When you click Motion detection
menu, the Motion detection menu appears.
Using this menu, you can set the conditions for
activating the built-in "Motion detection" function.
Motion detection detects moving objects in the camera

when a motion detected under the motion detection
setting passes, appears in or disappears from a specified
area or inspection line.
The motion detection function and the VMF function
can independently set off an alarm at the time of
detection.
Note
The simple motion detection function is available for
SNT-EP104 and SNT-EP154.
See "The simple motion detection function" on page 79.
What are VMF functions-Video
Motion Filter
VMF functions are for inspecting whether a moving
object detected under the motion detection settings
passed, appeared in or disappeared from a specified area
or inspection line.
The inspection method is selected from Pass/Presence/
Appear/Disappear/Volume, and also allows for a
maximum combination of three, which can be
simultaneously or sequentially executed. In the VMF
setting, up to three patterns can be kept for each preset
for the current camera position.
Pass
A reference passage line is determined, and when a
moving object passes the setting line, an alarm is set off.
FTP client alarm sending, image memory alarm
recording and/or audio file playback can be performed
in synchronization with this alarm.
Presence
When the reference object acknowledged by the system
is present after a certain period of time has elapsed, an
alarm will be set off. FTP client alarm sending, image
memory alarm recording and/or audio file playback can
be performed in synchronization with this alarm.
