Motion detection tab — Set the 
motion/VMF detection
Motion detection detects moving objects in the camera 
image and outputs an alarm. In VMF, an alarm is 
notified when a motion detected under the motion 
detection setting passes, appears in, disappears from or 
shows any movement in a specified area or on an 
inspection line.
The motion detection function and the VMF function 
can independently set off an alarm at the time of 
detection.
What are VMF functions
VMF is a function for inspecting whether a motion 
detected under the motion detection setting passed, 
appeared in, disappeared from or shows any movement 
in a specified area or on an inspection line.
The inspection method is selected from Pass/Presence/
Appear/Disappear/Volume, and allows for a maximum 
combined inspection method of three, which can be 
simultaneously or sequentially executed.
Passing
A 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.
Existing
When a moving object in the designated area exists after 
a certain period of time has elapsed, it will set off an 
alarm. FTP client alarm sending, image memory alarm 
recording and/or audio file playback can be performed 
in synchronization with this alarm.
Appearance
When a moving object appears in the designated area, it 
will set off an alarm. FTP client alarm sending, image 
memory alarm recording and/or audio file playback can 
be performed in synchronization with this alarm.
