminal on the rear panel is constantly given priority over the
others. If the motion detection setting is active, alarm recording is started when the ALARM IN terminal is grounded
or when motion is detected.
• The motion detection of this unit may not operate correctly depending on the conditions of the input video signals
especially when the “SENSITIVITY” is set to high setting. Be careful when connecting to a system, etc., that is set to
alarm when the motion detection function of this unit is operated.
• To perform alarm recording during motion detection, set “TRIGGER” in the screen to “MD,”
“MD/EXT,” or “MD&EXT” and set “A-PPS” of the corresponding camera number in the to
other than “- - - - - -.”
• Motion detection does not operate while making settings in the screen.
• The motion may not be detected when many motions are detected or many alarm signals are input simultaneously.
■ MD LOCK OUT TIME
This item is used to restrict motion detection function in
order to control the recording to prevent the continuous
recording of the same image. Once the unit detects motion
and starts alarm recording, the unit ignores the input of
mortion detection for the time period set in the MD LOCK
OUT TIME. Thus alarm recording is not extend for that time
and the unit prevents an excess of continuous recording of
the same object.
Set the setting value carefully because the
necessary image may not be recorded due to the
restriction of the alarm recording. It is recommended
to set “MD LOCK OUT TIME” to “OFF” when there
is no need to set this item.
This function restricts the detection of the
coutinuous motion for the specified time period. The
number of alarms listed in alarm list may increase
depending on the setting.

1. In “SELECTION CAMERA NUMBER,” select the camera
for which the MD lock out time is set.
2. Display the desired setting in “MD LOCK OUT TIME” and
press the ENTER button.
• The setting item is determined.
The motion detection function may not start
immediately after cancelling alarm interrupt.
