Simple motion detection function
The following three simple functions are provided for
motion detection. The simple motion detection function
is available on the SNT-EP104 and SNT-EP154.
Set the sensitivity of the motion detection. Set a scale
from  to .
Specify the size of moving object to be detected, from
three options: Large, Medium and Small.
If a moving object is shown in full screen, you can set
the degree of motion of the object to within a scale :
1 - 100 Check the current degree of motion on the level
meter and set the detection level referencing that value.
VMF configuration is not available when the simple
motion detection function is activated.

Audio detection detects sound picked up by a
microphone, and outputs an alarm beyond a certain
Select On to activate the function and set the sensitivity .
Set the Sensitivity to Low, High or Manual. If Manual
is selected, you may set the sensitivity manually.
Setting the Sensor input/Camera tampering detection/Motion detection/Audio detection — Event detection menu
Set the Manual sensitivity from 1 to 100, the larger the
number, the greater the sensitivity.
Detection status: When Audio detection is set to On in
the Audio detection tab, the detection status is
If excessive sound is picked up by the microphone,
"Detected" appears; otherwise "Non-detected" is
displayed. The input volume is indicated in a bar that
helps you to calibrate detection levels.
• Audio detection is not available on the SNT-EP104 or
• For the SNT-EX154, audio detection is only available
• Test audio detection to confirm that it is functioning as
• The audio detection function sets the detection level
automatically according to the statistical samples of
input volume and the sensitivity. Thus, the detection
level may differ even with the same sensitivity.
• The detection of input volume cannot be updated
when the Audio detection tab is open. This means at
this time the detection level is not adjusted
automatically according to the input sound. According
to the characteristics, test audio detection when the
Audio detection tab is open.
• Before setting sensitivity, in order to optimize
detection, place the microphone in an ordinary
location and sound environment for about
3 minutes before opening the Audio detection tab.
• The Audio detection alarm is off during playback of
• The Audio detection alarm is off while uploading
audio (from a computer).
