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.
